PHP debugging

Saturday 02 of December, 2006
I needed to do some debugging of the LDAP authentication with Tikiwiki 1.9.7. I needed a way to see how variables were being set. I found this page on debugging (cache).

I created a file called lib/debug2.inc under /tiki and set the permissions for apache.

I added this line to tiki-index.php:
include ('lib/debug2.inc');

Once that's done, you use this line to print a variable:
debug2_(FILE, LINE, variablename, $variable);

The output is sent to /tiki/debug.out. I ran tail -f debug.out while I was working.

One thing to note., with this loaded, while everything else worked, I could not display tiki-index.php. I would get the error:
"File open failed - global.var.inc"

Fixing LDAP & Tikiwiki 1.9.x

Friday 01 of December, 2006
I use OpenLDAP to authenticate users for my Tikiwiki installation. Between version 1.9.4 and 1.9.6 LDAP auth broke. It looks like tiki upgrade the version of Pear::Auth they use. I found out the problem had to do with the LDAP connection not shoosing to switch to LDAP version 3 calls.

To fix this, there was a short term fix to add this at line 291 of the LDAP.php that comes with Pear::Auth (tikiwiki\lib\pear\Auth\Container\LDAP.php)
$this->options['version']=3;

This has the effect of adding version=3 to the options array that is passed to the LDAP connect method.

So that hack was ok for while, but the I got restless. I modified Tiki so that there is a version option on the Admin->login page. Set this to 3 and all is well.

Here's how:

In lib/userslib.php at line 632 add:
$options["version"] = $tikilib->get_preference("auth_ldap_version", 3);

In tiki-setup.php at line 1195 add:
$auth_ldap_version = "";
$smarty->assign('auth_ldap_version', $auth_ldap_version);

In tiki-admin-include-login.php at line 444 add:
if (isset($_REQUEST["auth_ldap_version"])) {
  $tikilib->set_preference("auth_ldap_version", $_REQUEST["auth_ldap_version"]);
  
  $smarty->assign('auth_ldap_version', $_REQUEST["auth_ldap_version"]);
    }

Lastly, in tiki-admin-include-login.tpl at line 201 copy the LDAP Admin Pwd line and change it to LDAp version and auth_ldap_version (I cannot copy that line here, the html screws up the page)



Podcast Converter

Wednesday 29 of November, 2006
I found a new Podcast called the Story of Digital Identity SToDID. No sooner did I discover it, then the host, Aldo Castañeda, switched to m4a format. He did so due to potential licensing and file size issues with mp3. See his comments in the comments for Episode #38 (cache) where we diascussed the issue.

Well, I own a Creative Zen Nomad Xtra and use it regularly to listen to podcasts. It does not support the m4a format. I went looking for a way to access the content, found a couple tools and wound up writing this Windows script to convert the file from m4a to mp3. It uses some open source tools — faad, lame and tag to do the heavy lifting. One caution - it removes the original .m4a file when complete. Instructions to stop that are included.

As an after thought, I added the ability to rip the audio m4v files as well.

I use Juice to download my podcasts and it provides a feature to run a command after each download. It provides two parameters for use with the command.
%f = filename
%n - podcast name

I use this command in juice:
start "postDL" cmd /c c:\acc\m4tomp3.cmd "%f" "%n"

The script access %f as %1 and %n as %2

@echo off
::m4ToMP3
::Greg Martin  11/29/06
::Converts m4a and m4v files to mp3 for use on a mp3 player
::  (note: if you've not seen them before, a double colon is similar to a comment (REM)

::sleep to give juice time to complete file write
sleep 5

set podname=%2
set origFileName=%1

:: since a specific filename is passed as %1 the 'for' does nothing except parse
:: the extension & filename
:: fext is set to file extension (.m4a  or mp3)
:: fname is set to filename (less extension)
for %%a in (%1) do set fext=%%~xa& set fname=%%~na& set fpath=%%~dpa

::Convert if needed
if %fext%==.m4a call :convertit %1
if %fext%==.m4v call :convertit %1
call :settag
goto :eof

:convertit
@echo export to wav
::use faad to decode to wav
faad %1
sleep 1
@echo convert to mp3
::use lame to encode to mp3
lame -h -b 96 "%fpath%%fname%.wav" "%fpath%%fname%.mp3"
:: cleanup (remove %origFileName% from the net line to keep the original file after conversion)
del %origFileName% "%fpath%%fname%.wav"
 
goto :eof

:settag
tag --removeid3v2 --genre 90 --album %podname% --title "%fname%" "%fpath%%fname%.mp3"
goto :eof


Feel free to use this script. Please share any changes with me to help make it better.

SSH private key login

Tuesday 31 of October, 2006
I wanted to configure sshd so that I could login without a password. I found a brief article at thinkholelabs (cache). While it has some other problems, the tutorial for authorized keys worked well.

After making this all work, I disallowed password logins using:
PasswordAuthentication no

The next thing is to enable some type of port knocking process.
Found this site (cache), and this DenyHosts script (cache) seems promising, but no time now.

Slackware 11 (part 3)

Saturday 07 of October, 2006
OK so we're cruising. I've configured the local samba settings so I can access my backup server. I copied over some scripts and am currently sync'ing data from my soon to be old server to the new.

While it copies I'll begin installing some of the basics.

* Installed 1.240 of webmin and upgraded internally to 1.30.
* Fixed the sound by installing the 2.6.17.13 modules and turning up the speaker volume :redface:
* Cleaned up lilo.conf so the smp kernel is the default and timeout is 10 seconds
* Started a sync of slackware-current and slackware-11 trees



Slackware 11 (part 2)

Saturday 07 of October, 2006
This morning I started cleanup of the problems listed above. Since I selected the huge26.s kernel, I need to load the modules for the 2.6.17.x modules. They are on disk2 in /extra/linux-2.6.17.13 directory. I loaded the linux-kernels-2.6.17.13.tgz package using 'installpkg linux-kernels-2.6.17.13.tgz'

I also edited /etc/lilo.conf to comment out vgs=790 and uncomment vga=791. I restarted. 'Ifconfig' reported the network problems are resolved, but I still have the video mode problem. Then I remembreed I didn't re-run 'lilo' after the lilo,conf edit. I did so, restarted again and that was resolved.

Next things - I have no sound (predicted by Pat V.) and my machine is only recognizing one core. (less /proc/cpuinfo shows only processor :0 info ) That's because this kernel is not SMP.
The sound will be solved by using a 2.4.x modules. I'm not sure how that works yet.
At this point, I'm going to switch to the 2.6.17.13-smp kernel

  • The kernel package is in /disk2/extra
  • copied the kernel, config and system.map file to /boot
  • created a link to system.map and config in the /boot directory
  • edit lilo.conf and added the new image
  • ran lilo to re-read the config

On reboot, I selected the smp kernel, but there were a bunch of errors about missing modules and the keyboard didn't work. So i restarted the hard way confused


I found the kernel modules in /disk2/extra/ and loded the kernel-module package. After reboot, I have two cores, and 2GB RAM

All goodness!



Slackware 11 Install

Friday 06 of October, 2006
I'm planning a Slackware 11 install and upgrade. I have new hardware (Dell GX620 Dual core, 2GB RAM, 250Gb SATA drive and the Intel 945 chipset.

My current system is an old Dell GX110, 1Ghz, 360MB RAM. I've installed quite a few packages over time. Here's my list

packageversion
TikiWiki1.9.4
Gallery2.x
WebCalendarCVS
phpGEDView3.3.8
PhpMyAdmin2.6.1
phpLDAPAdmin0.9.5
OpenLDAP2.3.20
OpenSSL
Nagios2.1
Webmin


I've downloaded the ISOs (hurray for bittorrent), burned them, printed and read the Readme, changes & hints and other pertinent docs from disk 1.

My next step is to boot from CD and partition the drive. I'm trying to find the best way to do that (yeah there are only guideline). I like using / & swap so that I can take advantage of one big disk, but I think there is benefit to segregating data from system.. Problem is I tend to store data in /var and custom programs in /usr/local so if I switch both out to their own partitions, I'm asking for future trouble. I think I'll go with the single partition for now.


Next decision was what FS to use. I read an article recently where SUSE dumped Reiserfs as the default format for disks. In reading their reasoning (basically, lack of developer interest), I've decided to use ext3 instead.)

Everything installed. I selected the huge26.s kernel and rebooted. I did receive an error on boot that an unsupported video mode was selected. I'll need to do some work in lilo.conf

I ran xorgsetup and started kde. After firing up Firefox it appears there is no network. Sure enough ifconfig shows only 'lo'

I need to copy some files from my backup PC. I've reconfigured smb.conf and started it, but at the moment it will not find the PC. Guess I'll come back in the morning.

Webcalendar

Thursday 21 of September, 2006
To prove mysql was working I installed webcalendar.

I copied the files over from uslacker and used <span style="font-style: italic;">phpmyadmin</span> to export the database.

I created a database (yes latin1_swedish is the correct collation) and imported the file that came from the export.

I had to change <span style="font-style: italic;">setting.php</span> to use <span style="font-style: italic;">user.php</span> and not <span style="font-style: italic;">user-ldap.php</span> since ldap is not currently running.

I managed to rememeber my non-ldap userid (Greg) and the password (sorry!)

All is well

Mysql install

Thursday 21 of September, 2006
Slackware-current uses Mysql5. I installed it and have had problems with the permissions. I re-ran muysql_install_db and reset the root password and all seems well.

Installed phpmyadmin 2.8.2.4 and then upgraded to 2.9.0 released today.


System upgrade

Thursday 21 of September, 2006
started the upgrade of this site onto new hardware. The new box has an Intel Core Duo w/2GB RAM. I built it with Slack 10.2 and upgraded to current. I'm awaiting 11.0 final before I complete the install. pat has just release RC5 so we're real close.


New system

Sunday 06 of August, 2006
I'm rebuilding on a Dell GX620, Pentium D Core Duo, 2GB RAM, 250GB SATA. Nice machine. I had some problems getting started.

  • Video recognition
When I went through xorgconfig, the xorg.conf that was created would not start. Final error was No screen found. I tried lots of things. Seems like there is a problem with the Intel 945 chipset. Whenever I specified the i810 driver, no glory.
I was using the default vesa driver, but it only recognized up to 1024x768 and my LCD needs 1280x1024.

I posted to LinuxQuestions and was asked to try xorgsetup instead. The conf file worked and all is swell. Here's the thread from LQ (cache)

  • Missing RAM
The machine has 2GB RAM but only 900+MB are recognized by the OS. Posted that to LQ as well. Apparently I need to recompile with Himem support. Thread here (cache)

My plan is to upgrade to -current. After that, I'll try both of these issues again.

Modifying tiki

Wednesday 28 of June, 2006
Modifying Tiki
Last month I signed up for a claimID account. ClaimID uses the concept of a microID to help you identify your web sites. microID site Claim ID site. I then went through the process of adding a claimID to each of the applications I use at www.gmartin.org (tikiwiki, WebCalendar, Gallery v2) so that my microID was part of the generated page. (this is somewhat invalid as I used the generic http://www.gmartin.org to generate the microID).

For the most part this was a trivial exercise. I found the header or footer template and made some changes. See my other blog post for the particulars.

What I want to do now is a couple things.
  1. The first is to adjust tikiwiki so that I can add new meta tage without regenerating the smarty template file
  2. Next, I'd like to add some code that actually generates the microID based on the page URL.

upgrading tiki

Monday 12 of June, 2006
Made some changes to tikiwiki and had to upgrade to v1.9.4. I had some problems

  1. The ldap login wasn't working. That turned out to be a global problem unrelated (ldap was down)
  2. The tikipedia theme was busted. I copied over the tikipedia directory in the ./styles directory, but forgot the tikipedia.css in the ./styles directory
  3. the bloglist plugin wasn't working. Had to copt it from /lib/wiki-plugins-dist to /lib/wiki-plugins
  4. my microid meta tag changes weren't there.


Adding MicroID info (or how to add meta tags to your apps)

Tuesday 30 of May, 2006
I grabbed a userid at www.claimid.com and wanted to add the microid meta tag to the pages of several apps I run - namely TikiWiki & Gallery. I figured this all out in under an hour, so your app may be different, but give it a try. One thing. This breaks a simple rule of microID - that the url is encrypted with the email addess. I used the site base URL (linux2.gmartin.org:82) for all pages. Since most of these apps only support static meta tags - that's where I wound up.

Here's how I did it:
The microid is a hash that is assigned to the url & email address combination for a particular page. The email address is the address on file at microid. The mID gets added to a meta tag in the page header. The following is the microID for

http://linux2.gmartin.org:82/gallery/albums.php
< meta name="microid" content="ccb852bd6c3bfce1414c1c950bada71584ade9ba" / >

I had to find the theme.tpl file corresponding to the theme I use (matrix) on the home page. I found it under ../gallery/themes/matrix/templates.

The instructions in the file say that in order to save edits across upgrades, not to edit the original files. I created a local directory (../gallery/themes/matrix/templates/local) and copied theme.tpl there. I edited the file with a text editor and modified the html to add the correct meta tag right before the line containing </head>
-------

For TikiWIki 1.10

This was much more involved, but simpler than v1.9.x. Tiki supports the use of meta tags. Problem is that they have a pre-defined set of tags and microID was not on of them. Take a look at http://.../tiki/tiki-admin.php?page=metatags

Edit /tiki/tiki-admin_includes_metatag.php and add these lines in the (isset($_REQUEST"metatags")) section:
simple_set_value('metatag_microid');

I added them after the author tag so they were clustered on the top of the page separate from the geo tags.

Next is to edit the header.tpl file in ./tiki/templates. In that file I added:
{if $metatag_author ne ''} &lt meta name="microID" content="{$metatag_microid}" /&gt
{/if}
Again, I copied the 'author' item and edited it.


Last is to edit ./tiki/templates directory to modify tiki-admin-include-metatags.tpl file. I copied the author line and changed the references to microid to match the other changes.
&lt tr &gt &lt td class="form" &gt {tr}Meta microID{/tr}: &lt /td &gt &lt td &gt &lt input type="text" name="metatag_microid" 
value="{$metatag_microid}" size="50" / &gt &lt /td &gt &lt /tr &gt

~/np~
Once this is done, you should be able to edit the microid tag on the admin/meta tags page. Once you save that and refresh, the tags should be on all pages in the site (not particularly accurate based on the microID concept, but it works for me!

For TikiWIki 1.92

This was much more involved. Tiki supports the use of meta tags. Problem is that they have a pre-defined set of tags and microID was not on of them. Take a look at http://.../tiki/tiki-admin.php?page=metatags

Edit /tiki/tiki-admin_includes_metatag.php and add these lines in the if (isset($_REQUEST) section:
$tikilib->set_preference('metatag_microid',$_REQUEST["metatag_microid"]);
$smarty->assign("metatag_microid",$_REQUEST["metatag_microid"]);

and this line in the else section:
$smarty->assign("metatag_microid",$tikilib->get_preference("metatag_microid",''));

I added them after the author tag so they were clustered on the top of the page separate from the geo tags.

Next is to edit the header.tpl file in ./tiki/templates. In that file I added:
[if $metatag_microid ne ''] &lt meta name="microid" content="{$metatag_microid}" / &gt
[/if]


Last is to edit ./tiki/templates directory to modify tiki-admin-include-metatags.tpl file. I copied the author line and changed the references to microid to match the other changes.

USB Mice & Slackware

Wednesday 28 of December, 2005
For Christmas I got this great IOGear MiniView Micro USB Plus 2-port KVM. Tonight I hooked it up to my Slackware server and had some problems with it recognizing the mouse now that it was connected via USB. My PC is an old Dell GX110 ~ 3 yrs old. It will work with a USB keyboard & mouse. I made sure USB EMulation was enabled in BIOS, but I am not sure it was necessary.

Within Slackware, I had to make the following changes

FromTo
File: /etc/rc.d/rc.gpm
/usr/sbin/gpm -m /dev/mouse -t ps2 /usr/sbin/gpm -m /dev/input/mice -t ps2
File: /etc/rc.d/rc.modules

File: /etc/X11/xorg.conf
Option "Protocol" "auto" Option "Protocol" "IMPS/2"
Option "Device" "/dev/mouse" Option "Device" "/dev/input/mice"




WebCalendar & LDAP

Saturday 05 of November, 2005
Upon further review, I flipped the setting $set_ldap_version to true in user-ldap.php

Here are the rest of my settings

$ldap_server = 'localhost';          

// Port LDAP listens on (default 389)        
$ldap_port = '389';                   

// Use TLS for the connection (not the same as ldaps://)
$ldap_start_tls = false;

// If you need to set LDAP_OPT_PROTOCOL_VERSION
$set_ldap_version = true;
$ldap_version = '3'; // (usually 3)

// base DN to search for users      
$ldap_base_dn = 'ou=people,dc=gmartin,dc=org';

// The ldap attribute used to find a user (login). 
// E.g., if you use cn,  your login might be "Jane Smith"
//       if you use uid, your login might be "jsmith"
$ldap_login_attr = 'uid';

// Account used to bind to the server and search for information. 
// This user must have the correct rights to perform search.
// If left empty the search will be made in anonymous.
//
// *** We do NOT recommend storing the root LDAP account info here ***
$ldap_admin_dn = 'cn=search,ou=people,dc=gmartin,dc=org';  // user DN
$ldap_admin_pwd = 'Search'; // user password


//------ Admin Group Settings ------//
//
// A group name (complete DN) to find users with admin rights
$ldap_admin_group_name = 'cn=webcalAdmin,ou=groups,dc=gmartin,dc=org';

// What type of group do we want (posixgroup, groupofnames, groupofuniquenames)
$ldap_admin_group_type = 'groupOfUniqueNames';

// The LDAP attribute used to store member of a group
$ldap_admin_group_attr = 'uniqueMember';


//------ LDAP Search Settings ------//
//
// LDAP filter to find a user list.
$ldap_user_filter = '(objectclass=person)';

// Attributes to fetch from LDAP and corresponding user variables in the
// application. Do change according to your LDAP Schema
$ldap_user_attr = array( 
  // LDAP attribute   //WebCalendar variable
  'uid',              //login
  'sn',               //lastname
  'givenname',        //firstname
  'cn',               //fullname
  'mail'              //email
);



Finally got this to work with LDAP. The problem was that Webcal wasn't making the transition to LDAP V3. I had to add:
ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, '3');
after if ( $ds ) { in function user_valid_login()
and in connect_and_bind()


For some reason, the variable $ldap_version doesn't work

LDAP Passwords

Saturday 05 of November, 2005
OK, I got slapd set up with password-hash {SSHA}. The tells slapd that all password are stored as {SSHA} hashes. I was able to encrypt the root password as well as several user passwords using phpLDAPAdmin

I was then able to authenticate within Tiki as an user. Don't know how to make groups work though


LDAP, Passwords, SSL & SASL

Friday 04 of November, 2005
I'm trying to do a simple thing - store non-cleartext passwords in OpenLDAP and use phpLDAPAdmin to set them. Long term I'll be using LDAP to authenticate for tikiwiki & webcalendar.

I'm trying to understand how passwords are stored then how to make use of them. It appears in slapd.conf, you can specify the default password hash mechanism or it defaults to SSHA. I'm trying to generate such a password and set it using LDAPPasswd. LDAPPasswd makes use of SASL.

So I've generated a certificate using OpenSSL and currently slapd is listening on port 636 & 389, however MyLDAPAdmin cannot connect using it. Not sure yet what that is about, but I suspect the cert isn't quite right

Auto login to the Linksys WRT54GS Parental Control

Sunday 02 of October, 2005
Auto login to the Linksys WRT54GS Parental Control

So we use the WRT54GS v2 for Parental Control. The PC software has a per user login that tracks what sites/IM/E-mail you use and restricts access based on time, site, user, etc. More can be found on the Linksys site (cache).

I have a Linux server that runs e-mail, a web site and keeps my dynamic dns up-to-date. in order for it to work, it must aleays be logged into parental control. Problem is that whenever the server or router is restarted, I have to manually log in the server so it can work. Until now. With the release of the 3.x and 4.x firmware, a new feature was added to allow you to "auto-login" particular PCs or gaming device. it took me 3 tech support chat sessions before I was able to convice Linksys tech support that the router now supported the feature (I had to read them the release notes!) and that they should find out how to do it. Here's what you do! (Thanks to Bryan Beals at Cisco for finally sending me the docs)

  • upgrade the router firmware to the latest version (currently 4.70.6)
  • Go to the Parental Control Support page (cache)
  • Reconnect your router (this is important - it will upgrade the version of firmware on file and allow you to get the new settings

Once this is done, you are ready to setup the PC to autologin

  • Get the MAC address for you PC. It will look like this 00:40:93:35:41:42 or this 00-40-92-35-41-47. You can get this address from the DHCP Clients table on your router if the client is currently connected and using DHCP (it is unless you've done something to stop it). That table is located at Status, Local Network, DHCP Clients Table.
  • Go Back to the Parental Control Support page. Click the Family Settings menu option.
  • Look for the hyperlink "here" text in the beginning of the instructions and click it:
"Click a family member's name to change their Internet privileges. Click here to automatically use a family member's privileges on a specific computer or device.

  • Enter a name for the device (e.g. XBox)
  • Enter the MAC address use the colon as a separator (e.g. 00:40:93:35:41:42). Note: There is a link to see the currently connected devices. Click "Show me the known devices", highlight the device you wish to use and click Move then Close
  • Pick the existing family member's setting that you wish to use. The device will always use the permissions of the familiy member you've chosen. You might consider creating a special family member for the device.
  • Click Add, then click Save.

That's it. Now the device you specified will always be logged in to Parental Controls.

AD, SSL & Load Balancing

Wednesday 04 of May, 2005
Interesting times. In previous posts we walked through some thoughts about how to create 3rd party certs that have the same CN so that the LDAP clients could see any server as though it were one.

We had created a cert request that had the cn set correctly, but AD/Win2k3 would not accept it since the domain controller name was not in the CN. The article from MS said we could put the dc name in the DNS name field of the Subject Alternative Name (SAN). We thought we had tried this. What we found is that you cannot specify a SAN with a retail cert from Verisign. We then signed up for the Verisign Managed PKI service.

We're still working through the results.


LDAP, SSL & Load balancing

Wednesday 20 of April, 2005
We need to configure two AD domain controllers/ldap servers behind a load balancer. The certificates for the servers (to allow ldaps) must have a common host name in order for the application server to see the correct cert when it connects.

For the Certs for the DCs we created the following Subjects:
Subject = "CN=AUTH.dom.ORG,OU=DomNTBZ07,O=DOM,C=US,S=state,L=city"

Note that the CN is the DNS name for the load balancer VIP.

The question is whether once the certs are installed whether AD will accept them as appropriate and enable ldap over SSL. We'll know soon

ssh config

Wednesday 20 of April, 2005
I realized the danger in having root access via ssh. I reconfigured sshd by editing /etc/ssh/sshd_config and adding the line: DenyUsers root.


Using a Verisign (or 3rd party) Certificate for AD Domain Controllers

Thursday 07 of April, 2005
If you are using a Microsoft CA, adding a cert to enable LDAP over SSL is a matter of simply installing the CA on a domain controller in the domain. The DCs all enroll automatically and you're done.

We've been struggling with how to add a 3rd party (Verisign) certificate to our Win2k3 AD domain controllers. Here's what we tried and what worked. If this helps you, please drop me a note at gmartinatgmartin.org

We first went to the MS knowledge base and found several articles. See the resoruces link below

They were mostly useless as few relate to Windows 2003. Particularly with how to generate the request. They refer to the Certificates snap-in. For whatever reason, you cannot generate a cert request using the snap-in. I believe it was tied to the MS CA.

The document with the real information is &lt;a href=&quot;http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/security/advcert.mspx&quot; target=&quot;_blank&quot;&gt;Advanced Certificate Enrollment and Management&lt;/a&gt;

Read that document then follow these steps:

Create the reqdccert.vbs vbscript on the domain controller file system
Run the script on the domain controller console (or in a terminal service session). (I did so without any command-line switches)
The following files get created:
Svrname-req.bat
Svrname-vfy.bat
Svrname.asn
Svrname.b64
Svrname.bin
Svrname.inf

We're most interested in the .inf file. Open it with notepad and the contents should look like this:
{CODE}
Version
Signature= &quot;$Windows NT$&quot;

NewRequest
KeySpec = 1
KeyLength = 1024
Exportable = TRUE
MachineKeySet = TRUE
SMIME = FALSE
PrivateKeyArchive = FALSE
UserProtected = FALSE
UseExistingKeySet = FALSE
ProviderName = &quot;Microsoft RSA SChannel Cryptographic Provider&quot;
ProviderType = 12

{CODE}

The section that says NewRequest. For Verisign, there must be a subject entry in this section and it must contain a lot of information. The subject we settled on looked like this:
Subject = &quot;CN=ourServerName.ourDomain.org,OU=IT,O=ourOrg,C=US,S=somState,L=someCity&quot;

Verisign requires the OU,O,C,S,L entries in order to generate the cert.
So make the changes and save the ifn file.

Now run the certreq -new svrname.inf svrname.req

The resulting .cer file can be used to request the certificate from Verisign.

Once you receive the cert back you import it using:

certutil -ACCEPT certfilename

Hope this helps.

Updating user accounts with DSMOD

Thursday 07 of April, 2005
We had to set the passwords for a bunch of accounts. DSMOD seemed appropriate since we had a list of DNs.

Here's what I did.
I saved the file as a CSV then replaced the commas delimiting the fields with colons. Using comma as the delim didn't work since DNs have commas.

Then the following command did the trick:
for /f "delims=: tokens=1-3" %a in (ETSNT60UsersToSetPasswords2.csv) do dsmod user %a -pwd %c

The for /f loops through the file specified in 'in (...)

The delims=: tells for that every colon delimits the next field

The tokens tells for how many items to pass once it has split the input line based on the delim

The %a is the name of the first token. Inour command %a %b & %c was set with DN, samaccoutname and password. The samaccount name was not need so the followin g command would have worked:

for /f "delims=: tokens=1,3" %a in (ETSNT60UsersToSetPasswords2.csv) do dsmod user %a -pwd %c
Note the change in token to pass just the first & 3rd token (DN & pwd).
