SFU error message on NIS Server node

[Demel]

I have problems with identity management for unix, the problem is the one
described in kb article 923515.
The serverReference attribute value on the server is correct.

Also password synchronization does not work.
When i make a password change, the attribute unixUserPassword remains the same
i have tested all the configuration settings in a test environment and it
works.
All the DC in the domain have Password Synchronization installed and enabled.
The tool is running on a windows server 2003 R2 AD DC.

I'd like to hear from others before I contact Microsoft Customer Service and
Support.

Copy and save the text between <code> and </code> as servref.vbs and
run it using the following syntax -

c:\>cscript servref.vbs -all

This will list all the servers that need to have serverReference
populated with their DNs. If you see any servers with blank
serverReference - you will have to fix them before this error will go
away.

Hi Ashish,
when I run the the script, I get the following output:
Microsoft (R) Windows Script Host Version 5.6
Copyright (C) Microsoft Corporation 1996-2001. All rights reserved.

Configuration='CN=Configuration,DC=domainname,DC=com'

Query='<LDAP://CN=Sites,CN=Configuration,DC=domainname,DC=com>;(objectClass=Server);name,distinguishedName,serverReference;subTree'

Done.

Thank you Ashish. You helped me dig a little bit further into the problem.

After reproducing the whole thing on a copy of the actual production
environment and modifying the script to show all the servers with or without
a value in serverReference, it showed exchange servers without a value in the
serverReference attribute. (Why it didn’t show these servers before
modifying the script, I don’t now). Why are the exchange servers listed
under my Sites Servers? Maybe because we have an application installed that
uses Microsoft Message Queuing.

I added the value for serverReference attribute for these servers and voila,
the error message was gone.
The serverReference attribute value MUST be populated for ALL the servers in
the Sites container. The statement “This problem occurs when the
serverReference attribute has a value of <Not Set> for a particular Server
for NIS network in Active Directory Configuration container”, in KB 923515 is
not clear and incomplete. It should reference all the servers within the
(adsiedit.msc) Configuration[<ServerName>.<YourDomain>.<DomainSuffix>],
CN=Configuration,DC=<YourDomain>,DC=<DomainSuffix>, CN=Sites Sites container.

My first problem is resolved. Now I still have the password synchronization
problem.
All the DC in the domain have Password Synchronization installed, enabled
and are configured as follows.
“Windows to Computers that run on UNIX” is enabled.
“Port Number” 6677
“Encryption / Decryption key” is the same on all DCs.
“Enable extensive logging” is enabled.
“Enable Windows to NIS (AD) Password Sync” is enabled.

UNIX Computers container is empty (as it is in the test environment, where
it works).

Here is my solution for the password synchronization problem!

Uninstall idMU
Reboot
Search for (psxdll.dll, psxdllsvr.dll, psxrun.exe, psxss.exe, pswdsync.dll,
psxdrv.sys) and delete files
In the registry, search for idmu and delete all references in registry
Install idmu
Reboot
Set Server for NIS service to automatic and start service
In password synchronization properties, configuration tab, enable extensive
logging and enable windows to NIS(AD) password synchronization
Select NO for "perform compatibility check"
Select YES for "are you sure you still want to enable this feature?"
At the command prompt, ypmatch -d <NIS Domain> <user> passwd.byname, to
check the current password
Change test user password and check for event id 4098
In Identity Management for UNIX, Server for NIS, click check for updates now
At the command prompt, ypmatch -d <NIS Domain> <user> passwd.byname, to see
if the password changed
In password synchronization properties, settings tab, generate a new key (or
copy the generated key from another DC)
