I cannot see “Unix attribute” tab even after installing IdMU – Windows Server 2012 R2

You cannot see the Unix Attributes tab in Active Directory on Windows Server 2012 R2 even when you install IdMU. You tried to re run the PowerShell commands to enable these features and the Unix Attributes tab is still not showing up. Apparently this can happen for two reasons:

  • nisprop.dll is not properly registered
  • adminPropertyPages attribute is not properly populated

In case this is your issue, you can very easily register the nisprop.dll and the Unix Attributes tab will appear again.

cd c:\Windows\idmu\common
regsvr32.exe /u nisprop.dll
regsvr32.exe nisprop.dll

As well this command line works in order to fix this issue

# Unregister nisprop.dll
regsvr32.exe /u C:\Windows\WinSxS\amd64_microsoft-windows-rsat-server-for-nis_31bf3856ad364e35_6.3.9600.16384_none_c8d5e04e336a0267\nisprop.dll

# Register nisprop.dll
regsvr32.exe C:\Windows\WinSxS\amd64_microsoft-windows-rsat-server-for-nis_31bf3856ad364e35_6.3.9600.16384_none_c8d5e04e336a0267\nisprop.dll



Once you have executed the commands and successfully registered the nisprop.dll on the Windows Server 2012 R2 – the Unix attributes tab is appearing back in Active Directory as before. Also there exist another interesting scenario with this Unix Attributes and how to fix it – check the KB921913
