Error installing Windows Services for Unix 3.5


I'm trying to install Windows Services for Unix 3.5 on my 2003 Domain Controller.  I've pasted the install log file below (it's only a few lines).

Just to check I'm on the right track, I was hoping WSFU would do away with the need for me to maintain 2 sets of user accounts (one for Windows and one for Unix).

Anyway, log file below.  Any ideas?

Many thanks,

Checking SFU schema version
Existing Services For Unix Schema Version - 30.

Checking SFU V30 schema on server - server.mydomain.tld
Verifying all extended schema attributes. AD Server = 'server.mydomain.tld'.

    Could not find schema attribute on this DC. Attribute = 'msSFU-30-Uid-Number'.

Checking existing SFU configuration version
Higher schema version already installed.Version Installed: 40

Error: The operation completed successfully.

Current Config Version = 40

SFU Schema Extension did not complete.
End of schema extension. Time: Tue Apr  3 01:05:01 2007

Are you running on Windows Server 2003 R2?  If so, the SFU schema is already there.

You can install and use NIS for UNIX authentication, but that has its own security problems...
