Brent Shank has started a site to compile information on running Samba on MacOS X Server.
Here is the message he posted to the MacOS X Server mailing list:
I've started to compile a web site of Samba and Mac OS X Server
information. It is by no means complete, but it currently does include
info on how to set Samba up on OS X to authenticate to an NT domain.
This includes updating the NetInfo database using niload and converting
NT user names to be compatible with the passwd file format.
I would appreciate any ideas for additions and correction to the page.
Thanks,
-Brent
