>You are accessing clearcase on UNIX right?
Yes we will be.  But not right now.  Since ClearCase will not support Unix 
clients from a Windows VOB server, we started with a Linux Server even though 
our first clients are all windows.

>Not through Samba.
No, we are using Samba in addition to WinBind.  I am fuzzy on why ClearCase 
needs Samba in addition to it's own stuff.  I think that is how the Windows 
View Server talks to the Unix VOB Server.

>You need winbindd so that Windows domain users can have a UNIX account
>and access the respoitory on the UNIX server.  Right?
Yes that is correct.

Most sites can control the primary windows group users get for any Domain.  We 
can add users to a clearcase group, but can't make it the user's primary 
group.  clearcase has a patch to get around it under Windows.  They use a 
special environment variable.

I limited the "winbind primary group" so it would only set the primary group 
if the user is actually a member of the group in the first place.  But this 
can be overridden with the "winbind force primary".  The primary group value 
is a RID and *not* a Unix GID.

I suspect if I use Andrew's suggestion and set g+s on the directories it may 
work, and this has worked for me in the past when using NFS & NIS+.  But one 
of the first questions on the pre-techsupport droid's check list is "type 'id' 
and read me your default user group...".

This default group thing has *never* been a problem for me under Unix.

Once I applied the patch, clearcase started working like a charm.
