[Samba] ldapsam + IE7 = Broken MS Office 2003/2007

[Koji Yanagisawa]

Dear Samba people,

I'm pretty stumped troubleshooting this odd behavior by Microsoft Office 
2003/2007 where if I allow the machine to upgrade from Internet Explorer 
6 to 7, Office breaks.  Users usually get either "Word could not create 
the work file. Check the temp environment variable" or simply not able 
to save.

The same machine with IE7 works fine for local users, or when Samba uses 
tdbsam.  Normal Office troubleshooting has yielded nothing.

Freshly configuring Samba with LDAP results in the same problem.  I've 
tried 2 different servers (RHEL3 and CentOS5) and 2 clients to the same 
end.  Local administrative rights have no effect.

I understand the question might sound kind of vague, but has anybody run 
into this before?  Am I missing something?

Thank you,
