samba - Apr 2011 - Problems with Squid and Active Directory

Hello!



Since a few weeks I have Squid Version 2.7.STABLE7 on Ubuntu Server 10.04. All
worked fine - different users in an AD-Group could reach the internet through my
proxy. Because of this my Squid-configuration seems to be OK. Since the name of
the AD-Group was changed it is no more possible to reach the internet through
the proxy. The error is:

"Access control configuration prevents your request from being allowed at
this time."



Switching to the old group name all works fine again, switching to the new one:
the same error as above.



I changed the debug options and found this entry in cache.log:

"Could not convert sid S-1-5-21-3365863304-72330373-946326852-415981 to
gid"


>From the Squid Mailing List I got the answer that this is a problem of Samba
and/or winbind.
I have installed:

samba  2:3.4.7~dfsg-1ubuntu3.5

winbind 2:3.4.7~dfsg-1ubuntu3.5



What to do?


Thanks!
