[Samba] Winbind not mapping new user groups

[Mark Irving]

Problem: When a user is added to a group on the W2K3, the group is not
mapped to the user on the Samba server. 

System: FreeBSD 5.2.1-RELEASE #0: Mon Feb 23 20:45:55 GMT 2004 
Network: Windows 2003 (no SP1) AD
Samba Version: Version 3.0.14a
Security = ads
Kerberos: heimdal-0.6.3_2 
Diagnosis: Winbind log shows the following errors:
	     nsswitch/winbindd_user.c:winbindd_getpwuid(238) could not
convert uid 10143 to SID
	     wbinfo -r username doesn't show the uid of the new group
More info: Samba running on another machine with the same BSD release,
heimdal and Samba versions does not exhibit the same problems
Troubleshooting: I removed the winbind.tdb files and restarted Samba and
then reset the permissions on the files. This had no effect.

Any ideas?
