This one may need to remain a mystery.  I went show the SID differences
to a colleague 4 hours after sending the original post and the symptom
had disappeared.  I had changed the uid / gid ranges from 10000-20000 to
1000-200000 but even after changing them back I have not been able to
repeat the issue.

I'll post again if this happens again.  Since this is my first samba
server it is still in lab status and I will leave the log level set to
10.  Maybe I'll catch something.
The log you ask for does not show anything to me that is abnormal but
here it is:

[2005/02/02 07:43:43, 1] nsswitch/winbindd.c:main(864)
