I was digging through the logs after sending that to you, and spotted 
the above. ;)

Now this one is interesting. The user "does" exist.
If I do "id u212442" on the server, it produces the appropriate user 
id/group...
#> id u212442
uid=1040(u212442) gid=1001(sysadmin)

So the user does exist. But for some strange reason (which I still 
don't understand), it doesn't report that to Samba at login time.

>I'm CC:ing to the list so people can see the resolution of this issue.

Sorry to say, that it's not resolved yet. I think we've found the 
symptom, but not the cause.
If the user exists, why doesn't samba see it?

All of the assistance on this is greatly appreciated!
