[Samba] username map

[JESSE CARROLL]

Forgive me for being new - but you've got start somewhere.

I've setup SAMBA on a Unix server that talks to AD. Almost everything works
save for a user name map. From my configuration (names changed)below I can
attach from windusr1 on PC1 to the Unix system and it sets up as unxusr1 no
problems and clean. I can access all three shares. However, when I try to do
the same thing from PC2 for appusrwin I am prompted for a name/password. No
matter what I put in (windows ID/password or Unix ID/password, or combinations
of these)I can't connect. The message in the log.smbd is
"domain_client_validate: unable to validate password for user appusru in
domain XXXGLOBAL to Domain controller USORSDC00. Error was
NT_STATUS_NO_SUCH_USER."  Note that in reality the Unix ID and Windows are
very similar, with the difference being that the Windows ID is the same as the
Unix ID but with 2 more characters.  What am I doing incorrectly?
