[Samba] username map problem

[Jamie Bohr]

I am using Samba 3.0.23a-1 and am having issues with the "username map"
option.  I copies my map that works for Samba 2.2.8 to a system running
Samba 3, no good.  I googled around and have come up short.  Users whose
Windows account names match their UNIX account names can use the shares,
this affects only users whose account names do NOT match.  The error I get
is "session setup failed: NT_STATUS_LOGON_FAILURE".  Can someone point me in
a direction where I can find the answer?

Thank you,
