Hey Rowland,

Thank you so much for your help and patience.

OK, just a few questions based on what is in your smb.conf, which seems to

That's consistent with my understanding.

passdb backend = ldapsam:"ldap://hosturl"

Yeah, sorry. I anonymized some of the parameters in order to (hopefully)
comply with policy. I'll take this opportunity to apologize for all past
and future clumsiness.

> ldap suffix = o=org
> Is this correct ?? I would expect something like 'dc=example,dc=com'

Actually, yes. Moreover, there is no line of the form 'dc=example,dc=com'
anywhere in the file.

> unix password sync = no
> This means that there is no sync between samba and local unix users i.e.

Yeah, that directive is brutally intuitive; it's funny what total
intellectual disorientation causes me to view with suspicion. I was
thinking that it was possible that some other directive might have a side
effect that overrides the 'unix password sync' directive.

I don't believe that there is a NIS home directory server running. I've
replaced "logon home = \\%N\%U" with "logon home = \\%L\%U"; thanks for the

Got it.

Ah. Ok, I think I understand, sort of. However I'm still required to
authenticate using the user's Samba password (set via smbpasswd) in order
to view the shares. Is that consistent with the user being mapped to nobody?

I'm also still unclear on why Samba doesn't see the user; the user appears
in the list generated by 'pdbedit -L', for instance. What gives?

Thanks again for your help!
