samba - Feb 2005 - Samba 3.0 question, DOMAIN vs. SERVER method? Help!

Hello all!

We are attempting to get Samba-3.0.10 working on a new Solaris 8 machine in
preparation for upgrading an existing 2.2.8 installation (both use the
SMCsamba packages from SunFreeware.com).  We copied over the smb.conf file
and the usermap from the Samba-2 installation, and seeing some weird
symptoms when Windows users try to connect to the new machine.

We ran "net join" to join the local domain (referred to hereafter as
MYDOMAIN).  When we set "security = DOMAIN" in the smb.conf file
(which is
how we have it on 2.2.8), it works for users that are not in the usermap
(i.e. whose UNIX login name is the same as their Windows login).  But users
who are in the usermap can't connect.  However, when we change the setting
to "security = SERVER" then it works for the users in the usermap.

The main difference I see between DOMAIN and SERVER logins is that the
DOMAIN uses winbind authentication, while SERVER uses smbserver
authentication.  Also, it looks like Samba tries to create a user with the
login of the UNIX user, and then fails because it can't.

If anyone can tell me where we're going wrong, I would really appreciate it!
Thanks in advance!
