security = domain & security = user mixing.... Is it possible?

[Rolando Berrios]

Hey all,

I've read through the documentation and (unless I'm an idiot) I can't find
a resolution to this problem.  I'm trying to move from a workstation style
setting, using pretty much only NT desktop machines, to a NT domain style
network.

The problem is that we have a few people who won't be joining the domain
and will need to access the SAMBA shared (file/print)server that is
running in the security = domain setting.  After wondering to myself why
the users weren't able to log onto the Linux box running SAMBA, I tried
looking at the log files and I got this:

.....[snip]
[1999/04/28 17:11:33, 0] rpc_client/cli_netlogon.c:cli_net_sam_logon(371)
  cli_net_sam_logon: NT_STATUS_NO_SUCH_USER
[1999/04/28 17:11:33, 0] smbd/password.c:domain_client_validate(1365)
  domain_client_validate: unable to validate password for user rberrios in
domain NT-TESTDOMAIN to Domain controller TESTDOMAINCONTROLLER. Error was 
NT_STATUS_NO_SUCH_USER.
.....[snip]

After that it attempted to find the user on the SAMBA server in the
smb_passwd file, of which there was no such user.

When I try to connect to an NT server that's part of the domain and the
account I'm using is not a domain account, but a local one, I don't run
into any errors - I simply have to enter the domain account username and
password pair and I'm in.  

Is this functionality not supported?  Or are there some configuration
options that I've screwed up?  

Any help would be very much appreciated.
