[Samba] smbpasswd

[Ric Tibbetts]

All;
I have, what should be a simple install, that is "stuck".

I need to set this up, very simply to authenticate the windows user 
coming in, and present the shares, NOT requiring a password.
I've tried everything I can think of, but it always prompts for a password.
If I put the user in smbpasswd, they can log on, but it requires an 
initial passwrd (only the first time, then never again). But... I've 
built servers in the past that did not require the users to be in 
smbpasswd, a valid, matching, unix password was sufficient.

If I put
security = DOMAIN
in smb.conf, it will ALWAYS prompt for a passwrd.
If I put:
security = USER
it prompts once, but the user has to exist as a unix account, AND in smbpaswd.

How do I get around this?
I've done it on other servers, in other places, with no problem. But 
this one is hanging me up.
I could use a pointer.

Thanks!
