I don't believe that's true; winbind serves functions *other* than just
the nss and pam modules. This is a common problem, and more
documentation related. The issue as I explained it to a colleague is:
Winbind thinks the user is "DOMAIN\user", can't find that in the
existing "password" database (be it files, NIS, or LDAP) and allocates a
I think the poster wants the:
winbind trusted domains only = yes
...parameter. I'm assuming he's got:
userA (same user as DOMAIN1\userA)
userB (same user as DOMAIN2\userB)
The winbind parameter above makes this setup work correctly, and
arguably should be the default since I'm assuming if it *fails* to find
the UID in the password it'll still allocate a UID.
[Checks; Hmm. No, it doesn't]
Incidentally, I would have thought "winbind use default domain = yes"
would also be required *if* the nss and pam modules were being used e.g.
for SSH/FTP etc.
Finally, I found I needed to delete the winbind.*.tdb files to make this
change "work" - is this expected?
Of course, if his NIS users have different names than the windows users
he will *also* need the "username map", as you pointed out.

I think it should map windows accounts with the same Unix accounts. If the Unix account is different from windows then it should check static mapping file. Same for the groups mapping too.
