reversing domain and user name?

[David Edward Shapiro]

I can get authentication to work on linux 7.1 with samba 3.0alpha15 if I
make valid users = @"INS+Domain Users", but if I try to set valid users to
just a single user:

valid users = INS+DavidSha, it fails to give me access.  I see the following
in log.winbindd.  It looks like it is looking for a domain called
DavidSha?!?  My winbindd separator is +.  Can somebody please respond to
this.

2002/02/20 11:37:21, 3] nsswitch/winbindd_sid.c:winbindd_lookupname(76)
  [27055]: lookupname [DavidSha]\[INS]
[2002/02/20 11:37:21, 0] nsswitch/winbindd_sid.c:winbindd_lookupname(83)
  could not find domain entry for domain DavidSha

wbinfo -t secret is good
wbinfo -u/-g returns all groups/users
getent passwd INS+DavidSha returns a user line
getent group "INS+Domain Users" returns a group line
