[Samba] Can't add users to an ACL

[Nathan Friess]

Hello all,

I have the following setup:

- Linux server running Debian stable
- Custom kernel, 2.4.24 + ext3 ACL patch 0.8.64
- Samba 3.0.1-3 from binaries at samba.org, setup as a PDC, using the
smbpasswd backend

I have ACLs working with both setfacl and smbcacls.  I can view ACLs and
change permissions of users already in the ACL of a file on the server using
a Windows XP client.  However, when I try to add a user, after giving
Windows the name of a valid user, it prompts me for a username/password.  If
I give it a user/pass, it says that I can't have two connections at once (no
matter if I use my current user/pass, or another one such as an admin
account), and Windows can't find the user.

I turned up the debugging level, and I saw nothing suspicious (errors and
the like).  However, the last thing that happened before the final LSA_CLOSE
requests was an LSA_ENUMTRUSTDOM which responded with
NT_STATUS_NO_MORE_ENTRIES.  I'm not sure if that's normal or not, but that
seems to be the point where Windows stops trying to lookup the user.

Does anyone know what could be the cause of this, or what else I can look
for to diagnose this problem?

Thank you,

Nathan Friess
