Initgroups errors.on OSX with WinXP

[The DJ]

Oke, I patched it too use unknown, now the message about the problem with
the groups disappears, but the initgroups still fails.

Group unknown has id 31
User unknown has id 99
Group admin has id 80

Here is part of a level 10 debug.
Of me accessing my guestshare from smbclient.
Can someone clarify to me what is going on here?
