samba - May 2002 - Unresolved SIDs when setting ACLs

Hi!

Using the 2.2.4-release, I have some problems setting the appropriate
ACLs for a user.

[2002/05/17 13:54:04, 0] smbd/posix_acls.c:create_canon_ace_lists(775) 
create_canon_ace_lists: unable to map SID  S-1-5-21-1592022623-3701810705-35715
25119-3003 to uid or gid.

When trying to set new ACLs for a user, the above message appears.
