Samba server (V3.25)runs on Debian Lenny (Kernel 2.6.26) as a member
server in an AD domain, DC is a Windows 2003 server.
Everything works fine, only one group (exactly one!) isn't seen by
getent group. It is listed by wbinfo -g.
I know the issues about to much groups in an AD domain and timeouts, but
the total numbers of groups is between 150-180, and it is always one
group, which is listed or not. The name of the group is 'mail_user'
