samba - Jul 2011 - Samba -> PANIC: sys_setgroups failed

Hi,

Hope someone out there can help me on this Samba issue. I'm running out of
ideas, I spent days on Google but still have not find any solution yet. Finally,
I got Samba 3.5.9 acts like it works, giving me data with wbinfo -u and wbinfo
-g AND it returnsusers in my Active Directory with getent passwd & getent
group. However, if I try to connect to samba server from windows machines,  it
fails and gives me the following error in the log file:

Here is my smb.conf...

[global]
        workgroup = MYDOMAIN
        realm = MYDOMAIN.COM
        preferred master = no
        server string = Samba %v - %h
        security = ADS
        encrypt passwords = yes

        inherit acls = Yes
        debug level = 0
        log file = /var/log/smb.log

        winbind enum users = no
        winbind enum groups = no
        winbind use default domain = Yes
        winbind nested groups = Yes
        winbind separator = +
        idmap uid = 10000-20000
        idmap gid = 10000-20000
        ;template primary group = "Domain Users"

Please help. Thanks a lot in advance.

Anh.

Are you running on Solaris or AIX maybe? It might be that
you are running into the limit of at most 16 groups per
user.
