[Samba] smb_panic sys_setgroups failed
Hi, We have Samba version 3.5.4 and we are using winbind (Active Directory) for authorisation. The issue is that for most of the members of a Samba share it is not possible to connect this Samba share. This because of the error below. It seems to be that the number of Active Directory groups where this Samba member belongs to is too high. UNIX token of user 588109 Primary group is 10049 and contains 188 supplementary groups [2010/10/04 14:12:22.682600, 0] lib/util.c:1465(smb_panic) PANIC (pid 14999610): sys_setgroups failed [2010/10/04 14:12:22.682922, 0] lib/util.c:1619(log_stack_trace) unable to produce a stack trace on this platform [2010/10/04 14:12:22.683121, 0] lib/fault.c:326(dump_core) dumping core in /opt/pware64/var/cores/smbd [2010/10/04 14:12:22.740533, 3] smbd/server.c:259(remove_child_pid) smbd/server.c:259 Unclean shutdown of pid 14999610 [2010/10/04 14:12:22.740965, 1] smbd/server.c:267(remove_child_pid) Scheduled cleanup of brl and lock database after unclean shutdown Can you tell me the cause of this issue?

What OS?
I am running Solaris 10 machines with Samba 3.4.x and 3.0.x
Samba 3.4.x (and presumably 3.5.x) checks to see how many windows groups
the user belongs to. It checks what the max number of groups a user is
allowed to belong to by the unix syste. If the windows group list
exceeds this maximum you will have problems. On Solaris, this is the
"ngroup_max" kernel parameter. By default it is 16 (this is for
backwards compatibility with NFS + RPC authentication.)
You can increase the limit by editing the /etc/system file and
rebooting- e.g.
set ngroups_max=32
This can break NFS mounts if the user is in more than 16 groups.
Which may not be an issue.
I don't know if there is an equivalent setting in Linux, of if linux
even has such a setting.
How is a user in 188 groups?
