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?

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.

Can you tell me the cause of this issue?
