[Samba] Group membership limitation

2005-10-28 Thread Bruno Guerreiro
Hi all.
I've made this question over and over, but still no answer till now.
So here goes again, maybe I have better luck this time.
Is there any limitation to the number of groups a samba user may belong?
I've found out that if the user belongs to more than 60 to 70 groups,
group-based share access stop working. 
From another post in this ml, i've found out that kernel 2.4.xx had a 32
group membership limitation, but i'm using 2.6.xx which has a 65536 groups
limit.
Is there any place in samba where I shoulb be looking?
Any info/pointers would be much appreciated.

Fedora Core 2 with:
Samba-3.0.14a
Ldap backend with openldap-2.2.13-2

Best regards,
Bruno Guerreiro

Have you check with getent command if your platform response correctly?
try getent group GROUP_WITH_A_LOT_OF_USERS_FROM_YOUR_LDAP_BACKEND
It should returns a members list like a line from /etc/group.

If it does not work, check your entry in nsswitch.conf and replace
passwd compat by passwd ldap (do the same for the group and maybe
for shadow)

Another thing you could try is use the recently ldapsam:trusted = yes
option... take care of the considerations to make it work!


Saludos,
