[Samba] User groups

[Cybionet]

Wlcome in the club :-)

I wrote a topic "Limit of group membership for a user?" with the same 
problem, and I don't have any answer by the samba team. I have the most 
recent Samba 3.0.21b, OpenLDAP 2.2.28 and Glibc 2.3.6 version on a 
Gentoo (kernel 2.6.15) and I have the same problem. I check the 
NGROUP_MAX (65535) and the NSS_BUFLEN_GROUP (2048) value of the glibc.

For the AMD64 environment I have a limit of 66 groups for a user, but 
suprise, on the x86 environment I stop to count at 83 groups for a user 
(but it is not the limit). I continu the test this week.
