[Samba] WINBIND: only 88 group members ?

[Dr. Matthias Schlett (987)]

I'm trying to get the WINBIND 3.0.10 on a AIX5.2 machine working in our 1200 users
environment.
We have some groups with more than 100 users, these are not recognized by WINBIND.
The ldap server deliveres the  needed entry, but it seems that the entry is too long for WINBIND.
I found that the maximum number of group members is 88.
How can I increase this  maximum ?

Regards
