>> This is news to me, I thought the underlying ngroups_max setting would be the limiting factor???
Does this mean that Samba 3.0.2a does not have this limit? Is this only when using winbind or does
Samba circumvent this restriction even when using files/NIS/LDAP for storing user & group data?
Be very interested to understand this if someone can take the time to explain,

		thanks Andy.

Upgraded our Solaris 8 and 9 servers from 3.0.2a to 3.0.3.

After upgrading any user that was in more than 16 Unix groups wasn't able to 
map any drives.  I get this error in the log file:

[2004/05/04 12:23:30, 0] auth/auth_util.c:get_user_groups(695)
  get_user_groups: failed to get the unix group list
[2004/05/04 12:23:30, 0] auth/auth_sam.c:check_sam_security(260)
  check_sam_security: make_server_info_sam() failed with 'NT_STATUS_NO_SUCH_USER'

I tried increasing the kernel parameter ngroups_max from 16 to 32.  I was able 
to map drives, but this breaks NFS.

Any idea what has changed from 3.0.2a to 3.0.3?  Is it a know bug?
