Can someone explain to me the rationale behind having ngroups_max set to 16 by default?
NFS only supports this much by default (from memory).
Samba (in the guise of Jeremy Allison)
has asked us to follow Linux's lead and support an arbitrary number of Groups
but it hasn't happened yet, Partly due to the question of "what to do about NFS" and partly just due to ENOTIME.
I just had to deal with this limitation and it was quite annoying to say the least, it appears Samba is somewhat deliberately designed to give you a hard time when you run into this limit, because as soon as you add a user to more than 16 groups it declares the group file unreadable and as a security measure shuts down all shares and authentication which wrecks a network which relies on Samba.
Also as far as I know Solaris and Linux has long gone past this limitation.
