As anyone who is familiar with NFS is aware, auth_sys has a limit of members=
hip in 16 aux groups.

In today's "everything is in AD universe" it's incredibly common for an acco=
unt to be in more than 16 groups.

There are various solutions to this. Right now the only reasonable one on Fre=
eBSD is to use Kerberos. auth_krb does not have the 16 group membership limi=
t. Of course that solution is great if you already use Kerberos, but if you d=
on't suggesting that as a solution does't always go over so well.

The Linux crowd extended their NFS server years ago with a --manage-gids opt=
ion that lets it ignore the group member ship sent over the wire by the clie=
nt and look up group membership locally.

Does anyone have any objections to that option getting ported to FreeBSD?

Thanks,
