Permission denied on already mounted nfs share

[mmerlone]

Greetings.

I have a FreeNAS server exporting a volume /mnt/FOO to a Ubuntu 10.04 LTS server, which is NFS mounted OK at /mnt/foo. Both FreeNAS and Ubuntu uses the same LDAP server for auth.

Most users don't have problems cd'ing into dirs and writing files. But there is (for now) one group 'bar' with a problem. When a user belonging to group 'bar' try cd to ubuntu:/mnt/foo/folder it gets permission denied. On FreeNAS shell, the same user is able to cd into this folder and write files. Both boxes reports the same for `id user`, user and groups ids match.

This is in production for a 100+ users network, and thus is a burning issue. Thanks in advance for any help.

Found this, which looks exactly the problem:
https://xkyle.com/solving-the-nfs-16-group-limit-problem/
Now, seems mountd on FreeBSD does not have the -g switch. Any hint?

In FreeBSD, it is mount_nfs: http://www.manpages.info/freebsd/mount_nfs.8.html.

Hi,

Nice reading, but it does not offer a solution to the 16-group limit over NFS, which on linux is the '-g' switch. That was the hint I was asking for. Thank you for the doc though.

Regards.
