Directory and Authentication / Samba Shares "Access Denied"

« on: December 23, 2015, 12:59:18 am »

After upgrading a 3.2 on Ubuntu 12.04 to 4.2 on 14.04 I'm having share permissions issues.  I've tracked it down to the fact that the /home/samba and other folders created by samba have gid of 1901 and smbd is not able to cd into the directory because it's running as the user who connected.

I am able to query ldap for users and groups with getent but I cannot find __USERS__ or a group with the ID 1901.

I'm wondering how to recreate the __USERS__ group in the directory and what gid should it have?

Also, how does samba decide what uid & gid to use when a new connection is made from a client?

Am I on the right path here? what else can I show to help get this resolved.
