SMB Share with AD Permissions

We recently deployed the SUSE Enterprise Storage with Ceph filesystem and have been able to export it as SMB shares and connect it to our Windows AD. The permissions work partially. However, when we modify the permissions of the folders within the share to give access to specific User Groups (custom groups) in Windows AD the user of the group is not able to access the folder. The user gets the access denied message though he is part of the user group in AD. The only User group that works is the Built-in Domain Users group. Any help on this would be appreciated.
