After the upgrade form 1.0.1 tot 1.1 some users "lost" one specific netfolder (the complete folder not a subfolder).
File rights are give by a AD group.
All the other users whitin this group still see the netfolder.
There are no changes at AD file rights or group memberships.

Users have access to the folder using the drive mapping at there client.

Taken actions:
- checked groupmembership in Filr
- removed and added the security group in the Netfolder config.
- removed user form Filr and recreated him through the ldap sync.
- checked the Famt and Filr log at the Filr Appliance no error's to this user or folder

Any idea for throubleshooting?
