Rightsattribute missing or bugged

Hello all,

I am having a hard time managing rights for the webinterface. I have just enabled AD logins via LDAP. There is CN which I’ll just name ‘admins’. Members of admins should be able to do a bunch of stuff which works fine except that I am not able to grant the the right to browse backups under the tab ‘Backups’. They can only see the backups of their own machine. Even granting them ‘all’ has not resolved the problem. Is there a secret attribute I am not seeing?

Regards

*Edit 1: Note that local admin users (such as default ‘admin’) can access all backups.
