To use a ProxySG authentication realm to access the Management Console you must create rules for "Admin Authentication Layer" and " Admin Access Layer" in the Visual Policy Manager (VPM).
" Admin Authentication Layer"
Source : Any
Action: Set -> New -> Authenticate ( Add Authentication Object : Name - AdminAuthenticate, Realm - LDAP, IWA or other Authentication realm)
Track : None
"Admin Access Layer"
Source: Set --> New --> User (Add User Object : Authentication Realm- Same as above layer, User - Browse for respective Authentication Realm)
Action: Read/Write Access(as per requirement)
This will allow the non-admin users to access the ProxySG Management Console using their Authentication realm credentials. This has been tested for LDAP and IWA Authentication Realms. It is useful for security purposes.
