Abstract
Disclosed is a method for transitioning access rights, in a remote station with role-based access control, for an unknown role having access rights defined by a central access control management module. In the method, a role capability table is maintained in the remote station specifying centrally-defined access rights of roles that are interpretable in the remote station. An access request associated with an unknown role that is not interpretable in the remote station is received. The access request includes a role transition list that relates the unknown role to other centrally-defined roles. At least one of the other centrally-defined roles is interpretable in the remote station. A role is selected, from the role transition list, that is interpretable in the remote station for interpreting the unknown role of the access request. Access is granted based on the access request associated with the unknown role using the access rights of the interpretable role selected from the role transition table.
