I am looking at the AM 5.5 transactional authz conditions and wanting to use the Auth Level Authentication Strategy. I am wondering what the valid Strategy Specifier is for that. I understand that when you do any of the other Authentication strategies, the user will need to authenticate to the specified chain/realm/tree/module, but what about the Auth Level. Is the Auth Level strategy an equal or a greater than condition? Can it be an expression or just a number?
