User Defined Functions: This policy is by design ambiguous in terms of how it may be implemented. The premise of this panel is to provide support for applications that are dependent on "Role Based Security". Implementing a UDF policy will set a session variable to either true or false for each client.
If the UDF policy is applied to a user account or group, when that user logs into the system, the session name will be set to true. Otherwise the session variable will be set to false. This method will provide adequate support for adopting a required role based security when necessary.
