NimbostratusAPM Policies not enforced after initial login
We are working on implementing per path access restrictions with the BigIP/APM. The restrictions are grouped into the following categories:
1) Public - no login required
2) Restricted - login r...
Yes, this is normal. Today, once the session is established, the access policy is not evaluated for the duration of the session. So, if you started a session for Restricted URIs and then need to enforce security for the Secured ones, you need to do
set an session variable in the VPE indicating whether user performed secured or restricted authentication an iRule that will check the paths for secured - if path is secured, it will check the APM session variable to see how the user authenticated - if they authenticated just for Restricted, kill the APM session and redirect them to the same path they tried to go to(secured) - and the policy execution should kick in and force you to do proper authentication then.

CirrocumulusJohn,
Actually, I have to take it back - I misread the original requirements and for some reason thought you needed step-up authentication here. It sounds like all you want is to allow access to certain URIs based upon LDAP attribute value. You can easily achieve that by doing LDAP query in the VPE and then creating and assigning L7 ACLs to the policy as appropriate. I would suggest an approach of assigning a DENY ACL for the secured URI paths to all the users and then branching out from the LDAP Query and not assigning any ACLs to the users that contain proper LDAP attribute, which means they'll have full access.
