Symptoms

Per-req policy authentication fails when an empty password is detected. Following errors are seen in apm logs: -- err apmd[13930]: 01490301:3: /Common/test_sp::abcdef78/Common/test_auth/XXXXXXX==: Empty session variable value received from tmm. -- err apmd[13930]: 01490302:3: /Common/test_sp::abcdef78/Common/test_auth/XXXXXXX==: Failed to decrypt session variable 'subsession.logon.last.password' from tmm with error code: 3.

Impact

APM end users cannot change a password/token or access backend resources.

Conditions

-- APM is licensed and provisioned. -- Per-req policy is created with at least one Auth agent.

Workaround

None.

Fix Information

Per-request policy auth no longer complains about empty password. If the backend server accepts an empty password, auth should work fine.
