Symptoms

The BIG-IP system expects to receive SLO responses on a particular URL: (.../post/slr). TMM may restart when SLO response is received on an SLO request URL (.../post/sls).

Impact

TMM reboots and is temporarily unavailable.

Conditions

The BIG-IP system is configured as SAML SP or IdP. SLO response is received on SLO request URL.

Workaround

There are two workarounds: 1. Reconfigure another SAML party to send SLO messages to a proper URL. 2. Disable SLO

Fix Information

Proper validation was added to check correct messages were received on proper URL. Logging was added for failing cases.
