When the BIG-IP system is configured as SAML SP, there are two bindings supported for SLO profile: HTTP-Redirect and HTTP-POST (default option). If the BIG-IP system is configured to initiate SAML SP SLO profile with redirect binding - tmm may restart.


Tmm restarts. Traffic disrupted while tmm restarts.


-- Configure the BIG-IP system as SAML SP. -- Configure HTTP-Redirect binding for SLO profile. -- Initiate SLO on SAML SP.


Reconfigure the BIG-IP system to use HTTP-POST binding for SLO profile. Configuration should be changed on IDP connector objects.

Fix Information

Tmm no longer restarts when SAML SLO is initiated by SP using redirect binding.
