Logout Failing - No active session(s) found matching LogoutRequest

[Lipscomb, Gary]

Hi list,

I’ve got an issue with logging out from an SP Replicon.

The IdP (v4.1.4) is reporting [1] "No active session(s) found matching LogoutRequest".

The LogoutRequest [2] from the SP

Am I correct in assuming that this is failing since the NameID element in the logout request doesn't contain the Format type as a minimum?
Does it also require the SessionIndex obtained from Authn Response?

Regards
Gary
