[keycloak-user] ADFS SAML Logout

[Adam Keily]

Hi,

Can anyone shed any light on this. I have created a SAML IdP in keycloak for our ADFS server. Signin works fine, but when I try to logout, I get an internal server error 500.

In the log I just see the below error. If I remove the value for Single Logout Service URL I am signed out of Keycloak but not ADFS. It seems if I have any value in that field, I get the exception below. Even if I put in a dummy https://test.com it breaks.

I've tried recreating the IdP config. Tried different realms and keycloak instances. I'm currently testing using the Red Hat SSO 7.1. version.

Help appreciated.
Thanks
Adam
