PHP SAML Toolkit version has changed in SuiteCRM-7.8.2 which rendered existing SAML configurations broken. I also had the old version patched for SLO support. The patch proved difficult to port due to significant changes in the code and it didn’t make much sense either as the new toolkit version should have supported SLO out of the box.

Below are my short notes on how to migrate relevant SimpleSAMLphp IdP configuration to newer PHP SAML Toolkit version. Also included is SLO patch for SuiteCRM-7.8.18 LTS.
