On March 3 we had to update the SSO IDP Metadata as a result of our SSO team needing to refresh their certificate. After updating the IDP Metadata, we started having random issues with folks being able to log into our Mendix application via SSO. The first time it would fail and they’d need to refresh by clicking the “Try again” button which would then let them log in. Finally, we decided to redeploy the Mendix application and since doing that, we are no longer seeing the same SSO errors. Does anyone understand why a reboot was required after updating the SSO IDP Metadata? NOTE: We are presently using Mendix Studio 7.23.19 and are in the process of upgrading to 8.18.15.
