We recently attempted to upgrade our CAS environment from v6.1.X to v6.2.X.
While things looked stable in our TEST environment, we are experiencing an
unexpected, but replicable, issue in our PROD environment.
Two services that we are aware of (PingOne and WebEx) are triggering CAS to
return a 400 Bad Request when initializing a SAML connection against these
services. We have a few hundred other SAML configurations and can see those
requests going through as expected, so this appears to be limited to
certain services. This issue was not persistent in v6.1.7.1 (or, any
previous release in v6.1.X or earlier release that we have used).
We have since rolled back to v6.1.x, but would like to move forward with
our v6.2.x upgrade sooner then later.
Has anyone experienced a similar error?
Below is a dump:
