Issue/Introduction

Configured SiteMinder SSO per tech note specifications. IDP flow works, but SP flow gives a 500 error and fails to redirect.

Error Text

500
Sorry, something went wrong.
But rest assured this is not a security breach.
Please hit Reload on your browser, or try visiting the page again later. 

Cause

The SiteMinder metadata contains malformed timestamps in the 'validUntil' attribute. 

Resolution

Manually edit the timestamps to follow the following format:
"%Y-%m-%dT%H:%M:%SZ"
ie: 2021-05-01T04:02:41.274Z

In some cases, SiteMinder returns a 400 error after this solution. See CASB CloudSoc SiteMinder SSO getting 400 error  or navigate to step 8. in Configuring a SiteMinder partnership and change AuthBinding to HTTP-Post
