Single Sign On (SSO) to bookshelf is failing in some scenarios
Incident Report for VitalSource
Postmortem

The root cause of this incident was related to the way we handle SSL certificates in our API redirect layer, which in turn caused a narrow set of SSOs into our Bookshelf product to fail.  This issue was exposed when our proxy networking layer did a routine cycle of a certificate. We have corrected this issue and audited our systems for any other scenarios where this might occur.
