We have a custom process that is authenticating with an admin user, we tested it in a non prod env. and it worked, but not in Prod.
We recently made a SSO and Upgrade.
Release : 15.9.1
Component : CA PPM SAAS BUSINESS PROCESS MANAGEMENT
When customer switched to SSO their user name needed to be in the form of email ids but GEL script was attempting to login using old user id which was not an email format.
