Mashup: Post upgrade to 7.2.1 user sees PRPC Login Screen
User is upgrading application from PRPC 6.2 version to Pega 7.2.1.
The existing portal code uses PRGateway but user is tying to use the new Mashup code and eliminate the PRGateway.
When running the gadget users are getting the Pega login screen.
Steps to Reproduce
After upgrading the Data-Admin-AuthService needed to be reset to use External Authentication because the client is using WebSeal for SSO.
After an upgrade the Data-Admin-AuthService IACAuthentication gets updated as part of the upgrade process and resets the authentication type to "Use Credentials Stored in PegaRULES" :
Note: This change requires a system restart.
Important Note on PRPC Password:
When using Mashups one should never configure the application to send PRPC a base64 encoded password in a production environment.
This "Use Credentials Stored in PegaRULES" is initially set this way for testing and also for gadget creation with the usage of PRGateway.
Since PRGateway is not longer supported starting in Pega 7.2.1 check whether the default vaule set to "Use externally stored credentials".
