Recently, my IDP had to turn on SAML Assertion Encryption. After doing this, I get an error upon logging into UIM with SAML.
The error is: Unable to Process SAML Request.
When my IDP turns assertion encryption off, everything works properly, and SAML login occurs as expected.
Release : 9.2.0
Component : UIM - UMP
SAML Encryption Assertion is not supported in UMP 20.1 or below. Disable Encryption Assertion in SAML to allow SAML authentication.
Development has reported that UMP 20.1 has the same version of Liferay as in 9.20. In 20.3, no Liferay will be used. They don't anticipate any of the problems existing in 20.3 that will be released in Q3 2020.
