Issue/Introduction

Users cannot logon anymore to Automic using SAML in case the IDP provides a Based64 Encoded signature with additional breaks (CRLF).

This was working fine on version 21.x and stopped working after upgrading to 24.4.0 HF2.

The error in the JWP log is the following:

20250513/123234.042 - 39 U00045325 Received SAML token as '<samlp:Response>'
