Issue

A discrepancy in URL parameter handling has been identified when special characters (such as ÄÖÜ) are used in application URLs. The behavior has been observed to vary based on authentication status. When users are already authenticated via SSO, the special characters are displayed correctly. However, when authentication has not yet occurred, and the SSO process needs to be completed first, the special characters in the URL parameters become incorrectly encoded/decoded, resulting in a malformed character display.

Environment

SAML all versions

Cause

This is the expected behavior from the SAML module when it decodes URLs

Solution / Workaround

This behavior can be changed by enabling the SAML constant DisableDecoding_Deeplink_URL.
