Troubleshooting: SAML SP-Initiated Realm Shows "Error on MultiDomainRelayState"

Version Affected: All
 
 

Overview

When configuring a SAML SP-initiated realm, after entering a username and password, the user receives the following error:

Error on MultiDomainRelayState: Object reference not set to an instance of an object.

 

Cause

The service provider (SP) is not providing an Assertion Consumer Service (ACS) URL, so the Identity Provider (IdP) POSTs back to itself in a loop.

 

Resolution:

To resolve this, set the SAML Consumer URL on the Post Authentication tab of the SAML realm being configured, as shown below.
