3155479 - Invalid request, ACS Url in request doesn't match configured ACS Url

Symptom

Identity Authentication is used as a proxy. The authentication is failing and ending with message on the Identity Authentication UI: Sorry, but you are currently not authorized for access.

Investigating the SAML trace, the below StatusMessage can be seen:

  • <saml2p:StatusMessage>Invalid request, ACS Url in request https://<tenant_ID>.accounts.ondemand.com/saml2/idp/acs/<tenant_ID>.accounts.ondemand.com doesn't match configured ACS Url https://<tenant_ID>.accounts.ondemand.com/saml2/idp/acs/<tenant_ID>.accounts.ondemand.com?sp=<sp_name>&index=<index_number>.</saml2p:StatusMessage>

In the Identity Authentication Troubleshooting log the below similar error is printed:

  • message=ASJ.saml20_sp.000025# Service Provider has received SAML2Response from Identity Provider [<corporate_IdP_EntityID] that contains an error status code [urn:oasis:names:tc:SAML:2.0:status:Requester].
