SSO Portal Authentication stopped working again in dev and never worked on production

Products

• CA API Developer Portal
• CA API Gateway

Issue/Introduction

After updating certificates and switching from the deprecated SSO SAML authentication to new SAML authentication, authentication is failing. It was working a week ago in Dev and never worked in Production.

Environment

On-Prem gateway 9.3
SaaS Portal 4.2.10
 

Cause

The Service Provider ID did not match exactly with what was configured as the service provider from ADFS.


 

Resolution

When configuring SAML Authentication click  “Provider Configuration”

Service Provider ID

https://servername.example.com

“Specify the service provider identification that identifies the CA API Portal service”

 

The Value MUST must be identical to the service provider defined - this needs to include trailing slashes if they exist

 

Pre-prod https://servername.dev.example.com = worked

Prod https://servername.prod.example.com = failed with exception on portal with Null attributes

 

Production trailing slash was defined to fix changed

https://servername.prod.example.com

To

https://servername.prod.example.com/
