I have created a SOAP service which has username and password in SOAP headers. I want to authenticate username and password Against Internal Identity Provider. For Rest
Is there OOTB option available.
You can use the 'Require XPath Credentials' assertion along with the 'Authenticate Against Internal Identity Provider' assertion.
Require XPath Credentials Assertion - CA API Gateway - 9.3 - CA Technologies Documentation
A sample has been attached. Let me know if this helps.
