How to configure SAML SingleSignOn authentication from "SAML SingleSignOn for Jira" app

[Alejandro Carretero Trejo]

Good morning everyone, 

We are trying to migrate the configuration from SAML SingleSignOn external Jira plugin to the embbedd SAML authentication method through Administration -> System -> Authentication Methods

We don't know how to configure properly this authentication and what can we do with the two URLs that we have to send to Identity Provider

Thanks in advance.
