      1. Issuer/ Entity ID.
      2. SAML Login URL.
      3. SAML Logout URL (only if you want users to logout from IDP when they logout from atlassian application. eg.Jira).

      6. SAML Login binding type (optional).
      7. SAML Logout binding type (optional).

      • Go to Service Provider Info and give the link shown below to your Identity Provider. When you click on the link, you will be able to view the metadata for the SAML Single Sign On app.

              ACS URL This is the URL the IdP will return SAML authentication requests to.

              Audience URI IdP will prepare SAML authentication requests for.
              Recipient URL IdP will return SAML authentication requests to.
              Destination URL IdP will return SAML authentication requests to.
              Certificate This Certificate is used validate SAML request and used to decrypt encrypted SAML assertions from the IDP.
