What is a metadata XML file in SSO, and what information does it include?

Created by Amit Kadam, Modified on Wed, 27 Aug at 12:46 PM by Amit Kadam

  • The metadata XML file is a configuration file used in SAML-based Single Sign-On (SSO) to establish trust between the Identity Provider (IdP) and the Service Provider (SP).

  • It typically contains:

  • IDP name/ID – A unique ID that identifies the IdP or SP.

  • SSO URLs – Endpoints for user authentication and logout.

  • Certificates/Signatures – Used to sign and/or encrypt SAML assertions.

  • NameID Formats – Format of the user identifier (e.g., email, persistent ID).

  • Bindings – Communication methods like HTTP-Redirect or HTTP-POST.

  • Optional Info – Contact details and organization metadata.
