When you are connecting to an application that is not part of a federation, you may need to supply that application with your metadata address. Metadata is available for both SAML 2 and the older SAML 1.1 standards. Where there is a choice, SAML 2 is the one to select. If the application is unclear, try SAML 2 first.

You will need to know your OpenAthens domain name. This is usually the same as the scope registered against your domain organisation as seen on the organisation summary.

Metadata address:

SAML 2 https://login.openathens.net/saml/2/metadata-idp/DOMAIN
SAML 1.1 https://login.openathens.net/saml/1/metadata-idp/DOMAIN

E.g. if your OpenAthens domain is institution.ac.uk, your SAML 2 metadata address will be:

https://login.openathens.net/saml/2/metadata-idp/institution.ac.uk

If you want to view this in your browser you may need to add a ?browser parameter to the end of the link, e.g.  https://login.openathens.net/saml/2/metadata-idp/institution.ac.uk?browser

Manually specifying connection settings

The metadata address should be sufficient for most SAML targets, however some may instead want you to specify endpoints, certificates and other data manually instead. If they do:

Endpoints / SSO address:
SAML 2https://login.openathens.net/saml/2/sso/DOMAIN
SAML 1.1https://login.openathens.net/saml/1/sso/DOMAIN
Certificate

This will be the x509 certificate in the metadata, topped and tailed as follows. This is sometimes called PEM format.
