SAP Litmos can be configured as a SAML SSO yapplication in yapster

Setup generally follows the regular SAML SSO procedure https://guide.yapster.dog/en/articles/4612357-sso-setup , although you will need to ask Yapster for the SAML metadata to paste into the SAP Litmos configuration form

The Service Provider metadata is available from the "Click here for SP metadata" link in the SAP Litmos configuration form, and will provide the SP details Yapster needs to configure the link

Additionally, you must uncheck the "Verify assertion signatures and encryption" checkbox in the SAP Litmos configuration form - with this checked, SAP Litmos will expect encrypted attributes, but Yapster does not provide encrypted attributes, so leaving this checked will cause the SSO to fail
