<acronym title="LemonLDAP::NG">LL::NG</acronym> can use SAML2 to get user identity and grab some attributes defined in user profile on its Identity Provider (IDP). In this case, <acronym title="LemonLDAP::NG">LL::NG</acronym> acts like an SAML2 Service Provider (SP).

Several IDPs are allowed, in this case the user will choose the IDP he wants. You can preselect IDP with an IDP resolution rule.

For each IDP, you can configure attributes that are collected. Some can be mandatory, so if they are not returned by IDP, the session will not open.
