External authentication for YCom – SAML, OAuth2, and CAS. Covers config files (data/addons/ycom/saml.php, oauth2.php, cas.php), the ycom_auth_saml/oauth2/cas value fields, default user data, allowed-domain restrictions, and field-mapping via YCOM_AUTH_*_MATCHING extension points. Use when the user integrates SSO, configures OAuth2 providers, maps SAML attributes to YCom user fields, or enables direct-link login.
