6.3. Authentication servers

Authentication servers are the external sources of user accounts for UserGate, e.g. LDAP servers, Radius, TACACS+, Kerberos or SAML. UserGate supports:

  • LDAP-connector

  • Radius authentication server

  • TACACS+ authentication server

  • Kerberos authentication server

  • NTLM authentication server

  • SAML (SSO) authentication server

The Radius, TACACS+, NTLM, SAML and Kerberos authentication servers can only authorize users, while the LDAP-connector can provide information about users and their properties.
