Authentication servers (auth servers) are external sources of user accounts, such as an LDAP server, or servers that perform authentication for UserGate, such as RADIUS, TACACS+, Kerberos, or SAML. The system supports the following types of authentication servers:
-
LDAP connector.
-
RADIUS user authentication server.
-
TACACS+ user authentication server.
-
Kerberos authentication server.
-
NTLM authentication server.
-
SAML (SSO) authentication server.
RADIUS, TACACS+, NTLM, and SAML authentication servers can only authenticate users, while a LDAP connector also makes it possible to obtain information on users and their properties.
