Users and authentication

Adding LDAP servers

 

 

Configuring LDAP support

If you have configured LDAP support and a user is required to authenticate using an LDAP server, the FortiGate unit contacts the LDAP server for authentication. To authentication with the FortiGate unit, the user enters a user name and password. The FortiGate unit sends this user name and password to the LDAP server. If the LDAP server can authenticate the user, the user is successfully authenticated with the FortiGate unit. If the LDAP server cannot authenticate the user, the connection is refused by the FortiGate unit.

The FortiGate unit supports LDAP protocol functionality defined in RFC2251 for looking up and validating user names and passwords. ForitGate LDAP supports all LDAP servers compliant with LDAP v3.

FortiGate LDAP support does not extend to proprietary functionality, such as notification of password expiration, that is available from some LDAP servers. FortiGate LDAP support does not supply information to the user about why authentication failed.

LDAP user authentication is supported for PPTP, L2TP, IPSec VPN and firewall authentication. With PPTP, L2TP, and IPSec VPN, PAP (packet authentication protocol) is supported and CHAP (Challenge-Handshake Authentication Protocol) is not.

The common name identifier for most LDAP servers is cn. However some servers use other common name identifiers such as uid.
