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
authenticate 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.
