LDAP (Lightweight Directory Access Protocol) is a protocol that allows accessing and maintaining distributed directory information services over a network. User Directory integration is a feature of Identity Awareness that allows Check Point products to use LDAP servers as identity sources. When configuring LDAP with User Directory integration, changes applied to a User Directory template are reflected immediately for all users who are using that template. A User Directory template defines the settings for connecting to an LDAP server and retrieving user information3.
