LDAP (Lightweight Directory Access Protocol) is a TCP/IP protocol used to run queries in the corporate directory. It is used by applications that run a user authentication process.

A read-only user account is used to read and browse through corporate LDAP directories and to validate the credentials of users who want to log in to EV Observe.
