Overview#Simple Authentication (in LDAP) is an LDAP Authentication Method using a DN and Password in a Bind Request for LDAP Authentication to a DSA.
In LDAP the LDAP Client performing a Bind Request to an LDAP Server using a DN and Password. When this type of Bind Request is performed, it is often called a "simple bind". The client uses the provided DN to identify itself to the server, and the password is used to verify that the client is who it claims to be.
Note that simple authentication does not protect the password in any way, and therefore it is generally recommended that it only be used over a secure communication channel like that provided by SSL or StartTLS.
