Two factor LDAP authentication systems and methods are presented. In one embodiment, implementation of a method for authenticating a user through a two factor process includes: at an LDAP proxy server, receiving a BIND request from a client, wherein the BIND request is for authenticating a user associated with a username to an LDAP server, and wherein the BIND request comprises a password comprising a first factor security code and a second factor security code; stripping the second factor security code from the password; reconfiguring the BIND request with the password that is stripped of the second factor security code; forwarding the reconfigured BIND request to the LDAP server for authentication of the username using the first factor security code; performing authentication of the second factor security code; and positively authenticating the username to the LDAP server when the first factor security code and the second factor security code are authenticated in connection with the username.
