Chapter 8. Defining Functions for Authentication
This chapter explains how to write a plug-in function to bypass or replace the standard function for authentication with your own function.
8.1. Understanding Authentication Methods
Authentication methods for LDAP is described in RFC 4513, available at http://www.ietf.org/rfc/rfc4513.txt.
Two methods that you can use to authenticate clients are simple authentication and SASL authentication:
- Simple authentication is described in RFC 4513, available at http://www.ietf.org/rfc/rfc4513.txt.Simple authentication provides minimal facilities for authentication. In the simple authentication method, clients send a DN and password to the server for authentication. The server compares the password sent by the client against the password stored in the client's directory entry.
- Simple Authentication and Security Layer (SASL) is described in RFC 4422, which you can find at http://www.ietf.org/rfc/rfc4422.txt.SASL provides the means to use mechanisms other than simple authentication and TLS to authenticate to the Directory Server.
