Cyrus IMAP HOWTO

4. Different SASL Authentication Methods

4.1 sasldb

This is the default method of authentication. It stores usernames and passwords in the SASL secrets file sasldb. In this HOWTO, I assume you are using the sasldb method of authentication.

4.2 LDAP

The following definition came from the OpenLDAP website. Lightweight Directory Access Protocol (LDAP) is an open-standard protocol for accessing information services. The protocol runs over Internet transport protocols, such as TCP, and can be used to access stand-alone directory servers or X.500 directories. This method isn't discussed in this HOWTO, but here is a link to a page with patches and info:
