CRAM-MD5 SASL Mechanism Handler

The CRAM-MD5 SASL mechanism provides the ability for clients to perform password-based authentication in a manner that does not expose their password in the clear.

Rather than including the password in the bind request, the CRAM-MD5 mechanism uses a two-step process in which the client needs only to prove that it knows the password. The server sends randomly-generated data to the client that is to be used in the process, which makes it resistant to replay attacks. The one-way message digest algorithm ensures that the original clear-text password is not exposed. Note that the algorithm used by the CRAM-MD5 mechanism requires that both the client and the server have access to the clear-text password (or potentially a value that is derived from the clear-text password). In order to authenticate to the server using CRAM-MD5, the password for a user's account must be encoded using a reversible password storage scheme that allows the server to have access to the clear-text value.
