Spring Security with LDAP with MD5 password

[JohnTheDroider]

I am working on a project using Spring and Spring Security with LDAP. I had my project working great with LDAP before we MD5 the user passwords. Now that we MD5 the users passwords I am trying to find a way in the Spring XML to tell Springs to MD5 the password before checking LDAP.

Below is my XML

I suggest a read of the spring security reference guide as it is explained in there. Spring Security is checking the passwords NOT your ldap provider.
