When Auth-Type is set to SQL, the database is assumed to contain usual
MD5 hashed passwords. These are not to be confused with MD5
hashes. The hashed password is:

        '$1$' + SALT + '$' + MD5HASH


where strings enclosed in a pair of quotes appear as they are,
+ denotes concatenation, SALT is the salt value used when generating
hash and MD5HASH is the hash value itself.

If your system is able to keep MD5 encoded passwords in its
passwd/shadow database, you will see the same format used there.
