Bug Description: When using the password modify extended operation,
if a new password is not supplied, the server should generate a new
random password and return it to the user in en extended response.

Fix Description: If a user doesn't supply a new password in the password
modify extop request, we will generate a random 8 character password,
store it as the users password, and return it to the user in the
modify extop response.
I also removed a block of code that was setting the extop return OID
pb to the password modify OID. RFC3062 explicitly states that the
modify response should have the responseName field absent.
