SimpleAuthenticator ehancements, inclduing support for one-way hash for admin password in server.xml
----------------------------------------------------------------------------------------------------

                 Key: DIRSERVER-817
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-817
             Project: Directory ApacheDS
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.0, 1.5.0
         Environment: N/A
            Reporter: Norval Hope


Currently persistent storage of passwords as one-way hashes is supported for partitions, but
the admin password appears as cleartext in server.xml. I am submitting a patch that allows
a one-way hash to be used in server.xml to protect the admin passord. Unfortunately if a user
wants both of these features at the same time:
    a) one-way hashes used for password persistently stored in AD partition    AND
    b) one-way hash used for admin password in server.xml
then SimpleAuthenticator has to accept one-way hashes for both "userPassword" (persistently
stored value) and "creds" (password provided in bind, which takes text from server.xml in
 the case where front-end of server authenticates to back-end in org.apache.directory.server.core.jndi.ServerContext)
and compare them literally when both are one-way hashed. This effectively results in the password
being in cleartext (or more exactly a cleartext alias) in server.xml again, but in a form
that might put off potential hackers (a very big "might"). Hence end-users really end up choosing
between option a) OR b) above.

Also included in the patch is support I needed to get an inflexible legacy client to talk
to AD. As AD doesn't support changing the DN of the admin users, and the client didn't support
changing of the bind DN it used, I added a simple "java.naming.security.principal.alias" property
which allowed specification of an alias for AD's admin user's DN.

Not sure how much interest any of this to anyone else, but thought I'd raise a JIRA about
the cleartext password in server.xml and may the patch available in case. The root problem
seems to be the fairly strange way the the AD front-end needs the admin password from server.xml
to bind to the back-end.
