> The documentation talks about LDAP support with mapping user names to derby users using
the derby.user.'userName' property. 
> See links

> http://db.apache.org/derby/docs/dev/tuning/rtunproper27355.html
> Per the documentation, one can use the derby.user property to set the DN for a user,and
when using LDAP, setting the search filter to derby.user will pick up the DN from this property
if available. This is not working when I tried it out by caching a user's dn as a database-level
property.
> Found the following issues:
> 1)Setting the database property derby.user.userName to a DN does not work:
> Problem in AuthenticationServiceBase#map. 
> -- If there is a system property derby.authentication.provider=LDAP, setting of derby.user.userName
to a DN value as a database property will encrypt the DN value and store it. The code seems
to expect that the derby.authentication.provider is set to LDAP as a database property, else
it considers it as a password and encrypts the value. 
> -- it doesnt return the correct mapped value for the property for the LDAP and derby.user.userName
case. Returns null instead of returning the clear text DN value.
> 2) the LDAP code itself doesnt pick up the userDN.
> In LDAPAuthenticationSchemeImpl#authenticateUser
>             if (useUserPropertyAsDN)
>                 userDN =
>                     authenticationService.getProperty(
>                         org.apache.derby.iapi.reference.Property.USER_PROPERTY_PREFIX)
> Here  USER_PROPERTY_PREFIX is derby.user.
> The key should be USER_PROPERTY_PREFIX+userName.  
> 3) After the code issues are fixed, it would be nice if documentation can be added to
give a full example of how to go about doing LDAP authentication with caching DNs in derby.user.
