Emmanuel Lecharny resolved DIRSERVER-658:
-----------------------------------------
Resolution: Fixed
Fixed by modifiying the way NamingContexts are stored in the Attribute object :
they are now stored as String, not as LdapDN objects.
Regression tests passed ok.

> The problem is that when encoding a SearchResultEntry, the values are
> supposed to be Strings or byte arrays, not LdapDNs. When you fetch for DNs in
> the root DSE, the result is stored in the SearchResultEntry as LdapDN
> objects, not Strings, and it's allowad, as the method which set the value
> accept an Object.
> We have to fix two problems :
> - first, check that the Object is either a String or a byte[], nothing else
> (defensive programming)
> - second, avoid storing LdapDN objects where String or byte[] are expected :)
