Made sure integration tests for article sample automatically start in-process LDAP server.

DirContextAdapter#setDn() now throws IllegalStateException if setDn is called on an 
instance in update mode (this was previously silently ignored)
Fixed problem in LdapTreeBuilder caused by the new behaviour of DN in DirContextAdapter
(i.e. that the actual DN instance of the DirContextAdapter is no longer returned by 
getDn()).
