Re: Add ldapservice connection parameter

Updated patch to only append an error message when rc from
ldapServiceLookup is 2. This is the only non zero return of
ldapServiceLookup that does not append an error message because it is
meant to signal that the lookup was not successful but we can continue
parsing the service file. In this case I think it makes sense to raise
an error and append an error message. Also increased the specificity
of the test assertions.

I added this because now that there is a connection parameter that
begins with ldap it could cause a confusing error message if the user
tries to use ldapserviceurl in a service file and are then given an
error message that roughly says 'invalid LDAP URL ".*" scheme must be
ldap://'.
