Hello Michael
Thanks a lot for the solutions.
I have tried possibilities 1 and 2, they all worked out OK. I am going a different way with my project now, i'm gonna use Joget's own directory management and userview as a separate system from Drupal. In a few months i will return to the possibility of integration which is the optimal situation (maybe with Joget 3). For the record, i'm using Drupal 7.1 with Joget 2.0.2.
