Stéphane,
Currently an INegotiator is needed to transport the userID (possibly
together with other credentials information) to the server. If there is
none for a connector, then the userID is ignored.
We should address this issue by either:
1) Throw an exception if a userID is set locally, but no negotiator
2) Make the connector transport the userID himself if no negotiator is
configured. Maybe we should also remember some flag that these userIDs
are somewhat "weaker" than those of negotiated credentials...
Please feel free to file a Bugzilla for your preference.
Cheers
/Eike

Hi Eike,
In the meantime, I've found the INegociator API but I'm facing a NPE
problem in using it (see post
http://www.eclipse.org/newsportal/article.php?id=41212&g roup=eclipse.tools.emf#41212).
Option 1) suits the need.
I've filed a bugzilla https://bugs.eclipse.org/bugs/show_bug.cgi?id=273568
Stephane.
