Guillaume Nodet commented on KARAF-3114:
----------------------------------------
Weird, i tried that and it succeeded.
Fwiw, I fixed a bug with the admin role recently, so that may have impacted (in
the right way) the behavior : if the user does not have the admin role, the
call will fail, and that was the case before I fixed
