Hi Jaikiran,
I kind of worked around 1 but with a serious kludge which involved caching various InitialContexts based on credentials. Your method is most definitley more elegant. Thank you for putting the time in this. One thought that kept coming back is with the whole notion of "fixing" the credentials at connection establishment time and effectively do away with credential propogation at call time. I do see why to a certain extent and reworked our code to work with this model. You guys truly do a fantastic job. Please keep it up.
