I'm trying to get the Content Editor Web Part (CEWP) religion by
experimenting with the Users and Groups Web Service. In particular,
I've been playing with the GetRoleCollectionFromUser method to return
a given users' security roles. This works fine when I pass in a
username but I am trying to do this for the current user. I'm
struggling to determine a full proof, cross browser, default security
settings solution to the problem. Everything I have read so far
suggests that this is impossible thru the browser's mechanisms. I am
wondering if there was some SharePoint specific way of accomplishing
this that I am missing. In particular I have tried passing in null
and the empty string to the web service method and they yield the
predicatable SOAP Fault.
