In my example A and B were permissions. Let me clarify: You have a CWT authorizing to "read" (that's my A) traffic in group Z, now you also want authorization to "write" messages to group Z (that's my B). What I'm saying is you should get a new CWT that says "read+write on Z" (and not a separate one that says "write on Z" to combine with the first one "read on Z"). /Ludwig -- Ludwig Seitz, PhD Security Lab, RISE Phone +46(0)70-349 92 51
