I thought this feature could be used for enabling the proxy to log access per blackberry PIN - but this does not seem to be possible from the BlueCoat side.
Anyway, I would be interested to know if this helped and how you solved your problem.
Excellent thanks Neo3000, that's the KB I've been looking for to investigate another issue we have.
I will chat with the guys who look after the Proxies and see if we can use this in anyway to address this problem.
Will update this thread when I have the results.
