Hoping that someone can point me in the right direction here.
Trying to use Client Certificate Authentication for Exchange Server 2010 ActiveSync. I have got everything setup as per the documentation from Kemp for ESP and EAS. But I appear to have hit an immovable object and seem to be stuck at this error:
The network guys have confirmed that port 636 is open between the Kemp interface and the AD server, but still keep seeing this error appear. If I turn off ESP and use Basic Authentication, LDAPS, then authentication does work OK from the endpoint to the EAS server.
Can anyone point me in the right direction to resolving this?
