Dear all ,
I'm about to move one of our customerrs from exchange to zimbra.
Ive setup atest environment with ZCS 8 and Windows server 2012. After performing all the steps described in the docs of zcs 7 (zcs 8 documentation does not describe spnego configuration) i receive the following error

Failure unspecified at GSS-API level (Mechanism level: Invalid argument (400) – Cannot find key of appropriate type to decrypt AP REP – RC4 with HMAC)

Any help woill be appreciated.

Thanks in advance.
