I want to use our Active Directory (Windows 2008 R2) with iFolder. But there is a problem with the certificates,

because we're using our own CA, with a Intermediate CA. So, the setup accepts the Intermediate CA certificate

from the server, but then brakes with (Root CA -> Intermediate CA -> Certificate):

LdapException: (91) Connect Error System.IO.IOException: The authentication or decryption has failed. ---> Mono.Security.Protocol.Tls.TlsException: Invalid certificate received from server.
I imported the CA and Intermediate CA in the various mono certificates stores, but nothing helps. Can someone

help me or give me a hint where to fix the problem?

Big thx
