PC-Duo overview

authenticate itself to the server. PC-Duo implements two types of authentication to

support this:

 "Identity Authentication"

 "Endpoint Authentication"

Identity Authentication

In general, this operation answers the following security question: How does the server

know who the client is? A PC-Duo application acting as a server will not provide access

or information to any PC-Duo application acting as a client until it can validate that client's

identity. PC-Duo provides the server three different methods of authenticating the identity

of the PC-Duo client:

Connection

Windows

authentication

Simple

password

Shared-

secret

password

Peer-to-peer

Yes

Gateway-managed (Gateway & Host are in same domain)

 Master-Gateway

relationship

Yes

 Gateway-Host relationship

Yes

Gateway-managed (Gateway & Host are not in same domain)

 Master-Gateway

relationship

Yes

 Gateway-Host relationship

Yes

 Windows authentication: By default, a PC-Duo application acting as a server uses

Windows authentication to check the Windows credentials of the client application:

 The Host will check the Windows credentials of the PC-Duo Master user in

the case of a peer-to-peer connection;

 The Gateway will check the Windows credentials of the PC-Duo Master users

in the Master-Gateway part of a Gateway-managed connection;

 The Host will check the Windows credentials of the user logged into the

Gateway in the Gateway-Host part of a Gateway-managed connection (when

Host and Gateway are in the same domain).

NOTE: If Host and Gateway are not in the same domain, Windows authentication will not

usually be available. In that case, Host and Gateway will rely on Shared secret password.
