When the Polycom RealPresence DMA system connects to a Microsoft Active Directory server, it 
may present a certificate to the server to identify itself. 
If Active Directory is configured to require a client certificate (this is not the default), the Polycom 
RealPresence DMA system offers the same SSL server certificate that it offers to browsers 
connecting to the system management interface. Active Directory must be configured to trust the 
certificate authority, or it rejects the certificate and the connection fails. 
When the Polycom RealPresence DMA system connects to a Microsoft Exchange server (if the 
calendaring service is enabled; see 
), it may present a certificate 
to the server to identify itself. 
Unless the Allow unencrypted calendar notifications from Exchange server security option is 
enabled (see 
), the Polycom RealPresence DMA system offers the same SSL server 
certificate that it offers to browsers connecting to the system management interface. The Microsoft 
Exchange server must be configured to trust the certificate authority. Otherwise, the Microsoft 
Exchange Server integration status (see 
) remains Subscription pending indefinitely, the 
Polycom RealPresence DMA system does not receive calendar notifications, and incoming meeting 
request messages are only processed approximately every 4 minutes. 
When the Polycom RealPresence DMA system connects to a RealPresence Collaboration Server or 
RMX MCU configured for secure communications (this is not the default), a certificate may be used 
to identify the MCU (server) to the Polycom RealPresence DMA system (client). 
When performing call signaling requiring TLS, the Polycom RealPresence DMA system presents its 
certificate to the connecting client (one-way TLS). If the Require mutual authentication 
(validation of client certificates) SIP Settings option is enabled (see 
), the 
system uses the installed CA certificates to authenticate the connecting client’s certificate as well 
(mutual TLS).
