Polycom®, Inc. 965
● Support of Extended Key Usage (EKU) for both:
Client Authentication
Server Authentication
The certificate template used by your CA server may need modification to meet the Collaboration Server
requirements.
Certificate Requirements
Secure Mode
In Secure Mode, the certificate requirements depend on the Skip certificate validation for user logging
session field.
Ultra Secure Mode
In Ultra Secure Mode, each Polycom device must have security certificates for the entire Chain Of Trust.
The Collaboration Server must have:
● The public certificate of each server in the CA Chain or hierarchy that issued its certificate.
For example: RootCA > IntermediateCA > SubCA
● The public certificates of the chain that issued the administrator’s identity certificate.
For example: UserRootCA > UserIntermediateCA > UserSubCA
For more information see Ultra Secure Mode chapter, Certificate Validation and Certificate Revocation.
Configure Certificate Management
Within a PKI environment, certificate revocation policies are used to ensure that certificates are valid.
Certificates can expire or be revoked for various reasons (RFC 5280).
The Collaboration Server enforces these certificate revocation policies through Certificate Revocation Lists
(CRLs). CRLs are required for each CA Chain in use by the Collaboration Server. These CRL files must be
kept current. For more information see the Ultra Secure Mode chapter, Certificate Configuration and
Management and (PKI) Public Key Infrastructure.
Switching to Secure Mode
The following operations are required to switch the Collaboration Server to Secure Mode:
● Purchase and Install the SSL/TLS certificate
● Modify the Management Network settings
● Create/Modify the relevant System Flags
Purchasing and Installing a Certificate
Once a certificate is purchased and received it is stored in the Collaboration Server and used for all
subsequent secured connections. For more information see the Ultra Secure Mode chapter, Adding
Certificates to the Certificate Repository.
