occur until you upload a valid license and restart the server. You must always
restart the MCG 3100 after you add or modify the license file.
Manage TLS certificates
A Public Key Infrastructure (PKI) uses Transport Layer Security (TLS)
certificates to provide server authentication and private communication.
With a PKI, the communication between the mobile clients and the
MCG 3100 server is secure.
Perform the following tasks to configure the PKI:
• Enroll with a Certificate Authority (CA).
•
Generate a Certificate Signing Request (CSR).
•
Obtain a signed TLS certificate.
•
Obtain the CA root certificate, intermediate certificate, or both as
required by the CA..
• Install the root or intermediate (or both as required by the CA) and
signed certificates.
• Distribute the CA root certificate.
Enroll with a Certificate Authority
Some CAs, such as VeriSign or Entrust, charge a fee for their services.
Others, such as CACert or RapidSSL, provide free or low-cost solutions.
As an alternative to using a commercial CA, you can build your own. For
example, Microsoft Exchange Server includes tools that enable you to
build a CA server that is exclusive to your organization.
