Configuring a BlackBerry MDS Connection Service to trust web servers
You can configure the BlackBerry MDS Connection Service to permit BlackBerry devices to pull application data and updates from trusted or untrusted web servers. If you want to open trusted connections between web servers and the BlackBerry MDS Connection Service, you must import the certificate for the web server into the JRE certificates keystore file (JRE cacerts).
The BlackBerry MDS Connection Service supports LDAP, OCSP, and CRL to retrieve certificates and certificate status, and HTTPS and SSL/TLS for connections that use trusted certificates.
