If you configure secure communication between the BlackBerry® MDS Connection Service and web services, you must also configure the BlackBerry MDS Integration Service to permit BlackBerry® MDS Runtime Applications to establish HTTPS connections to external web services.

If external web services are deployed over HTTPS for secure communication, you must configure the BlackBerry MDS Integration Service to establish HTTPS connections to web services.

2. Click the instance that you want to change.
3. Click Edit instance.
4. In the General section, in the Allow Web Services Access over SSL drop-down list, click True.

A developer in your organization can sign a BlackBerry® MDS Runtime Application with a digital certificate. You can add the digital certificate to a BlackBerry MDS Integration Service to define the BlackBerry MDS Runtime Application as a trusted application with a valid application bundle signature. You can only install BlackBerry MDS Runtime Applications with a valid application bundle signature on BlackBerry devices.

1. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > MDS Integration Service.
2. Click the instance that you want to change.
3. In the Certificates list, click Add new certificates.
4. In the Alias name field, type a name for the certificate.
5. Click Browse. Navigate to the certificate that you want to add.
6. Click Add certificate.

By default, users can only install BlackBerry® MDS Runtime Applications that a developer signed with a digital certificate. However, you can permit users to install unsigned BlackBerry MDS Runtime Applications on BlackBerry devices.

1. In the BlackBerry Administration Service, on the Servers and components menu, expand BlackBerry Solution topology > BlackBerry Domain > Component view > MDS Integration Service.
2. Click the instance that you want to change.
3. Click Edit instance.
4. In the General section, in the Allow unsigned applications drop-down list, click True.
5. Click Save all.
