Configure EJBCA Server

The following sections cover how to configure the EJBCA server.

Launch an EJBCA Enterprise Cloud Server from AWS

For instructions on how to deploy EJBCA Cloud from Amazon Web Services (AWS) and log in to the EJBCA Admin Web for the first time, refer to the EJBCA Cloud AWS Launch Guide.

Certificate Authority Set up

If you do not already have Certificate Authorities (CAs) configured in EJBCA, follow the EJBCA Enterprise Quick Start Guide to set up a 2 Tier CA Hierarchy.

Modify Workstation End Entity Profile

The Intune device certificates use an Organizational Unit in the Subject DN Attributes. Since this attribute was not added following the Create End Entity Profiles instructions in the EJBCA Cloud AWS Quick Start Guide, do the following to add the attribute in the Corporate Workspace End Entity Profile:

  1. Under RA Functions, select End Entity Profiles.

  2. Edit the Corporate Workspace EE Profile and under Subject DN Attributes, select the (OU) Organizational Unit field for subject DN, and click Add.

  4. The new SCEP alias is added to the list of aliases. Next, proceed to configure the Intune SCEP Alias.

Configure Intune SCEP Alias

To configure the newly created Intune SCEP alias:

  1. Click the intune SCEP alias.

    • Operational mode: Select RA.

    • RA End Entity Profile: Select.

    • RA Certificate Profile: Select the Certificate Profile configured in the End Entity Profile.

    • RA CA Name: Select the Issuing CA configured in the End Entity Profile.

    • Application ID from Azure: Enter the ID obtained from following the procedure in Configure Intune.

      The settings RA name generation scheme, RA name generation parameters, RA name generation prefix, and RA name generation postfix are left with the default values as depicted in the screenshot.

      A Proxy was not required for EJBCA to connect to Intune. If a proxy is required then specify the applicable fields.

  4. Click Save to store the Intune SCEP alias configuration.
