# CommunityServer Configuration Parameters

For some functionality, the Category component must communicate with the Community component, when you want to cluster user profile data, or when you set user role permissions on your categories. When you use a stand-alone Category component, you must configure the `[CommunityServer]` configuration section to specify the details of the machine that hosts your Community component.

For example:

    [CommunityServer]
    Port=5030
    Host=community.example.com

You must configure this section in the Category configuration file when you install Category as a stand-alone component. It configures communications between Category and Community. For more information about component-based IDOL setups, refer to the IDOL Getting Started Guide.

NOTE: This configuration section is meaningful only in a stand-alone Category component, not in a unified IDOL Server configuration.
