Mapping a directory to an application defines the user-base for an application. Sometimes known as 'application provisioning', directory mappings determine which user stores will be used when authenticating and authorising a user's access request. (Note: users are known in Crowd as principals).
When you defined an application, you chose a default directory for that application to use. Crowd also enables you to map multiple directories to each application. This allows each of your applications to view multiple user directories as a single repository.
To map a directory to an application,
- Login to the Crowd Administration Console.
- Click the 'Applications link in the top navigation bar.
- This will display the Application Browser. Click the 'View' link that corresponds to the application you wish to map.
- This will display the 'View Application' screen. Click the 'Directories' tab.
- This will display a list of directories that are currently mapped to the application. Select the new directory from the drop-down list and click the 'Add' button.
- The new directory will be added to the bottom of the list of mapped directories. You can use the blue up-arrow or down-arrow to move a directory higher or lower in the order:

Why directory order is important
- You now need to choose which users within the directory may authenticate against the application. You have two choices:
- To allow all users within the directory to authenticate against the application, change 'Allow all to Authenticate' to 'True', then click the 'Update' button.
OR:
- To allow only specific groups of users within the directory to authenticate against the application, see 3.4 Specifying which Groups can access an Application.
