Documentation for Crowd 1.6. Documentation for other versions of Crowd is available too.
To ensure that your Crowd server can only be used by legitimate applications, Crowd will only allow applications to log in from known addresses. This means that you need to specify the IP address(es) and/or hostname(s) of each application.
When you add a new application, you will specify the application's IP address. After adding the application, you can update the IP address if necessary, as described below. In some cases, you may need to add the applicable host name as well as the IP address.
IP address and/or host name?
You should always specify the application's IP address. Some application servers may pass the host name to Crowd, instead of the IP address. If this happens, Crowd will not grant the application's authorisation request unless Crowd recognises the host name. For such cases, you should specify the host name as well as the IP address.

Common Misconfiguration
