1. 
2. Click 'Add Application Link'. The 'Link to another server' dialogue will be displayed.
3. Enter the server URL of the application that you want to link to, in the 'Server URL' field. Click the 'Next' button. The 'Link to Reference Application' dialogue will be displayed.
4. Fill out the fields, as follows:
   • Tick the 'Create a link back to this server' checkbox, if you want to create a "two-way" link (i.e. also create a link from the remote server back to your application). If you want to do this, you will need to enter the 'Username' and 'Password'of an administrator for the remote server (if you are not logged into the remote server already):
     Please note, these credentials are only used to authenticate you to the remote server, so that UAL can make the changes required for the new link. The credentials are not saved.
   • 'Accessible URL of this application for the reciprocal link' — This is the URL that is used for features like link rendering. You may have used a server URL that is not accessible to other users in the previous 'Link to another server' dialogue, e.g. an internal IP address. If so, you can change the accessible URL to an address in a domain that is available to other users.
5. Click the 'Next' button. The 'Set Users and Trust' dialogue will be displayed.
6. Fill out the fields to configure authentication for your application link, as follows:
   For more information about configuring authentication, see Configuring Authentication for an Application Link.
   • Select either 'The servers have the same set of users' or 'The servers have different sets of users' depending on how you manage users between the two applications.
   • Tick the 'These servers fully trust each other', if you know that the code in both applications will behave itself at all times and are sure each application will maintain the security of its private key.
7. Click the 'Create' button to create the application link. The 'Configure Application Links' page will be displayed, listing all of the application links that have currently been set up for your application including the one you just added.
