In a deployment with Sun Java System Access Manager, you can assign Instant Messaging and presence services to end users with the imadmin assign_services command. Alternatively, you can use the Access Manager console.
In iim.conf, ensure that the iim.policy.modules parameter has a value of identity.
See iim.conf File Syntax for information on iim.conf.
From the command line, run imadmin with the assign_services option:
imadmin checks the value of the iim.policy.modules parameter in iim.conf.
Enter the Base DN of the organization under which user entries are stored.
This is the organization that contains the user entries managed by Access Manager.
Next, imadmin assigns Instant Messaging and presence services to the users in the organization you specify.
