We have recently added a new identity management system. A user enters a username and token and is presented with a menu of applications. Some of these applications are protected by TAM (IBM Tivoli Access Manager). When such an application is selected the TAM login page is shown. This means that to access the desired application 2 sets of credentials must be entered!
I am able to determine the user's email address and I would like to pre-fill the user name field on the TAM login page with the email address so that the user only has to enter the password.
Is there any way to set the email address so that TAM can pick it up and offer it as the default user name?
