Probably the easiest way is to handle "registering" the user with jForum yourself instead of using the SSOUtils.register method. This way you can map any LDAP information you want into jForum User fields. E.g., sn to lastName, etc.
Once you've done that, you can change the templates to use whatever property you want to display instead of the user id. [originally posted on jforum.net by monroe]
