We have added a new environment variable (accessible from bezl.env.user) which has all of the information about the user in one place (versus using bezl.env.currentUser and bezl.env.currentUserName).
Available fields currently are:
bezl.env.user.id = the login name for the current user
bezl.env.user.name = the name for the current user
bezl.env.properties.<custom property name> = the custom property for the user identified by the name
