I have a two part question that I can't seem to find a good answer for, besides that it does it and check the nonexistent documentation on the subject.

What are the variables to use in the path settings of the home directory environmental setup. Since I'm using templates I'm guessing %userid% wouldn't work so well. \data\users\"user_id_of_template_target".

Second, since I'm getting into this late, if I set a valid home path in the user template will it go back through and create all the missing home directories for users already assigned to the template or just newly created users.
