Is there a reason PAM is case sensitive wrt user names? We set up user names in all uppercase in the Framework User Manager. When logging in with lowercase names, the user is authenticated but not authorized for any consoles so the PAM Framework Console doesn't show any logins. Furthermore, when trying to run something like "usrun shell" on a UNIX server for privileged shell access, unless the user's lowercase name is in a User Group, the command fails.
Why doesn't PAM just ignore the case of a user to avoid all of this?
