fl_teachertool will not work properly for non root users. You have to
setup visudo for teachers as described here

Also if you run it as root make sure you become root like this

Are you talking about specifically with fl_teachertool or in general?
I don't have LDAP experience maybe someone else can help here.

Are you wanting teachers to access student homes so they can mark
stuff? If that's the case, I would recommend handin folders where
students (others) only have write and execute permission with the
sticky bit set but the teacher has full access.

Glad to hear it. I enjoy using it too.
