HowTos for users
Every student should use the shorcut on their Desktop, which should point to something like https://ldap/lwat/chguserpw.php?username=$(id -un). (On Windows they have to manually put in their username.)
Using lwat to change their password, ensures that linux (userPassword) and samba (sabmaNTPassword and smbaLMPassword) passwords are the same.
Changing the sound volume
On local machines, which are workstations and LTSP servers, and diskless workstations, kmix works as usual. alsamixer can also be used to change the sound volume.
On thin clients, pavucontrol works, and so does alsamixer but kmix does not work at all.
