Too dumb to mount as non privileged user

[norbert at akumakun.de]

Hello,

using a 6.2-PRERELEASE I am not able to let a normal user mount a cdrom.
I have tried the following:

o vfs.usermount=1 to sysctl.conf
o added group usermounters
o added user to usermounters
o own acd0 root:usermounters to devfs.conf
o perm acd0 0660 to devfs.conf
o created directory with ownership of non privileged user
o reboot

Trying to mount as user to the users own directory yields 'operation not permitted' error.

So I changed the ownerships to 0666 but this didn't help either.
I doublechecked sysctl, groups and ownerships. Can please anybody give me a hint?

TIA

Norbert
