cdrecord: Keine Berechtigung (-rws--x--x)

[Al Bogner <debian@ml05a.pinguin.uni.cc>]

Bis jetzt reichte es immer die Rechte so zu setzen:
chown root /usr/bin/cdrecord
chmod 4711 /usr/bin/cdrecord

-rws--x--x  1 root root 133 2005-01-09 17:55 /usr/bin/cdrecord

Als root klappt es:

# cdrecord -s -scanbus dev=ATA

Als User habe ich ein Rechte-Problem, das ich unter SuSE nicht 
hatte:

~$ cdrecord -s -scanbus dev=ATA
/usr/bin/cdrecord: /usr/bin/cdrecord: Keine Berechtigung


Nun würde ich gerne wissen, warum das nicht funktoniert. Es ist ja 
das S-Bit gesetzt.
