no permission as root?

[Die Optimisten <inform@die-optimisten.net>]

Hi
I#m using normal Debian, without virtualization, etc
Why do I have access as user, but not as root????


tmp is tmpfs

softlink as User:
/tmp/X$ ln -s /mnt/A4/TmpTmp-Anschauen/RRÖ/ RR  # as User
root@PcDach:/tmp/X# dir RR/     # as Root
ls: cannot access RR/: Permission denied

root@PcDach:/tmp/X# rm RR
rm: remove symbolic link `RR'? y
root@PcDach:/tmp/X# ln -s /mnt/A4/TmpTmp-Anschauen/RRÖ/ RR
root@PcDach:/tmp/X# dir RR      # works

Version:
Linux RR 3.2.0-4-amd64 #1 SMP Debian 3.2.68-1+deb7u6 x86_64 GNU/Linux


thank you
Andrew
