First of all, I would like to thank the following kind Sun Managers
for sharing their insight:
Rorz Chisholm rchishol@math.ethz.ch
Stephen Harris sweh@mpn.com
Casper Dik casper@holland.Sun.COM
Ronald Hello hello@cs.utwente.nl
The cause of my problem is that I had followed the Answerbook too
faithfully, so I had a nosuid in the /etc/auto_master. After removing
the option and restarting the automountd, everything worked.
Many thanks again to the four Sun Managers listed above.
Regards,
Chin Fang
