Are you sure? http://www.coda.cs.cmu.edu/doc/html/manual/x237.html says:

"In addition to the Coda access lists, the three owner bits of the file
mode are used to indicate readability, writability, and executability.
You should use chmod(1) to set the permissions on individual files."

pam_kerberos works, but this isn't relevant. What I want to know is, does
coda grants access if a valid kerberos token is present and does the
kerberos UID match the coda uid - otherwise ls prints false user names?

BTW: http://www.coda.cs.cmu.edu/doc/html/manual/x197.html says a tokes
expires after 25 hours. Is this tunable? How to grant access for system
services like apache? If users have in their home a webspace ~/.www/
which is accessible through http://www.foo.de/~user/. So apache needs a
unlimited token. Is this possible?

Well, cache isn't the right word. I mean the disk cache. I would like to
turn them on and off at runtime like a swap partition.
