According to keyctl, the krenew started from an /opt/kde3/env shell
script is in the right PAG. And krenew does call aklog, and aklog is
able to update my token successfully. Great! So the problem was
My best guess now is that krenew was not working because winbind was set
to renew my kerberos ticket, and did so apparently every 5 hours. Krenew
was happily waiting forever for the Kerberos ticket (with an expiration
time of 10 hours) to expire within the next hour, and did not bother to
update my AFS tokens (which did expire!).
I guess now that if I want to use krenew for multiple logins, I should
not use (a shared) /tmp/krb5cc_xxxx either?
Anyway, thanks for your suggestions, they really helped me to verify my
KDE krenew setup.
