The day before I tried to fix a "Time went backwards" problem on our xen domU's. I tried to set /sys/.../clocksource0/ current_clocksource to "jiffies" instead of "xen" and hoped for the problem to vanish. What I got was strange: after this modification our kerberos server randomly decided to reject repeated authentication requests: # testsaslauthd -u ralf -p <pwd> -R 10 0: OK "Success." 1: NO "authentication failed" 2: NO "authentication failed" 3: NO "authentication failed" 4: NO "authentication failed" 5: OK "Success." 6: NO "authentication failed" 7: NO "authentication failed" 8: NO "authentication failed" 9: NO "authentication failed" the corresponding log in /var/log/messages: Jan 9 18:56:21 krb5 saslauthd[3127]: auth_krb5: k5support_verify_tgt Jan 9 18:56:21 krb5 saslauthd[3127]: do_auth: auth failure: [user=ralf] [service=imap] [realm=] [mech=kerberos5] [reason=saslauthd internal error] and /var/log/krb5/krb5kdc.log Jan 09 18:58:50 krb5 krb5kdc[2916](info): DISPATCH: repeated (retransmitted?) request from ... After I switched back to clocksource=xen I found that the same error occurs in the traditional setup but much less frequent (1 out of 10 instead of 8 out of 10). Does anybody has an idea what happens here? The system is an opensuse 11.0 domU on a 11.0 dom0.
