The problem here is that the Mach-IPC based CCacheServer (which
stores your tickets) gets registered as root by launchd. There is
special code in the login process which tells the first instantiation
of the CCacheServer to run as the user. However when you destroy
your tickets and get new ones, launchd launches the second
CCacheServer (and all future ones) as root and thus you don't have
access to your ticket cache.
Apple is aware of this problem and is working with MIT to resolve
it. Unfortunately there is currently no workaround other than to not
enable Kerberos at login.

Has anyone run into this?
We have edited /etc/authorization and set
builtin:krb5authenticate,privileged in place of authinternal for
system.login.console. This allows us to log into the system with a
valid Kerberos password.
However, in 10.4.2 when we run kdestroy, kinit will no longer work:
drwmac:~ drwachd$ /usr/bin/klist
Kerberos 5 ticket cache: 'API:Initial default ccache'
Default principal: [EMAIL PROTECTED]
Valid Starting Expires Service Principal

krbtgt/[EMAIL PROTECTED]
renew until 08/02/05 11:20:42
klist: No Kerberos 4 tickets in credentials cache
drwmac:~ drwachd$ /usr/bin/kdestroy
drwmac:~ drwachd$ /usr/bin/kinit
Please enter the password for [EMAIL PROTECTED]:
Kerberos Login Failed: Credentials cache server unavailable
drwmac:~ drwachd$
If we login with a local (not Kerberos) password, type kinit then
kdestroy, then kinit - it works fine.
Any ideas as to the problem?
