Public bug reported:
Binary package hint: krb5-user
The obvious use case is a user does something silly such as:
sudo kinit -p <principal> and promptly makes a root:root ccache file for
the specified principal.
Then the user later tries to kinit as that user and in fact everything
*looks* fine...the kinit doesn't print any errors and returns 0.
However the truth is nothing was done because the ccache is the wrong
permissions.
klist prints an error well enough:
klist: Credentials cache permissions incorrect while setting cache flags
(ticket cache FILE:/var/run/ccache/krb5cc_45531_DIPCWB)
