[Bug 740477] [NEW] kinit should print an error if credentials cache has invalid permissions

[Alec Warner]

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)
