The type prefix is used, if set; the default is currently to FILE:, but
might conceivably change in the future if someone decides that gratuitous
breakage is a good idea.

It's far from clear that the KEYRING: cache type is desired here, and even
if it is, the userspace settings still need to be present just as they
would be for, e.g., a FILE: cache type.

A residual KRB5CCNAME in the environment of the OP's shell might explain
the symptoms; the KRB5_TRACE output from kinit would be useful to see
what's going on.
