Should `kinit` be called for each connection?

[yastanotheruser]

I'm currently having an issue trying to connect a Kafka cluster due to many concurrent blocking calls to sasl_kinit which messes with the VM scheduling, causing various errors in other modules of my app. Couldn't the Kerberos credential cache allow us to reuse the TGT across multiple connections?

oops, I believe I should have opened this issue in the brod_gssapi repo

Hi @yastanotheruser
Good point.
I think it's worth testing to findout.
e.g. use a persisten_term to cache init state after ok is returned from kinit.

I discovered that my use case doesn't require kinit at all. The important part is that the user already has an active ccache (can be seen using klist). Note that it took a small change to this library to make the default ccache visible, See #41
