Hi @yerenkow. Thanks for your PR.

I'm waiting for a kubernetes-csi member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Adding support for sec=krb5 mounting
d9aa489 
When mounting with kerberos security, ticket cache
is expected to be set up on the host, pointing to the
/var/lib/kubelet/kubernetes/krb5cc_${uid}.
Credential cache is then taken from the creds secret and
written to the file, that is available to the host for
using.

@yerenkow when the kerberos ticket is expired, how does this driver handle this issue? do we need to unmount the pv and mount again?
