Description of problem:
Seems to correlate with having accessed the box via SSH earlier.
SELinux is preventing /usr/sbin/sshd from 'entrypoint' accesses on the file /usr/lib64/security/pam_krb5/pam_krb5_cchelper.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that sshd should be allowed entrypoint access on the pam_krb5_cchelper file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep sshd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
