Maybe it's not in newer release of openssh?
RHEL8 is using:
$ rpm -q openssh-server
openssh-server-8.0p1-13.el8.x86_64
And from the man page:
KerberosUniqueCCache
Specifies whether to store the acquired tickets in the
per-session credential cache under /tmp/ or whether to use
per-user credential cache as configured in /etc/krb5.conf.
The default value no can lead to overwriting previous
tickets by subseqent connections to the same user account.
And this gets a bit interesting depending on what's in /etc/krb5.conf
and if using sssd what's in sssd.conf for kerberos.
Thanks.
