Support KCM credential caches
Last modified: 2020-02-07 18:20:53 UTC
MIT Kerberos is introducing a new credentials cache type called "KCM" that will store the tickets in SSSD. As of today, libkrb5 already supports KCM credentials, and there is ongoing work to support this in SSSD. "KCM" caches offer notifications via D-Bus signals. This will most likely be finished and introduced in Fedora 27.
Even though KCM caches are now a reality in SSSD, and the default in Fedora 27, there is still no notification API: https://pagure.io/SSSD/sssd/issue/3568
Supporting KCM caches didn't require any code changes because they use the same code paths as KEYRING caches.
