Kerberos 5 is a network authentication system which authenticates clients and servers to each other using symmetric key encryption and a trusted third party, the KDC.
- In case the SSSD client authenticates against a Kerberos server (KDC) using a keytab, and the first encryption type the KDC offers is not present in the keytab, the authentication fails. Note that this problem was fixed in a later release of MIT Kerberos.
