 Kerberos 5 Release 1.19 is now available

The MIT Kerberos Team announces the availability of the krb5-1.19 release. The detached PGP signature is available without going through the download page, if you wish to verify the authenticity of a distribution you have obtained elsewhere.

Please see the README file for a more complete list of changes.

You may also see the current full list of fixed bugs tracked in our RT bugtracking system.
Triple-DES transition

Beginning with the krb5-1.19 release, a warning will be issued if initial credentials are acquired using the des3-cbc-sha1 encryption type. In future releases, this encryption type will be disabled by default and eventually removed.

Beginning with the krb5-1.18 release, single-DES encryption types have been removed.
Major changes in 1.19 (2021-02-01)

Administrator experience

        When a client keytab is present, the GSSAPI krb5 mech will refresh credentials even if the current credentials were acquired manually.
        It is now harder to accidentally delete the K/M entry from a KDB. 

Developer experience

        gss_acquire_cred_from() now supports the "password" and "verify" options, allowing credentials to be acquired via password and verified using a keytab key.
        When an application accepts a GSS security context, the new GSS_C_CHANNEL_BOUND_FLAG will be set if the initiator and acceptor both provided matching channel bindings.
        Added the GSS_KRB5_NT_X509_CERT name type, allowing S4U2Self requests to identify the desired client principal by certificate.
        PKINIT certauth modules can now cause the hw-authent flag to be set in issued tickets.
        The krb5_init_creds_step() API will now issue the same password expiration warnings as krb5_get_init_creds_password(). 

Protocol evolution

        Added client and KDC support for Microsoft's Resource-Based Constrained Delegation, which allows cross-realm S4U2Proxy requests. A third-party database module is required for KDC support.
        kadmin/admin is now the preferred server principal name for kadmin connections, and the host-based form is no longer created by default. The client will still try the host-based form as a fallback.
        Added client and server support for Microsoft's KERB_AP_OPTIONS_CBT extension, which causes channel bindings to be required for the initiator if the acceptor provided them. The client will send this option if the client_aware_gss_bindings profile option is set. 

User experience

        kinit will now issue a warning if the des3-cbc-sha1 encryption type is used in the reply. This encryption type will be deprecated and removed in future releases.
        Added kvno flags --out-cache, --no-store, and --cached-only (inspired by Heimdal's kgetcred).
