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).
