several new kerberos related libraries and applications to FreeBSD:
o kgetcred(1) allows one to manually get a ticket for a particular service.
o kf(1) securily forwards ticket to another host through an authenticated
and encrypted stream.
o kcc(1) is an umbrella program around klist(1), kswitch(1), kgetcred(1)
and other user kerberos operations. klist and kswitch are just symlinks
to kcc(1) now.
o kswitch(1) allows you to easily switch between kerberos credentials if
you're running KCM.
o hxtool(1) is a certificate management tool to use with PKINIT.
o string2key(1) maps a password into key.
o kdigest(8) is a userland tool to access the KDC's digest interface.
o kimpersonate(8) creates a "fake" ticket for a service.
We also now install manpages for some lirbaries that were not installed
before, libheimntlm and libhx509.
- The new HEIMDAL version no longer supports Kerberos 4. All users are
recommended to switch to Kerberos 5.
- Weak ciphers are now disabled by default. To enable DES support (used
by telnet(8)), use "allow_weak_crypto" option in krb5.conf.
- libtelnet, pam_ksu and pam_krb5 are now compiled with error on warnings
disabled due to the function they use (krb5_get_err_text(3)) being
deprecated. I plan to work on this next.
- Heimdal's KDC now require sqlite to operate. We use the bundled version
and install it as libheimsqlite. If some other FreeBSD components will
require it in the future we can rename it to libbsdsqlite and use for these
components as well.
- This is not a latest Heimdal version, the new one was released while I was
working on the update. I will update it to 1.5.2 soon, as it fixes some
important bugs and security issues.

.Sh DESCRIPTION
|
|
.Nm
|
|
is a process based credential cache.
|
|
To use it, set the
|
|
.Ev KRB5CCNAME
|
|
enviroment variable to
|
|
.Ql KCM: Ns Ar uid
|
|
or add the stanza
|
|
.Bd -literal
|
|
|
|
[libdefaults]
|
|
default_cc_name = KCM:%{uid}
|
|
|
|
.Ed
|
|
to the
|
|
.Pa /etc/krb5.conf
|
|
configuration file and make sure
|
|
.Nm kcm
|
|
is started in the system startup files.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
daemon can hold the credentials for all users in the system. Access
|
|
control is done with Unix-like permissions. The daemon checks the
|
|
access on all operations based on the uid and gid of the user. The
|
|
tickets are renewed as long as is permitted by the KDC's policy.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
daemon can also keep a SYSTEM credential that server processes can
|
|
use to access services. One example of usage might be an nss_ldap
|
|
module that quickly needs to get credentials and doesn't want to renew
|
|
the ticket itself.
|
|
