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 ipropd-master
|
|
is used to propagate changes to a Heimdal Kerberos database from the
|
|
master Kerberos server on which it runs to slave Kerberos servers
|
|
running
|
|
.Nm ipropd-slave .
|
|
.Pp
|
|
The slaves are specified by the contents of the
|
|
.Pa slaves
|
|
file in the KDC's database directory, e.g.\&
|
|
.Pa /var/heimdal/slaves .
|
|
This has principals one per-line of the form
|
|
.Dl iprop/ Ns Ar slave Ns @ Ns Ar REALM
|
|
where
|
|
.Ar slave
|
|
is the hostname of the slave server in the given
|
|
.Ar REALM ,
|
|
e.g.\&
|
|
.Dl iprop/kerberos-1.example.com@EXAMPLE.COM
|
|
On a slave, the argument
|
|
.Fa master
|
|
specifies the hostname of the master server from which to receive updates.
|
|
.Pp
|
|
In contrast to
|
|
.Xr hprop 8 ,
|
|
which sends the whole database to the slaves regularly,
|
|
.Nm
|
|
normally sends only the changes as they happen on the master.
|
|
The master keeps track of all the changes by assigning a version
|
|
number to every change to the database.
|
|
The slaves know which was the latest version they saw, and in this
|
|
way it can be determined if they are in sync or not.
|
|
A log of all the changes is kept on the master.
|
|
When a slave is at an older version than the oldest one in the log,
|
|
the whole database has to be sent.
|
|
.Pp
|
|
The changes are propagated over a secure channel (on port 2121 by
|
|
default).
|
|
This should normally be defined as
|
|
.Dq iprop/tcp
|
|
in
|
|
.Pa /etc/services
|
|
or another source of the services database.
|
|
The master and slaves
|
|
must each have access to a keytab with keys for the
|
|
.Nm iprop
|
|
service principal on the local host.
|
|
.Pp
|
|
There is a keep-alive feature logged in the master's
|
|
.Pa slave-stats
|
|
file (e.g.\&
|
|
.Pa /var/heimdal/slave-stats ) .
