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.

@section Migration from MIT Kerberos to Heimdal
|
|
|
|
hpropd can read MIT Kerberos dump, the format is the same as used in
|
|
mit-kerberos 1.0b7, and to dump that format use the following command:
|
|
@samp{kdb5_util dump -b7}.
|
|
|
|
To load the MIT Kerberos dump file, use the following command:
|
|
|
|
@samp{/usr/heimdal/libexec/hprop --database=dump-file --master-key=/var/db/krb5kdc/mit_stash --source=mit-dump --decrypt --stdout | /usr/heimdal/libexec/hpropd --stdin}

@section General issues
|
|
|
|
When migrating from a Kerberos 4 KDC.
|
|
|
|
@section Order in what to do things:
|
|
|
|
@itemize @bullet
|
|
|
|
@item Convert the database, check all principals that hprop complains
|
|
about.
|
|
|
|
@samp{hprop -n --source=<NNN>| hpropd -n}
|
|
|
|
Replace <NNN> with whatever source you have, like krb4-db or krb4-dump.
|
|
|
|
@item Run a Kerberos 5 slave for a while.
|
|
|
|
@c XXX Add you slave first to your kdc list in you kdc.
|
|
|
|
@item Figure out if it does everything you want it to.
|
|
|
|
Make sure that all things that you use works for you.
|
|
|
|
@item Let a small number of controlled users use Kerberos 5 tools.
|
|
|
|
Find a sample population of your users and check what programs they use,
|
|
you can also check the kdc-log to check what ticket are checked out.
|
|
|
|
@item Burn the bridge and change the master.
|
|
@item Let all users use the Kerberos 5 tools by default.
|
|
@item Turn off services that do not need Kerberos 4 authentication.
|
|
|
|
Things that might be hard to get away is old programs with support for
|
|
Kerberos 4. Example applications are old Eudora installations using
|
|
KPOP, and Zephyr. Eudora can use the Kerberos 4 kerberos in the Heimdal
|
|
kdc.
