KPROPD(8) MIT Kerberos KPROPD(8)
NAME
kpropd - Kerberos V5 replica KDC update server
SYNOPSIS
kpropd [-r realm] [-A admin_server] [-a acl_file] [-f replica_dumpfile]
[-F principal_database] [-p kdb5_util_prog] [-P port]
[--pid-file=pid_file] [-d] [-t]
DESCRIPTION
The kpropd command runs on the replica KDC server. It listens for
update requests made by the kprop(8) program. If incremental propaga‐
tion is enabled, it periodically requests incremental updates from the
master KDC.
When the replica receives a kprop request from the master, kpropd
accepts the dumped KDC database and places it in a file, and then runs
kdb5_util(8) to load the dumped database into the active database which
is used by krb5kdc(8). This allows the master Kerberos server to use
kprop(8) to propagate its database to the replica servers. Upon a suc‐
cessful download of the KDC database file, the replica Kerberos server
will have an up-to-date KDC database.
Where incremental propagation is not used, kpropd is commonly invoked
out of inetd(8) as a nowait service. This is done by adding a line to
the /etc/inetd.conf file which looks like this:
kprop stream tcp nowait root /usr/local/sbin/kpropd kpropd
kpropd can also run as a standalone daemon, backgrounding itself and
waiting for connections on port 754 (or the port specified with the -P
option if given). Standalone mode is required for incremental propaga‐
tion. Starting in release 1.11, kpropd automatically detects whether
it was run from inetd and runs in standalone mode if it is not. Prior
to release 1.11, the -S option is required to run kpropd in standalone
mode; this option is now accepted for backward compatibility but does
nothing.
Incremental propagation may be enabled with the iprop_enable variable
in kdc.conf(5). If incremental propagation is enabled, the replica
periodically polls the master KDC for updates, at an interval deter‐
mined by the iprop_replica_poll variable. If the replica receives
updates, kpropd updates its log file with any updates from the master.
kproplog(8) can be used to view a summary of the update entry log on
the replica KDC. If incremental propagation is enabled, the principal
kiprop/replicahostname@REALM (where replicahostname is the name of the
replica KDC host, and REALM is the name of the Kerberos realm) must be
present in the replica's keytab file.
kproplog(8) can be used to force full replication when iprop is
enabled.
OPTIONS
-r realm
Specifies the realm of the master server.
-A admin_server
Specifies the server to be contacted for incremental updates; by
default, the master admin server is contacted.
-f file
Specifies the filename where the dumped principal database file
is to be stored; by default the dumped database file is
/var/krb5/from_master.
-p Allows the user to specify the pathname to the kdb5_util(8) pro‐
gram; by default the pathname used is /usr/sbin/kdb5_util.
-d Turn on debug mode. In this mode, kpropd will not detach itself
from the current job and run in the background. Instead, it
will run in the foreground and print out debugging messages dur‐
ing the database propagation.
-t In standalone mode without incremental propagation, exit after
one dump file is received. In incremental propagation mode,
exit as soon as the database is up to date, or if the master
returns an error.
-P Allow for an alternate port number for kpropd to listen on.
This is only useful in combination with the -S option.
-a acl_file
Allows the user to specify the path to the kpropd.acl file; by
default the path used is /var/krb5/kpropd.acl.
--pid-file=pid_file
In standalone mode, write the process ID of the daemon into
pid_file.
ENVIRONMENT
kpropd uses the following environment variables:
· KRB5_CONFIG
· KRB5_KDC_PROFILE
FILES
kpropd.acl
Access file for kpropd; the default location is
/usr/local/var/krb5kdc/kpropd.acl. Each entry is a line con‐
taining the principal of a host from which the local machine
will allow Kerberos database propagation via kprop(8).
ENVIRONMENT
See kerberos(7) for a description of Kerberos environment variables.

NOTES
The kprop service is managed by the service management facility,
smf(7), under the service identifier:
svc:/network/security/krb5_prop:default
Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using svcadm(8). The service's
status can be queried using the svcs(1) command.
