kprop - Kerberos database propagation program


/usr/lib/krb5/kprop [-d] [-f file] [-p port-number]
[-r realm] [-s keytab] [host]


kprop is a command-line utility used for propagating a Kerberos database
from a master KDC to a slave KDC. This command must be run on the master
KDC. See the Solaris System Administration Guide, Vol. 6 on how to set up
periodic propagation between the master KDC and slave KDCs.

To propagate a Kerberos database, the following conditions must be met:

o The slave KDCs must have an /etc/krb5/kpropd.acl file that
contains the principals for the master KDC and all the slave

o A keytab containing a host principal entry must exist on each
slave KDC.

o The database to be propagated must be dumped to a file using


The following options are supported:

Enable debug mode. Default is debug mode disabled.

-f file
File to be sent to the slave KDC. Default is the
/var/krb5/slave_datatrans file.

-p port-number
Propagate port-number. Default is port 754.

-r realm
Realm where propagation will occur. Default realm is
the local realm.

-s keytab
Location of the keytab. Default location is


The following operands are supported:

Name of the slave KDC.


Example 1: Propagating the Kerberos Database

The following example propagates the Kerberos database from the
/tmp/slave_data file to the slave KDC london. The machine london must
have a host principal keytab entry and the kpropd.acl file must contain
an entry for the all the KDCs.

# kprop -f /tmp/slave_data london


List of principals of all the KDCs; resides
on each slave KDC.

Keytab for Kerberos clients.
