NAME

kprop - Kerberos database propagation program

SYNOPSIS

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

DESCRIPTION

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 KDCs.

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 kdb5_util(8).

OPTIONS

The following options are supported:

-d
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
/etc/krb5/krb5.keytab.

OPERANDS

The following operands are supported:

host
Name of the slave KDC.

EXAMPLES

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

FILES

/etc/krb5/kpropd.acl
List of principals of all the KDCs;
resides on each slave KDC.

/etc/krb5/krb5.keytab
Keytab for Kerberos clients.

/var/krb5/slave_datatrans
Kerberos database propagated to the KDC
slaves.
