kprop(1M) System Administration Commands kprop(1M)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(1M).
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.
