takes a principal database in a specified format and converts it into a stream of Heimdal database records. This stream can either be written to standard out, or (more commonly) be propagated to a hpropd() server running on a different machine.

If propagating, it connects to all hosts specified on the command by opening a TCP connection to port 754 (service hprop) and sends the database in encrypted form.

Supported options:

Xo

-m file , --master-key= Ns file Where to find the master key to encrypt or decrypt keys with.

Xo

-d file , --database= Ns file The database to be propagated.

Xo

--source= Ns heimdal|mit-dump|krb4-dump|krb4-db|kaserver Specifies the type of the source database. Alternatives include:

heimdal

a Heimdal database

mit-dump

a MIT Kerberos 5 dump file

krb4-db

a Kerberos 4 database

krb4-dump

a Kerberos 4 dump file

kaserver

an AFS kaserver database

Xo

-k keytab , --keytab= Ns keytab The keytab to use for fetching the key to be used for authenticating to the propagation daemon(s). The key kadmin/hprop is used from this keytab. The default is to fetch the key from the KDC database.

Xo

-R string , --v5-realm= Ns string Local realm override.

Xo

-D , --decrypt The encryption keys in the database can either be in clear, or encrypted with a master key. This option transmits the database with unencrypted keys.

Xo

-E , --encrypt This option transmits the database with encrypted keys.

Xo

-n , --stdout Dump the database on stdout, in a format that can be fed to hpropd.

The following options are only valid if hprop is compiled with support for Kerberos 4 (kaserver).

Xo

-r string , --v4-realm= Ns string v4 realm to use.

Xo

-c cell , --cell= Ns cell The AFS cell name, used if reading a kaserver database.

Xo

-S , --kaspecials Also dump the principals marked as special in the kaserver database.

Xo

-4 , --v4-db Deprecated, identical to

Xo

-K , --ka-db Deprecated, identical to

The following will propagate a database to another machine (which should run hpropd(8) ): $ hprop slave-1 slave-2

Copy a Kerberos 4 database to a Kerberos 5 slave: $ hprop --source=krb4-db -E krb5-slave

Convert a Kerberos 4 dump-file for use with a Heimdal KDC: $ hprop -n --source=krb4-dump -d /var/kerberos/principal.dump --master-key=/.k | hpropd -n
