 77  .Sh DESCRIPTION
 78  .Nm
 79  takes a principal database in a specified format and converts it into
 80  a stream of Heimdal database records. This stream can either be
 81  written to standard out, or (more commonly) be propagated to a
 82  .Xr hpropd 8
 83  server running on a different machine.
 84  .Pp
 85  If propagating, it connects to all
 86  .Ar hosts
 87  specified on the command by opening a TCP connection to port 754
 88  (service hprop) and sends the database in encrypted form.
 89  .Pp
 90  Supported options:
 91  .Bl -tag -width Ds
 92  .It Fl m Ar file , Fl Fl master-key= Ns Pa file
 93  Where to find the master key to encrypt or decrypt keys with.
 94  .It Fl d Ar file , Fl Fl database= Ns Pa file
 95  The database to be propagated.
 96  .It Fl Fl source= Ns Ar heimdal|mit-dump|krb4-dump|kaserver
 97  Specifies the type of the source database. Alternatives include:
 98  .Pp
 99  .Bl -tag -width mit-dump -compact -offset indent
100  .It heimdal
101  a Heimdal database
102  .It mit-dump
103  a MIT Kerberos 5 dump file
104  .El
105  +.It Fl k Ar keytab , Fl Fl keytab= Ns Ar keytab
106  The keytab to use for fetching the key to be used for authenticating
107  to the propagation daemon(s). The key
108  .Pa hprop/hostname
109  is used from this keytab.  The default is to fetch the key from the
110  KDC database.
111  .It Fl R Ar string , Fl Fl v5-realm= Ns Ar string
112  Local realm override.
113  .It Fl D , Fl Fl decrypt
114  The encryption keys in the database can either be in clear, or
115  encrypted with a master key. This option transmits the database with
116  unencrypted keys.
117  .It Fl E , Fl Fl encrypt
118  This option transmits the database with encrypted keys.
119  .It Fl n , Fl Fl stdout
120  Dump the database on stdout, in a format that can be fed to hpropd.
121  .El
122  .Sh EXAMPLES
123  The following will propagate a database to another machine (which
124  should run
125  .Xr hpropd 8 ) :
126  .Bd -literal -offset indent
127  $ hprop slave-1 slave-2
