80 takes a principal database in a specified format and converts it into
81 a stream of Heimdal database records. This stream can either be
82 written to standard out, or (more commonly) be propagated to a
84 server running on a different machine.
86 If propagating, it connects to all
88 specified on the command by opening a TCP connection to port 754
89 (service hprop) and sends the database in encrypted form.
95 .Fl -master-key= Ns Pa file
97 Where to find the master key to encrypt or decrypt keys with.
100 .Fl -database= Ns Pa file
102 The database to be propagated.
104 .Fl -source= Ns Ar heimdal|mit-dump|krb4-dump|kaserver
106 Specifies the type of the source database. Alternatives include:
108 .Bl -tag -width krb4-dump -compact -offset indent
112 a MIT Kerberos 5 dump file
114 a Kerberos 4 dump file
116 an AFS kaserver database
120 .Fl -keytab= Ns Ar keytab
122 The keytab to use for fetching the key to be used for authenticating
123 to the propagation daemon(s). The key
125 is used from this keytab. The default is to fetch the key from the
129 .Fl -v5-realm= Ns Ar string
131 Local realm override.
136 The encryption keys in the database can either be in clear, or
137 encrypted with a master key. This option transmits the database with
143 This option transmits the database with encrypted keys.
148 Dump the database on stdout, in a format that can be fed to hpropd.
151 The following options are only valid if
153 is compiled with support for Kerberos 4 (kaserver).
157 .Fl -v4-realm= Ns Ar string
162 .Fl -cell= Ns Ar cell
164 The AFS cell name, used if reading a kaserver database.
169 Also dump the principals marked as special in the kaserver database.
