+.SH DESCRIPTION
+.I kpropd 
+is the server which accepts connections from the 
+.IR kprop (8)
+program.  
+.I kpropd 
+accepts the dumped KDC database and places it in a file, and then runs 
+.IR kdb5_edit (8)
+to load the dumped database into the active database which is used by 
+.IR krb5kdc (8).
+Thus, the master Kerberos server can use 
+.IR kprop (8)
+to propagate its database to the slave slavers.  Upon a successful download 
+of the KDC database file, the slave Kerberos server will have an
+up-to-date KDC database. 
+.PP
+The
+.B \-r
+.I realm
+option specifies the realm of the master server; by default the realm
+returned by 
+.IR krb5_default_local_realm (3)
+is used.
+.PP
+The
+.B \-f
+.I file
+option specifies the filename where the dumped principal database file
+is to be stored; by default the dumped database file is KPROPD_DEFAULT_FILE
+(normally /krb5/from_master).
+.PP
+The 
+.B \-p
+option allows the user to specify the pathname to the 
+.IR kdb5_edit (8)
+program; by default the pathname used is KPROPD_DEFAULT_KDB5_EDIT
+(normally /krb5/bin/kdb5_edit).
+.PP
+The
+.B \-S
+option turns on standalone mode.  Normally, kpropd is invoked out of
+.IR inetd (8)
+and so it expects a network connection to be passed to it from
+.I inetd (8).
+If the 
+.B \-S 
+option is specified, kpropd will put itself into the background, and
+wait for connections to the KPROP_SERVICE port (normally krb5_prop).
+.PP
+The
+.B \-d
+option turns on debug mode.  In this mode, if the 
+.B \-S 
+option is selected, 
+.I kpropd
+will not detach itself from the current job and run in the background.
+Instead, it will run in the foreground and print out debugging
+messages during the database propagation.
