NAME
       kadmind - KADM5 administration server

SYNOPSIS
       kadmind [-x db_args] [-r realm] [-m] [-nofork] [-proponly] [-port
       port-number] [-P pid_file] [-p kdb5_util_path] [-K kprop_path] [-k
       kprop_port] [-F dump_file]

DESCRIPTION
       kadmind starts the Kerberos administration server.  kadmind typically
       runs on the primary Kerberos server, which stores the KDC database.  If
       the KDC database uses the LDAP module, the administration server and
       the KDC server need not run on the same machine.	 kadmind accepts
       remote requests from programs such as kadmin(1) and kpasswd(1) to
       administer the information in these database.

       kadmind requires a number of configuration files to be set up in order
       for it to work:

       kdc.conf(5)
	      The KDC configuration file contains configuration information
	      for the KDC and admin servers.  kadmind uses settings in this
	      file to locate the Kerberos database, and is also affected by
	      the acl_file, dict_file, kadmind_port, and iprop-related
	      settings.

       kadm5.acl(5)
	      kadmind's ACL (access control list) tells it which principals
	      are allowed to perform administration actions.  The pathname to
	      the ACL file can be specified with the acl_file kdc.conf(5)
	      variable; by default, it is /var/lib/krb5kdc/kadm5.acl.

       After the server begins running, it puts itself in the background and
       disassociates itself from its controlling terminal.

       kadmind can be configured for incremental database propagation.
       Incremental propagation allows replica KDC servers to receive principal
       and policy updates incrementally instead of receiving full dumps of the
       database.  This facility can be enabled in the kdc.conf(5) file with
       the iprop_enable option.	 Incremental propagation requires the
       principal kiprop/PRIMARY\@REALM (where PRIMARY is the primary KDC's
       canonical host name, and REALM the realm name).	In release 1.13, this
       principal is automatically created and registered into the datebase.

OPTIONS

       -r realm
	      specifies the realm that kadmind will serve; if it is not
	      specified, the default realm of the host is used.

       -m     causes the master database password to be fetched from the
	      keyboard (before the server puts itself in the background, if
	      not invoked with the -nofork option) rather than from a file on
	      disk.

       -nofork
	      causes the server to remain in the foreground and remain
	      associated to the terminal.

       -proponly
	      causes the server to only listen and respond to Kerberos replica
	      incremental propagation polling requests.	 This option can be
	      used to set up a hierarchical propagation topology where a
	      replica KDC provides incremental updates to other Kerberos
	      replicas.

       -port port-number
	      specifies the port on which the administration server listens
	      for connections.	The default port is determined by the
	      kadmind_port configuration variable in kdc.conf(5).

       -P pid_file
	      specifies the file to which the PID of kadmind process should be
	      written after it starts up.  This file can be used to identify
	      whether kadmind is still running and to allow init scripts to
	      stop the correct process.

       -p kdb5_util_path
	      specifies the path to the kdb5_util command to use when dumping
	      the KDB in response to full resync requests when iprop is
	      enabled.

       -K kprop_path
	      specifies the path to the kprop command to use to send full
	      dumps to replicas in response to full resync requests.

       -k kprop_port
	      specifies the port by which the kprop process that is spawned by
	      kadmind connects to the replica kpropd, in order to transfer the
	      dump file during an iprop full resync request.

       -F dump_file
	      specifies the file path to be used for dumping the KDB in
	      response to full resync requests when iprop is enabled.

       -x db_args
	      specifies database-specific arguments.  See Database Options in
	      kadmin(1) for supported arguments.

ENVIRONMENT
       See kerberos(7) for a description of Kerberos environment variables.
