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 /etc/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.
