NAME
       krb5kdc - Kerberos V5 KDC

SYNOPSIS
       krb5kdc [ -d dbname ] [ -k keytype ] [ -M mkeyname ] [ -p portnum ] [ -m ] [ -r realm ] [ -4 v4mode ]

DESCRIPTION
       krb5kdc is the Kerberos version 5 Authentication Service and Key Distribution Center (AS/KDC).

       The   -r   realm   option  specifies  the  realm  for  which  the  server  should  provide  service;  by  default  the  realm  returned	by
       krb5_default_local_realm(3) is used.

       The -d dbname option specifies the name under which the principal database can be found; by default the database is in DEFAULT_DBM_FILE.

       The -k keytype option specifies the key type of the master key in the database; the default is KEYTYPE_DES.

       The -M mkeyname option specifies the principal name for the master key in the database; the default is KRB5_KDB_M_NAME  (usually  "K/M"	in
       the KDC's realm).

       The  -p portnum option specifies the default UDP port number which the KDC should listen on for Kerberos version 5 requests.  This value is
       used when no port is specified in the KDC profile and when no port is specified in the Kerberos configuration file.  If no value is  avail-
       able, then the value in /etc/services for service "kerberos" is used.

       The -m option specifies that the master database password should be fetched from the keyboard rather than from a file on disk.

       The  -4	option specifies how the KDC responds to kerberos IV requests for tickets.  The command line option overrides the value in the KDC
       profile.  The possible values are none, disable, full or nopreauth.  These instruct the KDC to not respond to V4 packets, to respond with a
       version skew error, to issue tickets for all database entries, and to issue tickets for all but preauthentication required database entries
       respectively. The default behaviour is as if nopreauth was specified.

       The KDC may service requests for multiple realms (maximum 32 realms).  The realms are listed on the command line.  Per-realm  options  that
       can  be	specified  on  the  command  line  pertain for each realm that follows it and are superceded by subsequent definitions of the same
       option.	For example,

       krb5kdc -p 2001 -r REALM1 -p 2002 -r REALM2 -r REALM3

       specifies that the KDC listen on port 2001 for REALM1 and on port 2002 for REALM2 and REALM3.  Additionally, per-realm  parameters  may	be
       specified in the kdc.conf file.	The location of this file may be specified by the KRB5_KDC_PROFILE environment variable.  Parameters spec-
       ified in this file take precedence over options specified on the command line.  See the kdc.conf(5) description for further details.

BUGS
       It should fork and go into the background when it finishes reading the master password from the terminal.
