NAME

       krb5kdc - KDC daemon

SYNOPSIS

       /usr/lib/krb5/krb5kdc [-d dbpath] [-r realm]  [-m]
	    [-k masterenctype] [-M masterkeyname]
	    [-p port] [-n] [-x db_args]...

DESCRIPTION

       krb5kdc	is  the  daemon that runs on the master and slave KDCs to process the Kerberos tickets. For Kerberos to function properly, krb5kdc
       must be running on at least one KDC that the Kerberos clients can access. Prior to running krb5kdc, you must initialize the Kerberos  data-
       base using kdb5_util(1M). See the  for information regarding how to set up KDCs and initialize the Kerberos database.

OPTIONS

       The following options are supported:

       -d dbpath

	   Specify the path to the database; default value is /var/krb5.

       -k masterenctype

	   Specify  the  encryption  type for encrypting the database. The default value is des-cbc-crc. des3-cbc-sha1, arcfour-hmac-md5, arcfour-
	   hmac-md5-exp, aes128-cts-hmac-sha1-96, and aes256-cts-hmac-sha1-96 are also valid.

       -m

	   Specify that the master key for the database is to be entered manually.

       -M masterkeyname

	   Specify the principal to retrieve the master Key for the database.

       -n

	   Specify that krb5kdc should not detach from the terminal.

       -p port

	   Specify the port that will be used by the KDC to listen for incoming requests.

       -r realm

	   Specify the realm name; default is the local realm name.

       -x db_args

	   Pass database-specific arguments to kadmin. Supported arguments are for the LDAP plug-in. These arguments are:

	   binddn=binddn

	       Specifies the DN of the object used by the KDC server to bind to the LDAP server. This object should have the rights  to  read  the
	       realm  container,  principal container and the subtree that is referenced by the realm. Overrides the ldap_kdc_dn parameter setting
	       in krb5.conf(4).

	   bindpwd=bindpwd

	       Specifies the password for the above-mentioned binddn. It is recommended not to use this  option.  Instead,  the  password  can	be
	       stashed using the stashsrvpw command of kdb5_ldap_util(1M).

	   nconns=num

	       Specifies the number of connections to be maintained per LDAP server.

	   host=ldapuri

	       Specifies, by an LDAP URI, the LDAP server to which to connect.

FILES

       /var/krb5/principal.db

	   Kerberos principal database.

       /var/krb5/principal.kadm5

	   Kerberos administrative database. This file contains policy information.

       /var/krb5/principal.kadm5.lock

	   Kerberos  administrative  database  lock  file. This file works backwards from most other lock files (that is, kadmin will exit with an
	   error if this file does not exist).

       /etc/krb5/kdc.conf

	   KDC configuration file. This file is read at startup.

       /etc/krb5/kpropd.acl

	   File that defines the access control list for propagating the Kerberos database using kprop.

NOTES

       The following signal has the specified effect when sent to the server process using the kill(1)command:

       SIGHUP

	   krb5kdc  closes  and  re-opens  log	files  that  it  directly  opens.  This  can be useful for external log-rotation utilities such as
	   logadm(1M). If this method is used for log file rotation, set the krb5.conf(4) kdc_rotate period relation to never.
