NAME

     ktutil -- manage Kerberos keytabs

SYNOPSIS

     ktutil [-k keytab | --keytab=keytab] [-v | --verbose] [--version] [-h | --help] command [args]

DESCRIPTION

     ktutil is a program for managing keytabs.	Supported options:

     -v, --verbose
	     Verbose output.

     command can be one of the following:

     add [-p principal] [--principal=principal] [-V kvno] [--kvno=kvno] [-e enctype] [--enctype=enctype] [-w password] [--password=password] [-r]
		 [--random] [-s] [--no-salt] [-H] [--hex]
		 Adds a key to the keytab. Options that are not specified will be prompted for. This requires that you know the password or the
		 hex key of the principal to add; if what you really want is to add a new principal to the keytab, you should consider the get
		 command, which talks to the kadmin server.

     change [-r realm] [--realm=realm] [--a host] [--admin-server=host] [--s port] [--server-port=port]
		 Update one or several keys to new versions.  By default, use the admin server for the realm of a keytab entry.  Otherwise it will
		 use the values specified by the options.

		 If no principals are given, all the ones in the keytab are updated.

     copy keytab-src keytab-dest
		 Copies all the entries from keytab-src to keytab-dest.

     get [-p admin principal] [--principal=admin principal] [-e enctype] [--enctypes=enctype] [-r realm] [--realm=realm] [-a admin server]
		 [--admin-server=admin server] [-s server port] [--server-port=server port] principal ...
		 For each principal, generate a new key for it (creating it if it doesn't already exist), and put that key in the keytab.

		 If no realm is specified, the realm to operate on is taken from the first principal.

     list [--keys] [--timestamp]
		 List the keys stored in the keytab.

     remove [-p principal] [--principal=principal] [-V -kvno] [--kvno=kvno] [-e -enctype] [--enctype=enctype]
		 Removes the specified key or keys. Not specifying a kvno removes keys with any version number. Not specifying an enctype removes
		 keys of any type.

     rename from-principal to-principal
		 Renames all entries in the keytab that match the from-principal to to-principal.

     purge [--age=age]
		 Removes all old versions of a key for which there is a newer version that is at least age (default one week) old.

NAME

       ipa-rmkeytab - Remove a kerberos principal from a keytab

SYNOPSIS

       ipa-rmkeytab [ -p principal-name ] [ -k keytab-file ] [ -r realm ] [ -d ]

DESCRIPTION

       Removes a kerberos principal from a keytab.

       Kerberos  keytabs  are  used  for  services (like sshd) to perform kerberos authentication. A keytab is a file with one or more secrets (or
       keys) for a kerberos principal.

       A kerberos service principal is a kerberos identity that can be used for authentication. Service principals contain the name  of  the  ser-
       vice, the hostname of the server, and the realm name.

       ipa-rmkeytab  provides  two  ways  to  remove  principals.   A specific principal can be removed or all principals for a given realm can be
       removed.

       All encryption types and versions of a principal are removed.

       The realm may be included when removing a specific principal but it is not required.

       NOTE: removing a principal from the keytab does not affect the Kerberos principal stored in the IPA server. It  merely  removes	the  entry
       from the local keytab.

OPTIONS

       -p principal-name
	      The non-realm part of the full principal name.

       -k keytab-file
	      The keytab file to append the principal(s) from.

       -r realm
	      A realm to remove all principals for.

       -d     Debug mode. Additional information is displayed.

EXAMPLES

       Remove the NFS service principal on the host foo.example.com from /tmp/nfs.keytab.

	  # ipa-rmkeytab -p nfs/foo.example.com -k /tmp/nfs.keytab

       Remove the ldap service principal on the host foo.example.com from /etc/krb5.keytab.

	  # ipa-rmkeytab -p ldap/foo.example.com -k /etc/krb5.keytab

       Remove all principals for the realm EXAMPLE.COM.

	 # ipa-rmkeytab -r EXAMPLE.COM -k /etc/krb5.keytab

EXIT STATUS

       The exit status is 0 on success, nonzero on error.

       1 Kerberos initialization failed

       2 Memory allocation error

       3 Unable to open keytab

       4 Unable to parse the principal name

       5 Principal name or realm not found in keytab

       6 Unable to remove principal from keytab
