NAME

       k5srvutil - host key table (keytab) manipulation utility

SYNOPSIS

       /usr/sbin/k5srvutil operation [-ik] [-f filename]

DESCRIPTION

       The k5srvutil command allows a system manager to list or change keys currently in his keytab or to add new keys to the keytab.

       The operand operation must be one of the following:

       list	 Lists the keys in a keytab, showing version number and principal name.

       change	 Changes  all  the keys in the keytab to new randomly-generated keys, updating the keys in the Kerberos server's database to match
		 those by using the kadmin protocol. If a key's version number does not match the version number stored in the	Kerberos  server's
		 database,  the operation fails. The old keys are retained so that existing tickets continue to work. If the -i flag is specified,
		 k5srvutil prompts for yes or no before changing each key. If the -k option is used, the old and new keys are displayed.

       delold	 Deletes keys that are not the most recent version from the keytab. This operation should be used at some  point  after  a  change
		 operation  to	remove	old  keys.  If the -i flag is specified, k5srvutil asks the user whether the old keys associated with each
		 principal should be removed.

       delete	 Deletes particular keys in the keytab, interactively prompting for each key.

       In all cases, the default keytab file is /etc/krb5.keytab file unless this is overridden by the -f option.

       k5srvutil uses the kadmin(1M) program to edit the keytab in place. However, old keys are retained, so they are available in case  of  fail-
       ure.

OPTIONS

       The following options are supported:

       -f filename    Specify a keytab file other than the default file, /etc/krb5.keytab.

       -i	      Prompts user before changing keys when using the change or delold operands.

       -k	      Displays old and new keys when using the change operand.

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
