K5SRVUTIL(1)			 MIT Kerberos			  K5SRVUTIL(1)

NAME
       k5srvutil - host	key table (keytab) manipulation	utility

SYNOPSIS
       k5srvutil operation [-i]	[-f filename] [-e keysalts]

DESCRIPTION
       k5srvutil  allows  an administrator to list keys	currently in a keytab,
       to obtain new keys for a	principal currently in a keytab, or to	delete
       non-current keys	from a keytab.

       operation must be one of	the following:

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

       change Uses  the	 kadmin	 protocol  to  update the keys in the Kerberos
	      database to new randomly-generated keys, and updates the keys in
	      the keytab to match.  If a key's version	number	doesn't	 match
	      the  version  number  stored  in the Kerberos server's database,
	      then the operation will fail.  If	the -i flag is given,  k5srvu-
	      til  will	 prompt	for confirmation before	changing each key.  If
	      the -k option is given, the old and new keys will	be  displayed.
	      Ordinarily,  keys	 will be generated with	the default encryption
	      types and	key salts.  This can be	overridden with	the -e option.
	      Old keys are retained in the keytab  so  that  existing  tickets
	      continue	to  work, but delold should be used after such tickets
	      expire, to prevent attacks against the old keys.

       delold Deletes keys that	are not	 the  most  recent  version  from  the
	      keytab.	This operation should be used some time	after a	change
	      operation	to remove old keys, after existing tickets issued  for
	      the service have expired.	 If the	-i flag	is given, then k5srvu-
	      til will prompt for confirmation for each	principal.

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

       In all cases, the default keytab	is used	unless this is	overridden  by
       the -f option.

       k5srvutil uses the kadmin(1) program to edit the	keytab in place.
