NAME

       k5srvutil - host key table (keytab) manipulation utility

SYNOPSIS

       k5srvutil operation [-i] [-f filename]

DESCRIPTION

       k5srvutil allows an administrator to list or change keys currently in a keytab or to add new keys to the 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.   Old  keys  are  retained in the keytab so that existing tickets continue to work.  If the -i flag is given,
	      k5srvutil will prompt for confirmation before changing each key.	If the -k option is given, the old and new keys will be displayed.

       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 k5srvutil 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.
