NAME
     ktutil - Kerberos keytab maintenance utility

SYNOPSIS
     /usr/bin/ktutil


DESCRIPTION
     The ktutil command is an interactive command-line  interface
     utility  for managing  the keylist in keytab files. You must
     read in a keytab's keylist  before you can manage it.  Also,
     the  user  running  the  ktutil command must have read/write
     permissions on the keytab. For example, if a keytab is owned
     by  root,  which it typically is, ktutil must be run as root
     to have the appropriate permissions.

COMANDS
     clearlist             Clears the current keylist.
     clear

     readkt file           Reads a keytab into the current keyl-
     rkt file               ist.  You  must specify a keytab file
                            to read.


     writekt file          Writes the current keylist to a  key-
     wkt file               tab  file.  You must specify a keytab
                            file to write.  If  the  keytab  file
                            already  exists,  the current keylist
                            is appended to  the  existing  keytab
                            file.


     addentry number       Adds an entry to the current keylist.
     addent number          Specify the entry by the keylist slot
                            number.


     deleteentry number    Deletes an  entry  from  the  current
     delent number          keylist.  Specify  the  entry  by the
                            keylist slot number.


     list                   Lists the current keylist.
     l

     listrequest           Lists available requests (commands).
     lr

                            Exits utility.


EXAMPLES
     Example 1 Deleting a principal from a file


     The following example deletes the host/denver@ACME.com prin-
     cipal  from  the  /etc/krb5/krb5.keytab file. Notice that if
     you want to delete an entry from  an  existing  keytab,  you
     must  first write the keylist to a temporary keytab and then
     overwrite the existing keytab  with  the  temporary  keytab.
     This is because the wkt command actually appends the current
     keylist to an existing  keytab,  so  you  can't  use  it  to
     overwrite a keytab.


       example# /usr/krb5/bin/ktutil
           ktutil: rkt /etc/krb5/krb5.keytab
           ktutil: list
       slot KVNO Principal
       ---- ---- ---------------------------------------
          1    8 host/vail@ACME.COM
          2    5 host/denver@ACME.COM
           ktutil:delent 2

       slot KVNO Principal
       ---- ---- --------------------------------------

           ktutil:wkt /tmp/krb5.keytab
