       kinit - Kerberos login utility

       kinit [ -irvl ]

       The  kinit  command is used to login to the Kerberos authentication and
       authorization system.  Note that only registered Kerberos users can use
       the  Kerberos  system.  For information about registering as a Kerberos
       user, see the kerberos(1) manual page.

       If you are logged in to a workstation that is running the toehold  ser‐
       vice,  you  do not have to use kinit.  The toehold login procedure will
       log you into Kerberos automatically.  You will need to use  kinit  only
       in  those  situations  in  which	 your  original	 tickets have expired.
       (Tickets expire in about a day.)	 Note as well that toehold will	 auto‐
       matically destroy your tickets when you logout from the workstation.

       When  you use kinit without options, the utility prompts for your user‐
       name and Kerberos password, and tries to authenticate your  login  with
       the local Kerberos server.

       If  Kerberos authenticates the login attempt, kinit retrieves your ini‐
       tial ticket and puts it in the ticket file specified by your  KRBTKFILE
       environment  variable.  If this variable is undefined, your ticket will
       be stored in the /tmp directory, in the file tktuid , where uid	speci‐
       fies your user identification number.

       If  you	have logged in to Kerberos without the benefit of the worksta‐
       tion toehold system, make sure you use the kdestroy command to  destroy
       any  active tickets before you end your login session.  You may want to
       put the kdestroy command in your .logout file so that your tickets will
       be destroyed automatically when you logout.

       The options to kinit are as follows:

       -i     kinit prompts you for a Kerberos instance.

       -r     kinit  prompts  you  for a Kerberos realm.  This option lets you
	      authenticate yourself with a remote Kerberos server.

       -v     Verbose mode.  kinit prints the name of the  ticket  file	 used,
	      and  a  status message indicating the success or failure of your
	      login attempt.

       -l     kinit prompts you for a ticket lifetime in minutes.  Due to pro‐
	      tocol  restrictions  in  Kerberos	 Version 4, this value must be
	      between 5 and 1275 minutes.

       The -r option has not been fully implemented.
