NAME
       kvno - print key version numbers of Kerberos principals

SYNOPSIS
       kvno [-q] [-h] [-c ccache] [-e etype] service1 service2 ...

DESCRIPTION
       Kvno  acquires  a  service ticket for the specified Kerberos principals
       and prints out the key version numbers of each.

OPTIONS
       -c ccache
	      specifies the name of a credentials cache to  use	 (if  not  the
	      default)

       -e etype
	      specifies	 the  enctype  which will be requested for the session
	      key of all the services named on the command line.  This is use‐
	      ful in certain backward compatibility situations.

       -q     suppress printing

       -h     prints a usage statement and exits

       -P     specifies	 that  the  service1 service2 ...  arguments are to be
	      treated as services for which  credentials  should  be  acquired
	      using  constrained  delegation.  This  option is only valid when
	      used in conjunction with protocol transition.

       -S sname
	      specifies that krb5_sname_to_principal() will be used  to	 build
	      principal	 names.	  If this flag is specified, the service1 ser‐
	      vice2 ...	 arguments are interpreted as hostnames	 (rather  than
	      principal names), and sname is interpreted as the service name.

       -U for_user
	      specifies	 that  protocol transition (S4U2Self) is to be used to
	      acquire a ticket on behalf of for_user.  If constrained  delega‐
	      tion  is	not requested, the service name must match the creden‐
	      tials cache client principal.

ENVIRONMENT
       Kvno uses the following environment variable:

       KRB5CCNAME      Location of the credentials (ticket) cache.

FILES
       /tmp/krb5cc_[uid]  default location of the credentials cache ([uid]  is
			  the decimal UID of the user).

SEE ALSO
       kinit(1), kdestroy(1), krb5(3)
