KVNO(1) 				   MIT Kerberos 				  KVNO(1)

NAME
       kvno - print key version numbers of Kerberos principals

SYNOPSIS
       kvno [-c ccache] [-e etype] [-q] [-h] [-P] [-S sname] [-U for_user] 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  ser-
	      vices  named on the command line.  This is useful in certain backward compatibility
	      situations.

       -q     Suppress printing output when successful.  If a service ticket cannot be	obtained,
	      an error message will still be printed and kvno will exit with nonzero status.

       -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  the  service1 service2 ... arguments are interpreted as hostnames,
	      and the service principals are to be constructed from those hostnames and the  ser-
	      vice  name  sname.   The	service  hostnames will be canonicalized according to the
	      usual rules for constructing service principals.

       -U for_user
	      Specifies that protocol transition (S4U2Self) is to be used to acquire a ticket  on
	      behalf  of  for_user.  If constrained delegation is not requested, the service name
	      must match the credentials cache client principal.

ENVIRONMENT
       kvno uses the following environment variable:

       KRB5CCNAME
	      Location of the credentials (ticket) cache.

FILES
       FILE:/tmp/krb5cc_%{uid}
	      Default location of the credentials cache
