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  services  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 service 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
