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
