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 use-
ful 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 inter-
preted as hostnames, and the service principals are to be con-
structed 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 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
FILE:/tmp/volatile-user/%{uid}/krb5cc_%{uid}
Default location of the credentials cache
