KVNO(1)                                                                KVNO(1)

       kvno - print key version numbers of Kerberos principals

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

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

       -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  com-
              mand line.  This is useful 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 speci-
              fied, the service1 service2 ...  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 delegation is not requested, the service name must match  the  credentials  cache  client

       Kvno uses the following environment variable:

       KRB5CCNAME      Location of the credentials (ticket) cache.

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

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