kvno - print key version numbers of Kerberos principals
kvno [-c ccache] [-e etype] [-q]
[-h] [-P] [-S sname] [-I for_user]
[-U for_user] [-F cert_file] [--u2u
ccache] service1 service2 ...
kvno acquires a service ticket for the specified Kerberos principals and prints
out the key version numbers of each.
- -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
- Suppress printing output when successful. If a service ticket cannot be
obtained, an error message will still be printed and kvno will exit with
- Prints a usage statement and exits.
- 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
- -I 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
- -U for_user
- Same as -I, but treats for_user as an enterprise name.
- -F cert_file
- Specifies that protocol transition is to be used, identifying the client
principal with the X.509 certificate in cert_file. The certificate
file must be in PEM format.
- --u2u ccache
- Requests a user-to-user ticket. ccache must contain a local krbtgt
ticket for the server principal. The reported version number will
typically be 0, as the resulting ticket is not encrypted in the server's
