NAME
kvno - print key version numbers of Kerberos principals SYNOPSIS
kvno [-c ccache] [-e etype] [-q] [-h] [-P] [-S sname] [-U foruser] 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 foruser Specifies that protocol transition (S4U2Self) is to be used to acquire a ticket on behalf of foruser. 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
