7

SYNOPSIS

9       kvno [-q] [-h] [-c ccache] [-e etype] service1 service2 ...
10

DESCRIPTION

12       Kvno  acquires  a  service ticket for the specified Kerberos principals
13       and prints out the key version numbers of each.
14

OPTIONS

16       -c ccache
17              specifies the name of a credentials cache to  use  (if  not  the
18              default)
19
20       -e etype
21              specifies  the  enctype  which will be requested for the session
22              key of all the services named on the command line.  This is use‐
23              ful in certain backward compatibility situations.
24
25       -q     suppress printing
26
27       -h     prints a usage statement and exits
28
29       -P     specifies  that  the  service1 service2 ...  arguments are to be
30              treated as services for which  credentials  should  be  acquired
31              using  constrained  delegation.  This  option is only valid when
32              used in conjunction with protocol transition.
33
34       -S sname
35              specifies that krb5_sname_to_principal() will be used  to  build
36              principal  names.   If this flag is specified, the service1 ser‐
37              vice2 ...  arguments are interpreted as hostnames  (rather  than
38              principal names), and sname is interpreted as the service name.
39
40       -U for_user
41              specifies  that  protocol transition (S4U2Self) is to be used to
42              acquire a ticket on behalf of for_user.  If constrained  delega‐
43              tion  is  not requested, the service name must match the creden‐
44              tials cache client principal.
45

ENVIRONMENT

47       Kvno uses the following environment variable:
48
49       KRB5CCNAME      Location of the credentials (ticket) cache.
50

FILES

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