We don't use Red Hat Linux but CentOS. I have OwnCloud, Tiki, some build servers (TeamCity) and I'm will build some kind of internal service for tracking licences we gave to our programmers. Most of the technology is open source so I don't to buy any kind of licence if I can use Kerberos/LDAP/Samba to get what I need.
I just don't understand how I can forward credentials to other services.

KVNO(1) General Commands Manual KVNO(1)
NAME
kvno - print key version numbers of Kerberos principals
SYNOPSIS
kvno [-q] [-h] [-c ccache] [-e etype] 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 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 specified, 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 principal.
ENVIRONMENT
Kvno uses the following environment variable:
KRB5CCNAME Location of the credentials (ticket) cache.
FILES
/tmp/krb5cc_[uid] default location of the credentials cache ([uid] is the decimal UID of the user).
SEE ALSO
kinit(1), kdestroy(1), krb5(3)
