Alexander Bokovoy 23a49538f1 ipa-print-pac: acquire and print PAC record for a user
Helper utility to investigate PAC content of users in trusted
environments. Supports direct ticket acquisition and S4U2Self protocol
transition.

1. Direct ticket acquisition

In direct ticket acquisition mode the utility first does one of the
following actions:
 - obtain a TGT ticket for a user principal using supplied password
 - import existing TGT from a default credentials cache

Once a user TGT is available, the utility will attempt to acquire a service
ticket to a service which key is specified in a keytab (default or
passed with --keytab option) and simulate establishing context to the
service application.

If establishing context succeeds, MS-PAC content of the service ticket
will be printed out.

2. S4U2Self protocol transition

In protocol transition case a service application obtains own TGT using
a key from the keytab and then requests a service ticket to itself in
the name of the user principal, performing S4U2Self request.

If accepting this service ticket succeeds, MS-PAC content of the service
ticket will be printed out.

If KDC does not support or rejects issuing MS-PAC record for a user, an
error message 'KDC has no support for padata type' will be printed.
