    test_smb: test S4U2Self operation by IPA service
    
    Kerberos service might request a ticket to itself on behalf of a user
    to perform protocol transition, so-called S4U2Self extension defined
    in [MS-SFU] specification. Processing of this request by KDC differs for
    in-realm and cross-realm configurations.
    
    Use SMB service to test S4U2Self performed against AD and IPA users.
