[Samba] List Samba 4 shares using server's IP AND Kerberos authentication

[Kristofers]

I am able to list the Samba 4.0.3 shares by using
"*smbclient -L myhostname -k*" command.
However I am unable to do the same by using
"*smbclient -L 192.168.1.2 -k*"
and I get the "session setup failed: NT_STATUS_LOGON_FAILURE" error.

Nevertheless it does work when I try to do the same by using the IP and 
a username like this:
"*smbclient -L 192.168.1.2 -U administrator*".
Is it possible to perform this task using the IP *and* Kerberos 
authentication?
