[Samba] What is a substitute for those parameters in Samba4

[Adnan Kunic]

Dear all,

When I set those parameters in smb.conf

logon path = \\samba.example.com\profiles\%U\%a
logon drive = P:

I receive a following error on Samba4 startup

service samba4 restart
Shutting down Samba services:                              [  OK  ]
Starting Samba services: Unknown parameter encountered: "logon path"
Ignoring unknown parameter "logon path"
Unknown parameter encountered: "logon drive"
Ignoring unknown parameter "logon drive"
                                                           [  OK  ]

Can you help me with this
