samba - Oct 2016 - Query Regarding local user authentication for ftp not working

Hi Team,

Upgraded samba from 4.3.11 to 4.5.0,

Ftp using pam_smbpass.so for local user authentication. Due to removal
pam_smbpass i have changed it to pam_winbind.so

Is there any additional settings or config change needed to  make ftp local
user authentication  work

i have added user through smbpasswd. cifs is working fine with that user
but ftp authentication fails.

Help me to sort out the issue. where i missed.

Regards,
