[Samba] problem with samba 4 as file-server

[Stéphane PURNELLE]

Hi,

My configuration: 

1 server with Samba4 as a DC (dc01)
1 server with Samba4 as a file/print server

DC seems to work fine.

file server is connected to DC using this howto 
https://wiki.samba.org/index.php/Samba/Domain_Member

smbd, nmbd, winbindd is running on file/print server.

Bu when I try with a windows client (a windows 2003 server) to connect to 
file server.
client ask for a user and password and password not work.

In log file, I can see :
