Hi To-M,

Authentification method :
- Windows : net use Y: \\10.1.1.15\prod-share /user:user pwd /PERSISTENT:YES
- Mac: smb://user@10.1.1.15/prod-share
And yes, before it worked correctly. But we had problem with AFP on MAC and we used SMB...
I will proceed to create new share and test with Windows/MAC users.

Best regards,
Charlie.
