Issue to map shared folder using AD user -> Access Denied

[bicho doido]

Hello,

I was able to join my two DCs and add privilieges to AD users but everytime I want to connect I get acces denied.

I am able to map a shared folder with a local user, but I cannot authenticate with AD as I always get access is denied.

Do you have any clue how I can troubleshoot this issue ?

Thanks

Had this and I don't know what's wrong. On some computers was no problem to map folder. On others I had 'incorect password or no permission'. So I decided to use qnapfinder and in worked. Next day I had two more laptops and I started with qfinder... no luck at start. I changed SMB from 3 to max 2.1 and after that shared folder mapped. Other users had problems to open shares after nigth. Definitely it doesnt work right.
