Sure, i have a suggestion. 

security = user ? In samba 4.9.x ?  And using domain logings?? 

Run man smb.conf
Search : security = 


Then goto : map to guest (G) 
Read that. 

Then goto : security (G) 
And read that also. 

I think you didnt read the complete changelog between 4.5.x and 4.9.x also ;-)

>> To be able to loing, I've to select Other User, enter username and

If you do that, your typing DOM\username ? Or only "username"  

Because, all windows logings now using COMPUTERNAME\username localy. 
So if you enter "username" for the PDC login it passes " COMPUTERNAME\username" to samba most probely.

I hope above helps you a bit, but as far i can see above is only a configuration issue. 
You need to review the config and setup for security=domain.
