[Samba] Weird access problem to files

We've recently upgraded a S3 to Samba4 with AD (4.3.11-Ubuntu).
The access control on the old installation was done with "valid users" and "write list". We've ported this to ACL, but for some path users are denied access and we cannot understand why.
I.e. for a generic share, user "user1" can browse and access almost everything except for directory "NONWORKING". So, by doing several test, we found out that copying the very same directory from another user which has access (a domain admin) to a new one, this directory IS accessible by "user1"!
This directory has a specific security entry which allows writing to "user1".
This is a diff of getfacl on the working and nonworking dir.
>From my understanding there's nothing in the first dir ACL which forbids "user1" from accessing NONWORKING directory. Have I missed something? Is there anything else I can check?
