I tested with a machine not joined.
I tried to access a shared folder with permissions, but didn’t work.
I gave credential DOMAIN\user and password and suddendly the home directory of this user appeared and I got access to it. But no access to the shared folder I wanted? The user is in acl of the shared folder.
If shared folder has “allow to everyone” access is granted to every machine no matter if joined or not.
I did: net use z: \\xxx.xxx.xxx.xxx\firstname.lastname@example.org /user:DOAMIN\user password and the user home directory was created and access was granted.
@davidep But we know now, that the user home directory is created with first login. I checked before that the home directory didn’t exist.
Why I don’t get access to the shared folder I don’t know.
Will do some tests later.
