External storage support with windows server 2022 showing not all files / folders

[wolftobias]

Describe the bug

I'm using Ubuntu 22.04 / ownCloud 10.13.4 (stable) in a docker container and mysql 8 in a docker container with enabled external smb storage.
The external storage became green after configuration, but when I login as the user itself in the user space, it shows only the root file share but not all sub files/folders! This happens for some user, but one user has some subfolders but not everthing is showing up.

I tried so far:

• smbclient from inside the owncloud docker container is fine, everything is browseable and like it should be.
• I have updated the docker container with apt-get and tried to update smbclient/php.
• I have disabled all unneeded apps like sharing, federation etc.
• Enabled "Windows Network Drive" Enterprise Feature is working, but it's not desired!!!

My Docker config
docker run --name owncloud --network="intern" --restart=always
-e OWNCLOUD_ADMIN_USERNAME=root
-e OWNCLOUD_ADMIN_PASSWORD=xxx
-e OWNCLOUD_DB_TYPE=mysql
-e OWNCLOUD_DB_NAME=owncloud_db
-e OWNCLOUD_DB_USERNAME=owncloud
-e OWNCLOUD_DB_PASSWORD=xxx
-e OWNCLOUD_DB_HOST=mysql
-e OWNCLOUD_SUB_URL=/owncloud
-e OWNCLOUD_TRUSTED_DOMAINS="xxx"
-d -p 8082:8080 owncloud/server

docker run --name mysql --network="intern" --restart=always -e MYSQL_ROOT_PASSWORD=xxx -v bind-address=0.0.0.0 -d -p 3306:3306 -p 33060:33060 mysql:latest
