Using docker and ldap. occ maintenance:repair didn't help.
Also this guy seems to have the same issue: https://help.nextcloud.com/t/no-create-permission-for-path/39517

Looks like a caching problem?

Probably related to #10436. Fixed it by removing the whole data/appdata_* folder and following the steps mentioned here: https://github.com/nextcloud/server/issues/10436#issuecomment-408896858

I solved a similar problem by commenting out that access check. Nextcloud has the correct permissions. The checkPermissions method is broken, or rather whatever that thing calls.
