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?

[michidk]

Probably related to #10436. Fixed it by removing the whole data/appdata_* folder and following the steps mentioned here: #10436 (comment)

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.

As I cannot reproduce the original issue anymore, I will close this ticket. If this is still happening please make sure to upgrade to the latest version. After that, feel free to reopen.
