@girish Thank you!
@girish good job. it works 👍
The package was initially made by @jimcavoli . It seems he initially packaged with LDAP but subsequently removed it - https://git.cloudron.io/cloudron/grav-app/-/commit/94f656384e6c808e5a2bbc59e944f587f5362382 . @jimcavoli do you remember why?
Oh yes, i just realized that it actually is already setup. Sorry - works fine 🙂
In my case I was installing the plugin via the webinterface.
To reset the permissions usually in all apps an app restart does this already. So maybe indeed a simply app restart fixes that.
