If you have access to your command line run e.g.:
sudo -u www-data php occ app:list
from within your ownCloud installation folder.
Are you using external storage, if yes which one: yes i use qnap storage and started stftp and tested it’ no ploblem
Are you using encryption: No
Are you using an external user-backend, if yes which one: No
With access to your command line run e.g.:
sudo -u www-data php occ ldap:show-config
from within your ownCloud installation folder
Without access to your command line download the data/owncloud.db to your local
computer or access your SQL server remotely and run the select query:
SELECT * FROM `oc_appconfig` WHERE `appid` = 'user_ldap';
Eventually replace sensitive data as the name/IP-address of your LDAP server or groups.
