Summary of the issue you are facing:
When I try to connect to my AD server using the LDAP/AD integration, Nextcloud is unable to establish a connection. When I check my log files, I see this PHP error:
ldap_search(): Search: Operations error at /snap/nextcloud/46970/htdocs/apps/user_ldap/lib/LDAP.php#282
Steps to replicate it (hint: details matter!):
- Set up a Windows server as an Active Directory domain controller (or use an existing domain)
- Enable the LDAP user and group backend
- Go to Administrative Settings > LDAP/AD integration
- Enter the details for your AD domain (hostname/IP and port for your domain controller, user DN, password, base DN)
- Click “Test Base DN”
