I have the same problem.
Cannot continue with LDAP.
The App is un-responsive.

Debian 10
Nextcloud 20
nginx
php7.4

Thanks

Same problem on my server since the upgrade from 19.0.4 to 20.0.1.

Debian (stable, buster)
PHP 7.3
Nginx 1.14.2
MariaDB 10.3.5
slapd 2.4.47

Update: it seems like the latest Nginx configuration for Nextcloud might be the culprit of this error, as it's working with the one recommended for NC19.

I changed my nginx config to the recommended for NC19 - LDAP now works - Thanks @gllmhyt
