Nextcloud fpm docker image with ldap support

The nextcloud fpm docker image is not working with ldap support (users etc.) - cannot add server etc. Is this a bug or a configuration error? I cannot find any related documentation. Tried the LDAP support with nginx reverse proxy to nextcloud:apache - working normally, so there must be some incompatibility with FPM protocol. Any suggestions? Thanks. Maros V.
