I did a fresh install OC 9.1.0 (stable) on Ubuntu Linux 16.04.1. this version is installed php 7, so the application user and group LDAP backend does not work, why it needs php5-ldap.
how can I do to fix it to install the ldap configuration?
Thank you very much.
You probably just need to install php7.0-ldap and enable this module.
great! it works!
