Under the authentication section in this link, it is given for Anonymous search and bind: simply set authenticatedBind to false. Could you please tell me how should I do that?
@esyana In GForge 6.3.x and earlier, each of the modules (plugins) in GForge has its own configuration file. They're all located in /etc/gforge, with the core settings in gforge.conf and plugin-specific settings in the appropriate folder under plugins/. You'll find the setting ldap.authenticatedBind in /etc/gforge/plugins/ldap/ldap.conf
If you update the value there, then run cd /opt/gforge/bin && php create_config_cache.php to make the change take effect.
In GForge 6.4 and newer, all settings are stored in the database and accessible using a shell script. Run /opt/gforge/bin/gf-config set "ldap.authenticatedBind" false to make the change. It takes effect immediately.
