Proxysql configures the ldap plugin:
ldap_auth_plugin=“/path/to/MySQL_LDAP_Authentication_plugin.so”
Where does the MySQL_LDAP_Authentication_plugin.so come from?
Does it need to be compiled in before use it?

The ProxySQL LDAP plugin is a ProxySQL enterprise or paid offering only. Contact ProxySQL for more information Support - ProxySQL
