	//      user requesting to log in.
	//   3. Lounge tries to connect a second time, but this time using the user's
	//      DN and password. Auth is validated iff this connection is successful.
	//
	// The search query takes a couple of parameters in `searchDN`:
	//   - a base DN `searchDN/base`. Only children nodes of this DN will be likely
	//     to be returned;
	//   - a search scope `searchDN/scope` (see LDAP documentation);
	//   - the query itself, build as (&(<primaryKey>=<username>) <filter>)
	//     where <username> is the user name provided in the log in request,
	//     <primaryKey> is provided by the config and <fitler> is a filtering complement
	//     also given in the config, to filter for instance only for nodes of type
	//     inetOrgPerson, or whatever LDAP search allows.
	//
	// Alternatively, you can specify the `bindDN` parameter. This will make the lounge
	// ignore searchDN options and assume that the user DN is always:
	//     <bindDN>,<primaryKey>=<username>
	// where <username> is the user name provided in the log in request, and <bindDN>
	// and <primaryKey> are provided by the config.
