add new configuration item skipBindError to skip bind error

+         if(Meteor.settings.ldap.skipBindError) {
 +            console.log('A bind error occured and skipped due to configuration skipBindError : true');
 +            return;
 +        } else {
 +            throw new Error("Unable to bind to LDAP");
 +        }
