Error in custom soap api call in magento

Question

I am developing a custom api using soap call in magento to login customer from mobile app to magento and then redirect back to mobile app.I have created the customer using the default soap calls in magento but there is no soap function for login the customers.i have created the custome api similar to the default customer creation method but am getting the below error.

[faultstring] => Function ("customerCustomerUserlogin") is not a valid method for this service [faultcode] => Client [faultcodens] => http://schemas.xmlsoap.org/soap/envelope/

The code below is am using

$soapclient = new SoapClient('http://localhost/magento/api/v2_soap/?wsdl');
            //$soapclient = new SoapClient('http://localhost/magento/api/soap/?wsdl',$opt);

            $session = $soapclient->login('soapapi','devmage123');

            $customerId = $soapclient->customerCustomerUserlogin($session, $loginDetails);

Here is the code i have used :

in customer/etc/api.xml

<config>
    <api>
        <resources>
            <customer translate="title" module="customer">

After in api.xml try adding the following:

   <v2>
        <resources_function_prefix>
            <customerCustomer>customerCustomer</customerCustomer>
        </resources_function_prefix>
    </v2>
