While investigating Issue #5 I encountered the following error message when attempting to run 1000 consecutive user lookups:

```
PHP Fatal error: SOAP-ERROR: Parsing WSDL: Couldn't load from 'https:///d2l/AuthenticationTokenService.asmx?WSDL' : failed to load external entity "https:///d2l/AuthenticationTokenService.asmx?WSDL"
in /Zend/Soap/Client/Common.php on line 51
```

This is puzzling as it always happens at the 512th consecutive request. Appears to be some sort of internal throttling mechanism within Desire2Learn Web Services
