ZF-12132: Zend_Auth_Adapter_Http basic authentication bug
Zend_Auth_Adapter_Http checks for fix ZF-1515 (line 534) that credentials should be:
$creds = array_filter(explode(':', $auth));
$password = $this->_basicResolver->resolve($creds, $this->_realm);
In Zend_Auth_Adapter_Http_Resolver_File (lines 154 to 162) the file is read splitted by colons. It understans that: $line == $username && $line == $realm && $password = $line but that's not right. The realm is being passed as parameter and the Zend_Auth_Adapter_Http forces that a two parameters file should be used.
