/**
* Retrieves the Zikula User ID (uid) for the given authenticationInfo, from the mapping maintained by this authenticationModule.
*
* Custom authenticationModules should pay extra special attention to the accurate association of authenticationInfo and user
* ids (uids). Returning the wrong uid for a given authenticationInfo will potentially expose a user's account to
* unauthorized access. Custom authenticationModules must also ensure that they keep their mapping table in sync with
* the user's account.
*
* Note: (Specific to Zikula Users module authentication) This function uses mb_strtolower, and assumes that
* locale == charset.
*
* Parameters passed in $args:
* ---------------------------
* array $args['authentication_info'] The information needed for this authenticationModule, including any user-entered
* information. For the Users module, this contains the elements 'login_id' and 'pass'.
* The 'login_id' element contains either the user name or the e-mail address of the
* user logging in, depending on the authentication_method. The 'pass' contains the
* password entered by the user.
* array $args['authentication_method'] An array containing the authentication method, including the 'modname' (which should match this
* module's module name), and the 'method' method name. For the Users module, 'modname' would
* be 'Users' and 'method' would contain either 'email' or 'uname'.
*
* @param array $args All arguments passed to this function.
* array authenticationInfo The authentication information uniquely associated with a user.
*
* @return integer|boolean The integer Zikula uid uniquely associated with the given authenticationInfo;
* otherwise false if user not found or error.
*
* @throws Zikula_Exception_Fatal Thrown if invalid parameters are sent in $args.
