Solve the following python programming problem given the following code:
def identify(self, environ) : 
    path_info = environ ['PATH_INFO'] 
    query = parse_dict_querystring (environ) 
    if (path_info == self._logout_url) : 
        environ ['repoze.who.application'] = HTTPUnauthorized () 
        return None 
else : 
        if (path_info == self._login_url) : 
            form = parse_formvars (environ) 
            form.update (query) 
            try : 
                credentials = { 
                    'login' : form ['login'], 
                    'password' : form ['password'], 
} 
except KeyError : 
                credentials = None 
def auth_resp(environ, start_response) : 
                import json 
                resp = { 
                    'success' : True, 
} 
                resp_str = json.dumps (resp) 
                content_length = CONTENT_LENGTH.tuples (str (len (resp_str))) 
                content_type = CONTENT_TYPE.tuples ('application/json') 
                headers = (content_length + content_type) 
                start_response ('200 OK', headers) 
                return [resp_str] 
environ ['repoze.who.application'] = credentials 
            return credentials 

    
    

    Fix the buggy line: environ ['repoze.who.application'] = credentials
