    <p>I have a server in python that provides pages. The log-in to these pages is done using an IdP (identity provider). So when the user tries to open my server page, he is redirected to the IdP page. In the meanwhile my server starts listening for the IdP response. When the user logs in the in IdP page, the IdP sends data to my server, that handles them and shows my page to the user.</p> <p>The problem is that if multiple clients try to log in, when the server receives the first response from one IdP, all the users will show my page as logged in with the credential of the first user. </p> <p>I mean, when the server starts listening, it's awaiting for everyone. When just the first user logs in, all the user that are awaiting logs with the same credentials.</p> <p>How can I solve this very big problem? Multithreading may help?</p> <p>Here some of the important code. Let's say that i want to load some of the data answered by the idp, into the fields 'name' of the login-form of my page.</p> <pre><code>class Login(django.forms.SelfHandlingForm): def __init__(self, *args, **kwargs): super(Login, self).__init__(*args, **kwargs) response = self.getIdPResponse() self.fields['name'].widget=forms.TextInput(attrs={'value': response['name']}) def getIdPResponse(self): global response response = None timeout = 300 class RequestHandler(BaseHTTPServer.BaseHTTPRequestHandler): def do_POST(self): global response self.send_response(200) self.send_header("Content-type", "text/html") self.end_headers() varLen = int(self.headers["Content-Length"]) #response = urlparse.parse_qs(self.rfile.read(varLen)) response = self.rfile.read(varLen) self.wfile.write("Log-in ok! now you can close this page.") httpd = BaseHTTPServer.HTTPServer(('0.0.0.0', 8080), RequestHandler) try: httpd.socket.settimeout(1) except BaseException as e: print e count = 0 '''at this point, the IdP page is already showed to the user ''' while response is None and count &lt; timeout: try: httpd.handle_request() count = count + 1 print 'waiting for the Idp answer...' except Exception as e: print e return response </code></pre> <p>in this way, when an user successfully logs-in, all the user that are waiting to login, will show in the field 'name' the name of the user that first logged in. Obviously I don't want this.</p>

    1. COPlease include some code, specifically the parts that are relevant here, how do you validate the clients, and how are you parsing their credentials?

    3. COI'm not sure what Useless knew that I don't when he answered you, but which software provides the server functionality? Is it a Python stand-alone piece of software, or do you have apache/nginx/... set up?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
