When a user points a browser to a WebUser port of the CommuniGate Pro server, the Login page is displayed. The WebUser ports are specified in the HTTP User module settings, the default clear-text WebUser port is 8100, the secure one (not configured by default on some platforms) is 9100.
When the Login page is displayed, users can enter their name and password, and start a WebUser Session.
The WebUser module checks for the domain name specified in the URL and presents the Login page for the addressed Domain. If the CommuniGate Pro server provider.com has a secondary Domain client.com, then the http://provider.com:port URL will display the provider.com Login page in a user browser, and the http://client.com:port URL will display the client.com Login page, even if the client.com has no dedicated IP address.
When the WebUser module retrieves the domain name from a URL, it runs it through the Router domain-level records. If the Router Table has a record:
www.client.com = client.com
the http://www.client.com:port URL will be processed as the http://client.com:port URL and it will retrieve the client.com Login page, too. If the URL specifies a domain name that is not routed to any CommuniGate Pro Domains, an error page is displayed. This usually indicates an error in your Server setup: the specified domain name has a DNS A-record that points to your Server (otherwise the Server would not get this request), but that name is not routed to any of the Server Domains. You should either create a secondary Domain with that name, or route this domain name to one of the existing CommuniGate Pro Domain.
If a URL specifies an IP address instead of a domain name, the WebUser module tries to find a CommuniGate Pro Domain to which the specified address is dedicated. If no Domain is found, the Main Domain Login page is displayed.
Users can open any Account in any Domain from any Login page, if they specify the complete Account name: if the Login page of the Main Domain is displayed (http://provider.com:port) and the email@example.com name is entered in the username field, the Account username will be opened in the client.com Domain (if the correct password is provided).
If a Domain has some mailing lists, its Login page contain a link to the Mailing List archive pages.
If the Domain has the Auto-Signup option enabled, a link to the Auto Sign-up page is displayed on the Domain Login page.
If the Domain has a custom Security Certificate, a Certificate link is displayed. If a user clicks that link, the Domain Certificate can be installed as a trusted Certificate in the user browser.
