Systems and methods for flexible, extensible authentication subsystem that enabled enhance security for applications
The present disclosure is directed towards systems and methods of authenticating a client. A device intermediary to clients servers that provide one or more resources can receive a request from a client to access a resource of the one or more resources. The device can select a login schema associated with the request that includes a definition of a login form. The login schema may correspond to an authentication protocol. The device can generate the login form responsive to the request. The login form can be constructed according to the definition provided by the selected login schema. The device can provide the login form for display via the client. The device can receive information inputted into the login form via the client. The device can establish access to the resource responsive to authentication of the client based on the information and the authentication protocol.
1. A method comprising:
receiving, by a device, a request from a client to access a resource;
selecting, by the device, a login schema from a plurality of login schemas that are used by an authenticator to authenticate the client, the login schema comprising one or more of an authentication schema or a dialog schema that each define a login form using an authentication protocol to communicate with the authenticator;
generating, by a virtual server of the device configured to generate forms based on each of the plurality of login schemas, the login form to authenticate the client using at least the selected login schema;
providing, by the device responsive to the request and for display by a display device of the client, the login form generated by the device based at least on the login schema;
receiving, by the device, information inputted into the login form via the client; and
establishing, by the device responsive to authenticating the client via the authenticator using the authentication protocol and the information, access to the resource by the client.
2. The method of claim 1 , wherein the device is intermediary to the client and the resource.
3. The method of claim 1 , wherein the authenticator is configured on one of a server providing access to the resource or the device.
4. The method of claim 1 , wherein the login schema identifies the dialog schema providing one of a prompt or information via a dialog to facilitate an authentication process via the login form.
5. The method of claim 4 , further comprising generating, by the device, the login form for the client to access the resource based at least on the dialog schema identified by the selected login schema.
6. The method of claim 1 , wherein the login schema identifies the authentication schema providing a definition of one of an authentication page or a login page.
7. The method of claim 6 , further comprising generating, by the device, the login form for the client to access the resource based at least on the authentication schema identified by the selected login schema.
8. The method of claim 1 , further comprising generating, by the device, the login form to be constructed in accordance with the definition of the login schema.
9. The method of claim 1 , wherein the device is configured to interface with the authenticator to authenticate the client.
10. The method of claim 1 , wherein the login schema identifies at least one of a username expression, a password expression or an authentication strength.
11. A system comprising:
a device comprising one or more processors, coupled to memory and configured to:
receive a request from a client to access a resources;
select a login schema from a plurality of login schemas that are used by an authenticator to authenticate the client, wherein the login schema comprises one or more of an authentication schema or a dialog schema that each define a login form using an authentication protocol to communicate with the authenticator;
generate, via a virtual server configured to generate forms based on each of the plurality of login schemas, the login form to authenticate the client using at least the selected login schema;
provide, responsive to the request and for display by a display device of the client, the login form generated by the device based at least on the login schema;
receive information inputted into the login form via the client; and
establish, responsive to authentication of the client via the authenticator using the authentication protocol and the information, access to the resource by the client.
12. The system of claim 11 , wherein the device is intermediary to the client and the resource.
13. The system of claim 11 , wherein the authenticator is configured on one of a server providing access to the resource or the device.
14. The system of claim 11 , wherein the login schema identifies the dialog schema providing one of a prompt or information via a dialog to facilitate an authentication process via the login form.
15. The system of claim 14 , wherein the device is further configured to generate the login form for the client to access the resource based at least on the dialog schema identified by the selected login schema.
16. The system of claim 11 , wherein the login schema identifies the authentication schema providing a definition of one of an authentication page or a login page.
17. The system of claim 11 , wherein the device is further configured to generate the login form for the client to access the resource based at least on the authentication schema identified by the selected login schema.
18. The system of claim 11 , wherein the device is further configured to generate the login form to be constructed in accordance with the definition of the login schema.
19. The system of claim 11 , wherein the device is configured to interface with the authenticator to authenticate the client.
20. The system of claim 11 , wherein the login schema identifies at least one of a username expression, a password expression or an authentication strength.
