Abstract

A framework, which conforms to the OAuth standard, involves a generic OAuth authorization server that can be used by multiple resource servers in order to ensure that access to resources stored on those resource servers is limited to access to which the resource owner consents. Each resource server registers, with the OAuth authorization server, metadata for that resource server, indicating scopes that are recognized by the resource server. The OAuth authorization server refers to this metadata when requesting consent from a resource owner on behalf of a client application, so that the consent will be of an appropriate scope. The OAuth authorization server refers to this metadata when constructing an access token to provide to the client application for use in accessing the resources on the resource server. The OAuth authorization server uses this metadata to map issued access tokens to the scopes to which those access tokens grant access.

First claim

What is claimed is:

1. A method comprising:
receiving, at an authorization computing system, a request to access a resource server from a client application that executes in a context of an identity domain of a plurality of identity domains;
identifying, at the authorization computing system, a service profile that is applicable only to the identity domain of the plurality of identity domains, wherein the service profile includes information identifying a set of resource servers that the client application is permitted to access in the context of the identity domain;
determining, at the authorization computing system and based on the set of resource servers identified by the information in the service profile, whether the client application is permitted to access the resource server in the context of the identity domain, wherein the client application is permitted access to the resource server upon determining that the resource server is included in the set of resource servers;
upon determining that the client application is not permitted to access the resource server in the context of the identity domain, denying, at the authorization computing system, the request to access the resource server, wherein denying the request to access the resource server includes blocking communication from the client application to the resource server in the context of the identity domain; and
upon determining that the client application is permitted to access the resource server in the context of the identity domain, accessing, at the authorization computing system, the resource server to obtain scope information for the resource server; and
generating, at the authorization computing system, based on the scope information obtained from the resource server, a token for the client application to access the resource server.

2. The method of claim 1 , wherein the authorization computing system is included in an OAuth authorization server.

3. The method of claim 1 , further comprising:
receiving, at the authorization computing system, an authentication request to authenticate the client application; and
upon receiving the authentication request, selecting, from a plurality of client plug-ins, a client plug-in that is mapped to the identity domain and sending the authentication request to the client-plug in.

4. The method of claim 1 , further comprising:
identifying based on the request, a service requested by the client application; and
determining, based on the service, the resource server to be accessed by the client application for the service.

5. The method of claim 1 , further comprising:
determining using the service profile, a callback uniform resource locator (URL) corresponding to the resource server, wherein accessing the resource server is performed using the callback URL, and wherein the resource server determines the scope information based on an authorization policy associated with the identity domain.

6. The method of claim 1 , wherein the scope information indicates one or more operations that are permitted for a service accessing a resource provided by the resource server, and wherein the service is indicated in the request.

7. The method of claim 1 , wherein the service profile indicates one or more services that the client application is permitted to access, and wherein the one or more services are provided by the resource server.

8. The method of claim 7 , further comprising:
determining using the service profile, that a service indicated in the request by the client application is not included in the one or more services that the client application is permitted to access; and
denying the request based on determining that the service not included in the one or more services.

9. A computing system comprising:
one or more hardware processors; and
a memory operatively coupled to the one or more hardware processors, the memory storing a set of instructions that, when executed by the one or more hardware processors, causes the one or more hardware processors to:
receive a request to access a resource server from a client application that executes in a context of an identity domain of a plurality of identity domains;
identify a service profile that is applicable only to the identity domain of the plurality of identity domains, wherein the service profile includes information identifying a set of resource servers that the client application is permitted to access in the context of the identity domain;
determine, based on the set of resource servers identified by the information in the service profile, whether the client application is permitted to access the resource server in the context of the identity domain, wherein the client application is permitted access to the resource server upon determining that the resource server is included in the set of resource servers;
upon determining that the client application is not permitted to access the resource server in the context of the identity domain, deny the request to access the resource server, wherein denying the request to access the resource server includes blocking communication from the client application to the resource server in the context of the identity domain; and
upon determining that the client application is permitted to access the resource server in the context of the identity domain, access the resource server to obtain scope information for the resource server; and
generate, based on the scope information obtained from the resource server, a token for the client application to access the resource server.

10. The computing system of claim 9 , wherein the one or more hardware processors and the memory are included in an OAuth authorization server.

11. The computing system of claim 9 , wherein the set of instructions, when executed by the one or more hardware processors, further causes the one or more hardware processors to:
receive an authentication request to authenticate the client application; and
upon receiving the authentication request, select, from a plurality of client plug-ins, a client plug-in that is mapped to the identity domain and send the authentication request to the client-plug in.

12. The computing system of claim 9 , wherein the set of instructions, when executed by the one or more hardware processors, further causes the one or more hardware processors to:
identify, based on the request, a service requested by the client application; and
determine, based on the service, the resource server to be accessed by the client application for the service.

13. The computing system of claim 9 , wherein the set of instructions, when executed by the one or more hardware processors, further causes the one or more hardware processors to:
determine, using the service profile, a callback uniform resource locator (URL) corresponding to the resource server, wherein accessing the resource server is performed using the callback URL, and wherein the resource server determines the scope information based on an authorization policy associated with the identity domain.

14. The computing system of claim 9 , wherein the scope information indicates one or more operations that are permitted for a service accessing a resource provided by the resource server, and wherein the service is indicated in the request.

15. The computing system of claim 9 , wherein the service profile indicates one or more services that the client application is permitted to access, and wherein the one or more services are provided by the resource server.

16. The computing system of claim 15 , wherein the set of instructions, when executed by the
