Accessing an application through application clients and web browsers

1. A method comprising:

deploying an authorization server to control access of one or more application clients to a plurality of protected applications;

receiving, at a protected application of the plurality of protected applications, a request comprising an access token from an application client of the one or more application clients which is associated with a user, wherein the access token is issued by the authorization server during authorization of the application client for accessing the protected application;

upon determining that the access token is valid at the protected application, retrieving, from the authorization server, grant information comprising intersecting scopes of rights between Open Authorization (OAuth) rights requested to be granted to the application client at the authorization server, rights mapped to a Java role of the user at the authorization server, and rights mapped to the protected application, wherein the intersecting scopes of rights comprises an overlap between corresponding scopes of the rights of the OAuth rights requested to the granted, the rights mapped to the Java role of the user, and the rights mapped to the protected application; and

establishing a direct session between the application client and the protected application based on the intersecting scopes of rights.

2. The method of claim 1 , further comprising processing a request based on at least one scope of rights delegated to the application client that is mapped to at least one API provided by the protected application and accessible by the application client.

3. The method of claim 1 , wherein establishing the session with the application client further comprises:

marking the established session with a session author marker to specify the session is based on the intersecting scopes of rights.

4. The method of claim 3 further comprises:

disconnecting the application client from the protected application; and

invalidating the established session to reduce a number of established sessions in the protected application upon determining that the established session is marked.

5. The method of claim 1 further comprises:

determining the intersecting scopes of rights by further intersecting the intersecting scopes of rights with a third set of scopes of rights mapped to the protected application.

6. The method of claim 5 further comprises:

sending a request to the user to approve the determined plurality of intersecting scopes of rights; and

upon approval, adding the plurality of intersecting scopes of rights to the grant information.

7. The method of claim 5 further comprises:

sending the access token for authentication with the protected application to the application client; and

associating the access token with the grant information.

8. A non-transitory computer readable medium storing instructions, which when executed by at least one processor cause a computer to:

deploy an authorization server to control access of one or more application clients to a plurality of protected applications;

receive, at a protected application of the plurality of protected applications, a request comprising an access token from an application client of the one or more application clients which is associated with a user, wherein the access token is issued by the authorization server during authorization of the application client for accessing the protected application;

upon determining that the access token is valid at the protected application, retrieve, from the authorization server, grant information comprising intersecting scopes of rights between Open Authorization (OAuth) rights requested to be granted to the application client at the authorization server, rights mapped to a Java role of the user at the authorization server, and rights mapped to the protected application, wherein the intersecting scopes of rights comprises an overlap between corresponding scopes of the rights of the OAuth rights requested to the granted, the rights mapped to the Java role of the user, and the rights mapped to the protected application; and

establish a direct session between the application client and the protected application based on the intersecting scopes of rights.

9. The computer readable medium of claim 8 , wherein the executed instructions further cause the computer to:

mark the established session with a session author marker to specify the session is based on the intersecting scopes of rights;

disconnect the application client from the protected application; and

invalidate the established session to reduce a number of established sessions in the protected application upon determining that the established session is marked.

10. The computer readable medium of claim 8 , wherein the executed instructions further cause the computer to:

determine the intersecting scopes of rights by further intersecting the intersecting scopes of rights and a third set of scopes of rights mapped to the protected application.

11. The computer readable medium of claim 10 , wherein the executed instructions further cause the computer to:

send a request to the user to approve the intersecting scopes of rights;

upon approval, add the plurality of intersecting scopes of rights to the grant information;

send the access token for authentication with the protected application to the application client; and

associate the access token with the grant information.

12. The method of claim 1 , wherein the establishing comprises establishing a communication session between the application client and the protected application based on OAuth protocol.

13. A computing system comprising:

a hardware processor configured to deploy an authorization server to control access of one or more application clients to a plurality of protected applications; and

a network communicator configured to receive, via a protected application of the plurality of protected applications, a request comprising an access token from an application client of the one or more application clients which is associated with a Java user, wherein the access token is issued by the authorization server during authorization of the application client for accessing the protected application,

wherein the hardware processor is further configured to retrieve grant information comprising intersecting scopes of rights between Open Authorization (OAuth) rights requested to be granted to the application client at the authorization server, and rights mapped to a Java role of the Java user at the authorization server, and rights mapped to the protected application, wherein the intersecting scopes of rights comprises an overlap between corresponding scopes of the rights of the OAuth rights requested to the granted, the rights mapped to the Java role of the user, and the rights mapped to the protected application, and

establish a direct session between the application client and the protected application based on the intersecting scopes of rights.

14. The computing system of claim 13 , wherein the hardware processor is further configured to process a request based on at least one scope of rights delegated to the application client that is mapped to at least one API provided by the protection protected application and accessible by the application client.

15. The computing system of claim 13 , wherein the hardware processor is further configured to mark the established session with a session author marker to specify the session is based on the plurality of intersecting scopes of rights.

16. The computing system of claim 15 , wherein the hardware processor is further configured to disconnect the application client from the protected application, and invalidate the established session to reduce a number of established sessions in the protected application upon determining that the established session is marked.

17. The computing system of claim 13 , wherein the hardware processor is further configured to control the network communicator to transmit a request to the user to approve the determined plurality of intersecting scopes of rights, and upon approval, add the plurality of intersecting scopes of rights to the grant information.

18. The computing system of claim 13 , wherein the hardware processor is configured to establish a communication session between the application client and the protected application based on OAuth protocol.
