Abstract

A method for allowing anonymous user login to a computer begins when an application request is received from a client. The next available anonymous user name is determined and assigned to the client'"'"'s application request. The anonymous user name is authenticated and a new session is created, which invokes the application targeted by the client'"'"'s application request. When the client terminates execution of the application, the anonymous user name is returned to the anonymous user name pool and is available to be reassigned to the next anonymous user.

Claims

1. A method for providing simultaneous anonymous user login to multiple users of a computer system, each user associated with at least one client node the method comprising the steps of:

(a) receiving an application request from a client node;

(b) selecting a unique user name from a plurality of temporary user names;

(c) associating said unique user name with the application request; and

(d) authenticating the unique user name associated with the application request without knowledge of the identity of the client node making the application request.

2. The method of claim 1 wherein step (b) further comprises:

(b) selecting a unique user name from a linked list of temporary user names.

3. The method of claim 1 wherein step (b) further comprises:

(b) selecting a unique user name from a multi-string of temporary user names.

4. The method of claim 1 wherein step (b) further comprises selecting a unique user name from a plurality of temporary user names, wherein a password is associated with the unique user name selected.

5. The method of claim 1 further comprising the steps of:

(e) creating a new session for the client node; and

(f) invoking an application in response to the application request.

6. The method of claim 5 further comprising the steps of:

(g) receiving a termination signal from the client node; and

(h) disassociating said unique user name from the application request.

7. The method of claim 1, further comprising the step of

(e) removing the temporary user name from the list while the name is in use by the application request.

8. The method of claim 6 further comprising the step of

(c) returning the user name to the list of temporary user names.

9. An apparatus for providing simultaneous anonymous user login to multiple users of a computer system, each user associated with at least one client node, the apparatus comprising:

a plurality of temporary user names stored in a memory element, and

assigning means for assigning at least one of said plurality of temporary user names to an application request made by a client node; and

authenticating means for authenticating the user name assigned to the application request without knowledge of the identity of the client node making the application request.

10. The apparatus of claim 9 further comprising means for receiving an application request from a client node.

11. The apparatus of claim 9 further comprising means for selecting a temporary user name from said plurality of temporary user names.

12. The apparatus of claim 9 wherein said plurality of temporary user names comprises a linked list.

13. The apparatus of claim 9 wherein said linked list is circular.

14. The apparatus of claim 9 wherein said plurality of temporary user names comprises a multi-string.

15. An article of manufacture having computer-readable program means embodied thereon for providing simultaneous anonymous user login to multiple users of a computer system, each user associated with at least one client node, the article comprising:

computer-readable program means for selecting a unique user name from a plurality of temporary user names without knowledge of the identity of the user associated with the client node making the application request; and

computer-readable program means for associating said unique user name with an application request made by a client; and

computer-readable program means for authenticating the user name associated with the application request without knowledge of the identity of the client node making the application request.

16. The article of manufacture of claim 15 further comprising computer-readable program means for receiving an application request from a client node.

17. The article of manufacture of claim 15 further comprising:

computer-readable program means for creating a new session for the client node; and

computer-readable program means for invoking an application in response to the received application request.

18. The article of manufacture of claim 15 further comprising:

computer-readable code means for receiving a termination signal from the client node; and

computer-readable code means for disassociating said unique user name from the application request.

19. A method for providing simultaneous anonymous user login to multiple users of a computer system, each user associated with at least one client node, the method comprising the steps of:

(a) receiving an application request from a client node;

(b) selecting a unique user name from a plurality of temporary user names;

(c) associating said unique user name with the application request;

(d) authenticating the unique user name associated with the application request without knowledge of the identity of the client node making the application request; and

(e) initializing an execution environment for the application request.

20. The method of claim 19, further comprising the step of (f) returning output of the application request to the client node.

21. The method of claim 19, wherein step (e) comprises initializing a security context for the application request.

22. The method of claim 19 wherein step (e) comprises loading a user profile comprising default settings associated with the user name.

23. The method of claim 19 wherein step (e) comprises connecting to default file and print servers.

24. The method of claim 19 wherein step (e) comprises initializing default disk drive mapping and printer connections.

25. The method of claim 19 wherein step (e) comprises loading the execution environments for the requested application.

26. The method of claim 19 wherein step (e) comprises invoking the application identified by the request.
