Abstract

System for authenticating a user for logon to a content manager running on top of a database manager. A connect procedure connects the user to a database manager; and then a logon procedure logs on the user to the content manager selectively responsive to the user connecting to the database manager; the user being authenticated by a third party by way of a user exit or a trusted logon environment and privilege; or the user being authenticated by the content manager.

Claims

1. A method for authenticating a user for access to controlled entities maintained at a server, said server including a content manager, a database manager, an user application, and user exits, comprising:

maintaining said controlled entities within said content manager, said controlled entities including an access control list table bound to user data items, said access control list table including in rows for each user and user group user kind, user identifier, access control list code, and privilege set code, each privilege set code corresponding to a privilege set;

said maintaining, responsive to modification of a given privilege set, including incrementally refreshing said access control list table to refresh only those rows having a privilege set code corresponding to said given privilege set;

connecting said user to a said database manager; and

logging on said user to said content manager running on top of said database manager to enable access by said user to said user data items selectively responsive to said user connecting to said database manager;

said user being authenticated by a third party; and

said user being authenticated with reference to said access control list table by said content manager; and

said user being logged on to said content manager responsive to said user connecting to said database manager when database (DB) user indicia and content manager (CM) user indicia are the same.

2. The method of claim 1, said user being logged on to said content manager by content manager authentication responsive to said content manager receiving database (DB) user indicia for a DB user having connect privilege and a correct logon password.

3. The method of claim 1, said user being logged on to said content manager by third party authentication responsive to a user exit authenticating content manager (CM) user indicia.

4. The method of claim 1, said user being logged on to said content manager by third party authentication responsive to said content manager receiving database (DB) user indicia for a DB user having connect and trusted logon privileges in a trusted logon system environment.

5. A method for authenticating a user for access to controlled entities maintained at a server, said server including a content manager, a database manager, an user application, and user exits, comprising

maintaining controlled entities within said content manager, said controlled entities within said content manager, said controlled entities including an access control list table bound to user data items, said access control list table including in rows for each user and user group content manager user indicia, access control list code, and privilege set code, each privilege set code corresponding to a privilege set;
