ABSTRACT:
A login shell and file/directory access checking supporting multiple user credentials are provided. The login shell receives user input from a particular user including login information for a plurality of user accounts for that particular user. The login shell authenticates the plurality of user accounts using the login information and retrieves a plurality of user credentials corresponding to the plurality of user accounts. This plurality of user credentials forms a multi-user credential. In response to a request for access to a file, the access rights to the file for the user are verified by verifying the access rights of the multi-user credential.
