A method for providing access control to a single sign-on computer network is disclosed. A user is assigned to multiple groups within a computer network. In response to an access request by the user, the computer network determines a group pass count based on a user profile of the user. The group pass count is a number of groups in which the access request meets all their access requirements. The computer network grants the access request if the group pass count is greater than a predetermined high group pass threshold value.
