Embodiments of the invention generally provide methods, systems, and articles of manufacture that facilitate classification of a data access authority of unclassified users into one or more categories, and control access of data by the users based on the categories. When an unclassified user is found in an organization chart, one or more classified users near the unclassified user in the data tree may be identified. The unclassified user may be compared to the identified classified users to determine one or more suggested data access categories for classifying the unclassified user. The unclassified user may therefore be classified into one of the suggested data access category based on, for example, user input.
