Techniques are disclosed for identifying roles with similar membership and/or entitlement information in an identity management system of an enterprise. A role defined in an identity management system may be associated with membership information and entitlement information. The membership information may identify one or more members who has been assigned the role. The entitlement information may determine how members of the role can interact with a target system within the enterprise. The entitlement information may include a list of actions that members of the role can perform on the target system. Embodiments allow for identifying roles that have similar membership and/or entitlement information. If an existing role already gives similar entitlement(s) to similar member(s), the role may be prevented from being created. Thus, embodiments prevent creating and maintaining redundant roles.
