Role Search
You can use the role search to find a particular role or set of roles, or to get a list of roles and their details. To use this search, go to Setup > Users/Roles > Manage Roles > Search. You can also use role fields as criteria filters and results for Employee searches. For more information, see Use Searches to Audit Roles.
Note:
To see a list of all users assigned a particular role, go to Setup > Users/Roles > Manage Users, and select the role from the Role dropdown list at the bottom of the Manage Users page.
