WebDAV servers support role management through Access Control Lists (ACLs), which are used to define different levels of permissions for specific users or groups. Roles can be created and assigned specific permissions, and users or groups can be added or removed from roles as necessary. This allows for granular control over who can access, modify or delete specific files or folders within the WebDAV server. Some WebDAV servers may also support more advanced role management features such as inheritance and propagation of permissions across subfolders, which can save time and effort when managing large numbers of users and resources.
