Eric Norman updated SLING-1555:
-------------------------------

    Affects Version/s: JCR Jackrabbit User Manager 2.1.0

> Users and permissions manipulation API
> --------------------------------------
>
>                 Key: SLING-1555
>                 URL: https://issues.apache.org/jira/browse/SLING-1555
>             Project: Sling
>          Issue Type: Improvement
>          Components: API
>    Affects Versions: JCR Jackrabbit User Manager 2.1.0,  JCR Jackrabbit 
> Access Manager 2.0.4
>            Reporter: Fabrizio Scarcello
>              Labels: accessmanager, api, programmatically, service, 
> usermanager
>
> It would be nice if the jackrabbit.accessmanager and jackrabbit.usermanager 
> bundles expose OSGI service(s) that maps exactly the functionalities of the 
> REST services, so that one can use their features also in a programmatic way. 
> This can be useful if an application has to manage users and permissions 
> without having an explicit request object (ex: from an EventListener), or in 
> the case a user has to manipulate his account (in this case he doesn't have 
> an administrative account, so his requests are not permitted to modify 
> users). Also i think that, in certain situations, it could be just cleaner 
> and simpler to write a servlet or script that directly invoke the methods, 
> instead of find the way to invoke the REST services.
> I think a simple but exaustive way to achieve this can be the direct mapping 
> of the REST services described in 
> http://sling.apache.org/site/managing-users-and-groups-jackrabbitusermanager.html
>  and 
> http://sling.apache.org/site/managing-permissions-jackrabbitaccessmanager.html,
>  only using well-known JCR classes.
> For example, obtaining the users list could be as simple as getting the 
> UserManager OSGI service and invoking a method like "public NodeIterator 
> listUsers()", changing a permission could be achieved by getting the 
> AccessManager OSGI service and invoking a method like "public void 
> modifyPermission(String node_path, String principalId, String privilege_name, 
> String privilege_value, String order)", and so on...
> Perhaps the best way to standardize these services is a dedicated API that 
> formalizes the underlying concepts (ex: User, Group, Privilege and 
> NodeAccessControl... if you think it's the case, i could propose my own...), 
> but i think the simple REST services mapping could already be a nice (and 
> ready-to-go) feature for developers...
