Carsten Ziegeler commented on SLING-2944:
-----------------------------------------
I'm wondering if we shouldn't remove the support for a header in the manifest
and simply rely on bundle symbolic name? E.g. if a dev knows that the Sling
eventing bundle uses this mechanism to get an admin session (or whatever is
configured), the dev can simply use the header entry and use the symbolic name
of the eventing bundle as the value, using the same configuration as the Sling
eventing bundle.
It's try that once a bundle can be deployed, more or less everything is
possible, but still just relying on the symbolic name makes this concept a
little bit easier, doesn't open the above mentioned door and doesn't make it's
usage more difficult.

> From the start Sling tried to solve the problem of providing services access
> to the repository and resource tree without having to hard code and configure
> any passwords. This was done first with the
> SlingRepository.loginAdministrative and later with the
> ResourceResolverFactory.getAdministrativeResourceResolver methods.
> Over time this mechanism proved to be the hammer to hit all nails.
> Particularly these methods while truly useful have the disadvantage of
> providing full administrative privileges to services where just some specific
> kind of privilege would be enough.
> For example for the JSP compiler it would be enough to be able to read the
> JSP source scripts and write the Java classes out to the JSP compiler's
> target location. Other access is not required. Similarly to manage users user
> management privileges are enough and no access to /content is really required.
> To solve this problem a new API for Service Authentication has been proposed
> at https://cwiki.apache.org/confluence/display/SLING/Service+Authentication.
> The prototype of which is implemented in
> http://svn.apache.org/repos/asf/sling/whiteboard/fmeschbe/deprecate_login_administrative.
> This issue is about merging the prototype code back into trunk and thus fully
> implementing the feature.
