[ckan-dev] fine grain access control

Fri Jun 24 12:50:04 UTC 2016

Hi Richard,

I couldn’t tell you in detail how to implement the scenario you outline,
but generally speaking the IAuthFunctions interface [1] is what you need.
The documentation is not very detailed, unfortunately. We have implemented
some rather heavy-handed code for a CKAN plugin [2] that prevents anonymous
users from seeing anything at all. See in particular get_auth_functions()
and berlin_site_read().

Cheers,
Knud

I have installed CKAN 2.5 onto a linux Ubuntu 14.04 server. The website
talks about CKAN being able to support fine grain access controls but I can
find the implementation details.

The scenario I am trying to get to is:

- All users can perform searches regardless of whether they are signed into
CKAN.
- All the meta data is returned for results that fulfil the search
criteria.
- To download any data from CKAN the users must be registered and logged
into the site.
- Then for some results only specially identified users can access the
underlying dataset.

Any pointers to documentation or code would be most welcome.

Thanks
