[THREDDS #BTY-229773]: THREDDS - catalog generation of remote sites



Hi Katherine,

You should be able to use the path to the file on disk in the datasetScan 
location attribute rather than using an http URL as you had in the earlier 
datasetScans.

Restricted to you on disk? Or just that outside access needs to be restricted.

We've recently added the ability to restrict access to datasets. We don't 
currently have a way to restrict access to catalogs. Here's a link to more 
information on restricting access to datasets:

You could use Apache Server access control to control catalogs and datasets. 
The TDS access control is a bit more fine grained on what you can restrict but 
as I mention above it can't restrict access to catalogs.

You could use the TDS to restrict datasets and Apache to restrict catalogs. But 
that would mean having to handle user and group/role information in two 
different locations. Not pretty.

The TDS access control scheme allows administrators to plug-in their own 
authenticator (there's a link with more information on the page at the above 
URL). Don't know if that might be useful for you.

Hope this helps,

Ethan
