ShibAccessControl Relative Paths to user web content
----------------------------------------------------

                 Key: SSPCPP-425
                 URL: https://issues.shibboleth.net/jira/browse/SSPCPP-425
             Project: Shibboleth SP - C++
          Issue Type: Improvement
          Components: Request Processing
         Environment: Redhat 5/6 - default packages. 
Currently using Shibboleth SP 2.4.3

            Priority: Minor


When using ShibAccessControl in a .htaccess file in our environment we encourage web content maintainers to place the xml file in the same location as the content they are maintaining (with a blocked file naming standard of course)

Unfortunately this requires a full path to the location where the .htaccess file already is. This causes issues with development, testing and production environments potentially having different root file paths.

We would like to be able to reference the .xml relatively based on the location of the .htaccess

As discussed this could not be the default option as it would break exist config for other users
- so just as a suggestion - maybe a new ShibAccessControlPath option - which defaults to the currently used /etc/shibboleth
- can take a new base file path or be set to AUTO to go off the .htaccess location 



Below are some details about how to maybe get the current location of the .htaccess file (or <Directory> path etc)

"A cmd_parms structure is the first argument passed to all directive handlers"
"char* path"
"If the handler is being called to process a directive located in an access control file, 'path' will contain the path to the directory containing the .htaccess file"
