No group integraton into Subversion

Currently it is possible to globally authenticate subversion DAV based repositories against Crowd using the Auth::Crowd module. However if you wish to maintain more fine-grained group-based access (i.e. "members of group A have read-only access to sub-tree /foo/bar", etc) you need to maintain a separate file that duplicates the users and groups that are in Crowd (i.e. AuthzSVNAccessFile). This is messy, duplicates work and is error-prone.

There are a couple of ways forward on this:

• Implement CWD-391 and limit access within the Apache config via <location> blocks.
• Implement CWD-204 and provide an example script that can generate the appropriate group mappings by querying the crowd server
• Duplicate mod_authz_svn functionality in the Auth::Crowd::Module
