I'd like to set Subversion properties based on variables calculated by Apache Web Server. Some might set REMOTE_IP to client:ip or REMOTE_DN to client:dn.
In my usecase, I'd like to set along with svn:author svn:author-display-name (or similar). This can be set by our authentication module as REMOTE_DISPLAY_NAME along with REMOTE_USER. In turn, WebSVN should display that value instead of the author which might be a cryptic username.
The current workaround I see for my usecase only is to create a post commit hook, do another roundtrip to Active Directory and read out displayName. A performance degragation I'd like to avoid.
