Hudson is unable to access a subversion repository secured by ssl client
certificates. It fails with a handshake error.

As far as I know Hudson is using svnkit for accessing svn repos.
Svnkit should use the ssl config from ~/.subversion/servers.
I ran hudson with ssl-debug and saw that the client cert is never sent.
I traced the hudson java-vm with linux strace and saw that the svn
servers-config is never read.
With hudson 1.261 svn authentication worked. Using 1.304 I could not access out
repo.
