I have recently upgraded to the latest VisualSVN server (on Windows) and now when I try to connect to it from my Linux svn command line client, I get this error:
svn: OPTIONS of 'https://server:port/svn': SSL negotiation failed: SSL error: Key usage violation in certificate has been detected.
I've tried downloading the PEM crt file and adding it in ~/.subversion/servers (using the ssl-authority-files) but this does not work either.
Does anyone have any suggestions?
Tekken666's suggestion did not work for me since I am on a shared environment (so I can not delete files in /usr/lib).
However, I got around my issue by simply recompiling subversion from the latest code. The problem seems to be that the svn on my hosted server was using a GNU SSL library instead of the default neon SSL library. Neon is less strict than GNU when it comes to certificate issues.
You can regenerate the certificate so it will be considered valid by GnuTLS. See the VisualSVN Server KB article "VisualSVN Server certificate key usage violation in Subversion clients built against GnuTLS".
-1 Uninstall the current libneon package: sudo apt-get remove libneon27
-2 Download the latest libneon package from http://packages.debian.org/squeeze/libneon27 (at the bottom you can choose the right version for your architecture). Install the required libssl dependency: sudo apt-get install libssl0.9.8
-3 Install the downloaded libneon package. E.g. for the 64Bit architecture: dpkg -i libneon27_0.29.3-3_amd64.deb
-4 Change the symbolic links again like described above: sudo mv /usr/lib/libneon-gnutls.so.27 /usr/lib/libneon-gnutls.so.27.old sudo ln -s /usr/lib/libneon.so.27 /usr/lib/libneon-gnutls.so.27
