Mountain Lion (10.8) certificates-based L2TP over IPsec VPN kaput
After upgrading to Mountain Lion, my certificates-based L2TP over IPsec VPN stopped working. However, it works fine using a PSK instead of certificates. OSX 10.7, as well as Windows clients have no trouble with the certificates. For OSX 10.8, the VPN server is complaining the payload is faulty. So, since this works fine for OSX 10.7 and Windows clients, I have to conclude that the Mac client is mangling the certificate payload in 10.8.
In the Mac logs, I see the same as the user in this thread: https://discussions.apple.com/thread/4139538?answerId=19058470022#19058470022 . I have also followed the suggested solution in that thread of allowing all applications access to the private key in the Keychain, to no avail, the issue persists and the logs are unchanged.
Any ideas?
Cheers.
