Hello,
I ´ve set up a openVPN server according to this tutorial on my VPS.
https://www.bestvpn.com/blog/11447/roll-openvpn-server-vps-using-centos-6/
Everything went well with the official App on Android 4.4.2
But now I need to use my VPN on a older device where this App is not supported.
The ROM I am using (Cyanogen Mod 7) does have a build-in open VPN Client in the Network Config Menu.
You need to import the Certificates from SD Card so I followed this tutorial:
http://openvpn.net/index.php/access-server/docs/admin-guides/228-how-to-extract-the-ca-cert-and-key-from-openvpn-as-certificates.html
And imported them. Didn´t work. There were no errors during import the connection simply doesn´t build up.
Then I found this:

Although I managed to convert these cetrificates to a single .p12 file:

And to install them on my phone, the same happens, it hangs ca. a minute while building up but then it fails.
Any suggestions?
