OpenVPN - certificate purpose validation required
Way too many threads every week with users posting about "my OpenVPN does not work", boiling down to
error=unsupported certificate purpose
I can see cert_get_purpose() in certs.inc, this or some similar function should be used to validate the OpenVPN server/client configuration before letting users save it.
Prioritize and separate server certs for OpenVPN servers to make it more clear they should be using certificates created as Server certificates for this purpose -- it's still valid to use non-server certs but it's not what most people intend to do. Ticket #5602

The problem with that is that it's not technically a requirement to use a server cert -- it's only required if the clients verify the server certificate type (which the export package does)
So we could be better about highlighting which certs are server certs (perhaps listing them first or styling them in some way) but we unfortunately we can't stop listing non-server certs there or it could break some setups.
We could also have the export package test the server cert type and omit the directive if they didn't use one, but I'd rather not encourage that practice too much.

- Assignee changed from Jim Pingle to Steve Beaver
- Priority changed from Normal to Very Low
- % Done changed from 0 to 80
I pushed a change to separate, identify, and prioritize the servers in the list of certificates on the page. Passing this off to Steve Beaver since he had an idea for printing a pretty warning if they pick the wrong kind.
I'll also look into adding a warning to the OpenVPN client export package in the meantime.
Lowering the priority since the formatting isn't a huge concern now that the rest of the work has been done.
