Rolf, can you please check that all intermediate certificates are installed correctly on your test site?

I think they are missing.
I've manually installed the intermediate cert from

I get a valid "domain validated" connection,
but not a "EV validated" connection.

In the past this commonly meant there were OCSP server problems.
Are you sure your OCSP server is ready for testing?
You've requested OID

but the cert at the test site uses OID

Rolf ?
More problems.
In addition to the EV OID mismatch, I found another mistake.

This bug requests to enable "CA III" for EV,
but the cert at your test site chains to "CA I".

You are right. Obviuously the configuration of https://testserver.universal-iii.trustcenter.de is incorrect.
We are working on that.
I made a new testbuild, now it includes the patch to enable roots for EV.


I've learned that tryserver builds are automatically deleted quickly, after 4 days.
I've mirrored the most important files here:

We have corrected the configuration of 

Please go ahead with testing.
The server does not send intermediate CA certs.

> The server does not send intermediate CA certs.

Looks like I'm wrong.
I was confused by some other failure.
I have a positive test result with your site, I get the green EV identity indicator.

Rolf, please try a test build from comment 8 and confirm that you are satisfied with the results.

We've checked that build (see comment 8) with https://testserver.universal-iii.trustcenter.de

the EV indication looks good.

However, when looking into the root certificate store (Tools | Options | Advanced | View Certificate | Authorities) the TC Universal III Root has been verified for the following uses "SSL Certificate Authority" whereas the TC Universal I Root has been enabled for the following uses "Email signer Certificate", "SSL Certificate Authority" and "Status Responder Certificate".
The trust settings are identical. 

What's the reason for that?

Note: TC TrustCenter Class 2 CA is also verified for SSL Certificate Authority only, but has the same KeyUsage extension as TC Universal III.

I haven't attempted to debug, but I used certificate viewer to compare properties.

"Root 1" includes cert key usage "Signing", but "Root 3" does not.
This might explain it?

I don't think so, because TC TrustCenter Class 2 CA also has this KeyUsage but is only verified for SSL Certificate Authority.

Correction: TC TrustCenter Class 2 CA is also verified for SSL Certificate Authority only, but has the same KeyUsage extension as TC Universal I
(not TC Universal III as I stated above).
Critical: Signing, Certificate Signer, CRL Signer.
Sorry, finding the response for your answer will require that an expert traces the internals of NSS.

If you are worried and think this is an issue, you must wait until we get to it (no schedule) (or you could hire someone to do it for us sooner).

You have the option to get your roots added anyway, by confirming in bug 593063 and this bug 593067 that you are satisfied with the test build.

If not, you'll have to wait.

The issue existed before that and is not limited to the TC Universal III root.
No need to wait with the EV root.

Adding the TC Universal III root was successful for us.
