+++ This bug was initially created as a clone of Bug #619241 +++

Description of problem:

    Accessing https://www.flores-associates.com/ results in the message
    "This Connection is Untrusted."  The "Technical Details" section says:

        www.flores-associates.com uses an invalid security certificate.

        The certificate is not trusted because the issuer certificate is 
        unknown.

        (Error code: sec_error_unknown_issuer)

    However, the certificate chain appears to be valid.

Version-Release number of selected component (if applicable):

    nss-3.12.6-7.fc12

How reproducible:

    100%

Steps to Reproduce:

    Point Firefox to https://www.flores-associates.com
  
Actual results:

    SSL problem

Expected results:

    No problem.  Web page should load.

Additional info:

    Downloading the certificate chain with "openssl s_client -connect
    www.flores-associates.com:443" results in the following chain:

        depth=3 C = US, ST = UT, L = Salt Lake City, 
        O = The USERTRUST Network, OU = http://www.usertrust.com, 
        CN = UTN - DATACorp SGC

        depth=2 C = SE, O = AddTrust AB, OU = AddTrust External TTP Network, 
        CN = AddTrust External CA Root

        depth=1 C = GB, ST = Greater Manchester, L = Salford, 
        O = COMODO CA Limited, CN = COMODO High-Assurance Secure Server CA

        depth=0 C = US, postalCode = 28231, ST = NC, L = Charlotte, 
        street = PO Box 31397, O = Flores & Associates, 
        OU = EliteSSL, CN = www.flores-associates.com

        Certificate chain

        0 s:/C=US/postalCode=28231/ST=NC/L=Charlotte/street=PO Box 31397/
        O=Flores & Associates/OU=EliteSSL/CN=www.flores-associates.com
           i:/C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/
           CN=COMODO High-Assurance Secure Server CA

        1 s:/C=GB/ST=Greater Manchester/L=Salford/O=COMODO CA Limited/
        CN=COMODO High-Assurance Secure Server CA
          i:/C=SE/O=AddTrust AB/OU=AddTrust External TTP Network/
          CN=AddTrust External CA Root

        2 s:/C=SE/O=AddTrust AB/OU=AddTrust External TTP Network/
        CN=AddTrust External CA Root
          i:/C=US/ST=UT/L=Salt Lake City/O=The USERTRUST Network/
          OU=http://www.usertrust.com/CN=UTN - DATACorp SGC

    The issuer of certificate #2 in the chain ("AddTrust External CA
    Root") is already in Firefox's CA database, so the certificate
    chain should be valid, but it seems to be rejected for some
    reason.

For what it's worth, I can access the Web site in RHEL 5.5 with firefox-3.0.16-1.el5_4 and nss-3.12.3.99.3-1.el5_3.2

--- Additional comment from emaldona on 2010-07-29 15:23:58 EDT ---

I can access it with firefox-3.5.11-1.fc12.x86_64, nspr-4.8.4-2.fc12.x86_64, and nss-3.12.6-7.fc12.x86_64

--- Additional comment from bmason on 2010-07-29 18:00:13 EDT ---

Interesting.  I'm still denied access with:

# rpm -q firefox nspr nss
firefox-3.5.11-1.fc12.x86_64
nspr-4.8.4-2.fc12.x86_64
nss-3.12.6-7.fc12.x86_64

--- Additional comment from emaldona on 2010-07-30 12:56:03 EDT ---

This is trange we have the same versions of firefox, nspr and nss. I bet your system is far from pristine.  I tried also on a RHEL-6 Beta 2 system and Fedora 13 without any problems. I used relatively clean virtual sytem. I had export NSS_DEFAULT_DB_TYPE="sql" on and tried with it commented out on my ~/.bashrc file so legacydb versus shared db doesn't matter, not that we expect it to matter at all.

--- Additional comment from kdudka on 2010-08-03 09:10:10 EDT ---

Bryan, could you please try it with curl?  Does it make any difference?

$ curl -svo/dev/null https://www.flores-associates.com

I performed the suggested test and it fails whereas it was working using the broser. Here are my annotated results

I connect via curl
[emaldona@localhost ~]$ curl -svo/dev/null https://www.flores-associates.com

* NSS error -8179
* Closing connection #0
* Peer certificate cannot be authenticated with known CA certificates

Notice the "WARNING: failed to load NSS PEM library libnsspem.so."
Something is preventing the PEM module from getting loaded. I have a suspect.
I then check to see if nssysinit module is enabled
[emaldona@localhost ~]$ sudo cat /etc/pki/nssdb/pkcs11.txt | grep library
library=libnsssysinit.so

It is enabled, Let's then turn it off.
[emaldona@localhost ~]$ sudo /usr/bin/setup-nsssysinit.sh off
And verfiy it is off.
[emaldona@localhost ~]$ cat /etc/pki/nssdb/pkcs11.txt | grep library
library=
This tells me that it is disabled.

Repeat the test

This time it works. The nss-sys-init module being active seesm to be preventing the pem module from getting loaded. I have also observed the failure to load the PEM module on and off while testing a patch I'm working on to make the PEM module automatically loadable by nssysinit.

Sure, FF does not use libnsspem.so to load root CA certificates, curl does.  That's it.  If it stopped working after an update of nss, you should look for the problem in nss.  I am not aware of any changes in libcurl itself, except the one for NTLM support, which required the NSS initialization scheme to be slightly changed:

http://github.com/bagder/curl/commit/f3b77e5

--- Additional comment from emaldona on 2010-08-03 13:07:27 EDT ---

It is a bug in nss-sysinit and we seem to have a fix thanks to the patch contributed by David Woodhouse for [Bug 603313] that I have been testing. I was able to connect okay with nss-sysinit turned on once I tried the nss build with his patch.

I'm still getting an Untrusted Connection message when I try to open https://www.flores-associates.com/ in Firefox.  When I get the certificate and view the certificate hierarchy, it looks like:

    UTN - DataCorp SGC
      AddTrust External CA Root

curl seems able to work properly, though:

And Firefox still fails.

So is this some sort of configuration problem with my Firefox?

Well that's interesting.  If I create a new Firefox profile and run Firefox with that profile, I can access the site with no problems.
