On what machine are you trying to use the ipa tool? Is it one of the

It's the same error message when the "ipa" command is run directly on any of 
the masters.



And it's the same error message if I run the "ipa" command on any of the 
clients.



I do not have a working "ipa" command anywhere anymore.



Ok, let's test out the cert that ipa is using. Try this on any one of
the masters:

$ curl https://`hostname`/ipa/xml
Should fail with Peer certificate cannot be authenticated with known CA
certificates

Yes, this did not work:


curl: (60) Peer certificate cannot be authenticated with known CA certificates
More details here: http://curl.haxx.se/docs/sslcerts.html




$ curl --cacert /etc/ipa/ca.crt https://`hostname`/ipa/xml
Should succeed in that you get the "you are not logged in" HTML page



Indeed - this works.



Ok, now unfortunately curl only handles the sql-style NSS databases so
we can't fully reproduce it the same way that the IPA client is doing things, 
but here is an
approximation:



# certutil -A -d sql:/etc/pki/nssdb -n 'IPA CA' -t CT,C,C -a -i
/etc/ipa/ca.crt
$ curl https://`hostname`/ipa/xml
You should see the login page HTML



Yes, I can now see the login page HTML.




If you stick a -v in there it'll give you more verbose output which
would be useful if any of these fail in an unexpected way.

Whatever is going on isn't likely related to the web server Apache
database as you get the same error out of each one. The client log you sent 
confirmed that
it tried to contact each master. The SSL error we're getting is that the client 
doesn't
trust the CA that
signed the server certificate so this appears to be a problem on the client, 
which begs the
question: all clients or just this one?




All clients.





NSS is smart enough to handle multiple certificates, it should pick the
newest one on startup.


Ok.



Where do you suggest I continue troubleshooting this issue?



We can also tackle this on the server side. Let's verify the server cert:



# certutil -V -u V -n Server-Cert -d /etc/httpd/alias


This produces the same output for all 3 servers:


certutil: certificate is valid



This is verified on server startup so I expect it to be valid, but
doesn't hurt to try.

Restarting the Apache process might be something to try as changes to
the NSS database aren't picked up until a restart.


I ran "# certutil -A -d sql:/etc/pki/nssdb -n 'IPA CA' -t CT,C,C -a -i 
/etc/ipa/ca.crt" on ipa03,
  and restarted httpd.

The "ipa" command is now *working* on ipa03. :)


However it's *not working* a client who's /etc/ipa/default.conf points at ipa03.


Do I have to refresh the PKI CA in /etc/pki/nssdb on every client?

You shouldn't need to. Frankly I'm surprised this worked. What is the distro and what version of nss is installed?
