Subject Re: SSL with multiple Tomcat instances
Date Tue, 25 Aug 2009 00:31:24 GMT
Hi Don,

A few questions:


1) Does server.xml reference the appropriate IP and keystore for "webui"?

2) What's the output of: [ openssl s_client -connect 
webui.ashland.edu:443 ] from the box, more specifically just the top 
area that mentions the certificate chain. It should look something like 
this...

---
Certificate chain
  0 s:/C=US/ST=Ohio/L=Ashland/O=Ashland University/OU=Administrative 
IT/CN=webui.ashland.edu
    i:/C=ES/ST=Barcelona/L=Barcelona/O=IPS Certification Authority 
s.l./O=general@ipsca.com C.I.F.  B-B62210695/OU=ipsCA CLASEA1 
Certification Authority/CN=ipsCA CLASEA1 Certification

3) Have you stopped and started the instance in question each time you 
made a change to the certificates(keystore) or the server.xml file?


I don't see any issues with the way you generated the keystore, CSR or 
how you imported the certificates as that's how I would do it. It's 
pretty much the way Comodo, Verisign, Thawte, and DigiCert suggest you 
do so.

Without knowing what the server is presenting, it is hard for me to tell 
you exactly what's wrong. As per RFC2246(TLS protocol), in a chained 
certificate environment the server must present the full chain (just 
Intermediates, Root is optional.) so that all RFC compliant clients 
(Chrome, Firefox, Opera, Safari, etc), can connect easily. (Internet 
Explorer actually tries to go behind the scenes and grab the 
intermediates from WindowsUpdate) Using OpenSSL's s_client command, 
should open things up a bit more and provide us with good information to 
use.

one certificate) it looks the same except that it is missing the tomcat (the first instance)
certificate and only has the webui certificate.
