#1: Certs work, one doesn"t, cannot determine why

Posted on 2010-10-15 23:49:33 by Jeff Blaine

Hi folks. I'm *really* stumped here. If anyone has any
ideas, I would love to hear them. How can I debug this
further? I need more information that Apache + mod_ssl
is giving me right now.

All version information and configuration detail is after
this next paragraph.

Works: SSL via my corporate cert, SSL via 3 other people's
corporate certs
Fails: 1 person's cert so far, yet is logged as "SUCCESS"
when logging SSL_CLIENT_VERIFY via CustomLog

Example:

[15/Oct/2010:09:53:38 -0400] 1xx.xx.160.92 on TLSv1 RC4-MD5 128
/O=our.org/OU=People/UID=mbs/CN=Simpson Mary B SUCCESS 3 452E Simpson
Mary B - "GET /index.html HTTP/1.1" 295

[Fri Oct 15 09:53:38 2010] [error] [client 1xx.xx.160.92] access to
/apps/rtsrv1dev/share/html/index.html failed, reason: SSL requirement

Still trying to solve this, I stood up a separate
brand-spanking-new Apache 2.2.17 from source with builtin
SSL. I am using the same Apache SSL config as quoted below.
I experience the following failure (further context is in
my quoted message below):

Your verbose description of "something goes is not working" is hard to
follow or condense down. Are you saying with the below configuration,
you are seeing the SSLRequire work for all the users but that with the
jblaine cert?

It could be an SSLRequire implementation bug but it is hard to tell. Is
the order of the users within the SSLRequire list significant? Why are
you matching by the whole S_DN rather than based on e.g. S_DN_CN alone?

You might be better off trying the httpd users' list:

http://httpd.apache.org/lists.html#http-users

I was originally seeing it work fine for everyone but 1 user
(Simpson Mary B, below). Now it almost seems somewhat random
in failure. People who used to succeed are now failing.
I can get in fine (Blaine Charles J.)

Granted, I am messing with all sorts of things trying to get
it work after all this time dead in the water.

Ah, you mean if I reorder them, does the success/failure
situation change as well? I don't know, I can try that.

Why not? It seems like the more fully correct way to match
for security. It's documented and supposedly legit/correct.
The cert-extracted DN (reported in log) matches the configured
DN in the ssl.conf file exactly.

I will try the httpd list.

Thanks Joe
Jeff
