OptRenegotiate - enables avoidance of unnecessary handshakes by mod_ssl
which also performs safe parameter checks. It is recommended to enable
OptRenegotiate on a per directory basis.

"also performs safe parameter checks" maybe the key. 
disable it and check if MSIE likes it.

Subject: Apache "SSL3_ACCEPT:unsafe legacy renegotiation disabled"?

Hi there

We have a CentOS-4.8 server that was upgraded to
httpd-2.0.52-41.ent.7.centos4 this week - along with dependencies like
openssl-0.9.7a and openssl096b

At that moment our client-certificate based authentication Webapp broke :-(

It's really weird. Users running Firefox-3.5+ or Chrome are still
working fine - but MSIE7 and MSIE8 now get that useless MSIE error page
and Apache reports lines like

[Thu Apr 01 12:41:41 2010] [error] SSL Library Error: 336068931
error:14080143:SSL routines:SSL3_ACCEPT:unsafe legacy renegotiation disabled

Obviously this is related to the SSL renegotiation bugfix - but Google
cannot find anyone else seeing this - so I'm thinking we have some
peculiar to us?

Our Apache config states

<Location ~ "/(ssl_secure/)">
        SSLVerifyClient require
        SSLVerifyDepth 1
        SSLOptions +StrictRequire +StdEnvVars -ExportCertData
+OptRenegotiate
</Location>

So when you attempt to access https://server/ssl_secure/ - you are asked
for your client cert.

We have another section of the site that has "SSLVerifyClient optional"
and that also triggers the same fault in MSIE - and FF/Chrome work fine :-(

Help?

Thanks!
