CumulonimbusHi
I did not test it, but something like this should help :
when CLIENT_ACCEPTED {
set clientCertPresent 0
}
when CLIENTSSL_CLIENTCERT {
set subject_dn [X509::subject [SSL::cert 0]]
if { $subject_dn != "" }{
set clientCertPresent 1
}
}
when HTTP_REQUEST {
if { [HTTP::uri] starts_with "/uri1" || [HTTP::uri] starts_with "/uri2"} {
if {not [matchclass [IP::remote_addr] equals NOCERT_IP_LIST] && $clientCertPresent equals "0" } {
SSL::session invalidate
SSL::authenticate always
SSL::authenticate depth 9
SSL::cert mode require
set cmd "SSL::profile /Common/require_clientssl"
eval $cmd
SSL::renegotiate
event disable all
} else {
HTTP::redirect "https://my.error.page.com/error.htm"
}
}
}
}hope this helps.

MVPAlso if Op like to capture CN alone, he can go with first checking if there was any cert provided at all, [SSL::cert count] > 0. based on that trigger the if block, if it passes, then capture the CN or entire subject accordingly. If planning to capture CN, here,
[findstr [X509::subject [SSL::cert 0]] "CN=" 3 ","]And if you want to throw a custom page, just go with this,
HTTP::respond 403 content "<html>The requested URI - [HTTP::host][HTTP::uri] is restricted, your provided client certificate (CN=[findstr [X509::subject [SSL::cert 0]] "CN=" 3 ","]) is not allowed to access. Contact admin</html>"Thank you for the reply. Unfortunately I was not able to make this rule work for me. Perhaps I can elaborate on my goals. We can ignore the URI condition as it's not the most important part.
First: if IP is on NO_CERT_IP_LIST then allow access without client certs (using ignore_cs_ssl_profie?)
Second: All other IP's will require client certs (require_cs_ssl_profile?). if there are any ssl errors at this stage then the client should be redirected to an html error page. This would include wrong cert or no cert errors.
Thank you!
In the VS I have an ssl profile assigned and set to ignore client certs as the default. The IRule I have working now selects a different ssl profile that requires client certs based on the condition of the data group and URI. This works as intended except I am not able to redirect to custom error page.
