Passing Client CAC / Smart Card Cert to Application Server
I am reaching to see if anyone has created or come across the most stream line process of passing a Client cert through F5 which then reaches the an Application server. The most important piece of data that needs to reach the server is just the CN (Common Name) I have looked online and come across many iRules but none seems to work. Example: when CLIENTSSL_CLIENTCERT { # Save the first client cert to a variable. Not sure why, but... set ssl_cert [SSL::cert 0] } More or less, I am looking for an iRule that will just do a "Pass through" for the Client cert through the F5 Proxy that would then reach the Application server. Thanks in advance for the help, I have spend a few hours on this as F5 BIG-IP is still very new to me across the board.

[F5 LTM 11.4.1 HF9][2-Way-auth] CLIENTSSL_CLIENTCERT is not triggered in the Irule
Hello all, I am trying to implement an Irule to filter CN names. below the irule : when RULE_INIT { set static::org "O=OPS" log local0.alert "RULE_INIT" } when CLIENTSSL_CLIENTCERT { Check if client provided a cert if {[SSL::cert 0] eq ""}{ Reset the connection reject } else { Example Subject DN: /C=AU/ST=NSW/L=Syd/O=Your Organisation/OU=Your OU/CN=John Smith set subject_dn [X509::subject [SSL::cert 0]] log local0.alert "Client Certificate Received: $subject_dn" Check if the client certificate contains the correct O and a CN from the list if { ([matchclass $subject_dn contains cn_allowed]) and ($subject_dn contains $static::org) } { Accept the client cert log local0.alert "Client Certificate Accepted: $subject_dn" } else { log local0.alert "No Matching Client Certificate Was Found Using: $subject_dn" reject } } } The "cn_allowed" contains the list of allowed CNs. When I make a new connection with the browser (after sending the client certificate), I am not getting any log in /var/log/ltm related to the CLIENTSSL_CLIENTCERT section (only the rule init is shown). Kindly help me to resolve this problem. Thanks in advance.
