Cannot perform post-handshake authentication error on Apache HTTPD

Solution Verified - Updated -


  • We recently changed our Apache 2.4.6 built-in on RHEL 7 to the JBCS 2.4.37 as our JBoss front-end web server. After that change, we realize that the client certificate authorization is not working anymore, and the below error is generated on the JBCS log files:

    [ssl:error] [pid 125757:tid 140436077168384] [client 999.999.999.999:99999] AH: verify client post handshake
    [ssl:error] [pid 125757:tid 140436077168384] [client 999.999.999.999:99999] AH10158: cannot perform post-handshake authentication
