Hello, I'm using JBoss 4.0.5. I was using previously the 4.0.3SP1 and had the same problem. I have configured a connector with client authentication <Connector port="443" address="${jboss.bind.address}" maxThreads="100" strategy="ms" | maxHttpHeaderSize="8192" emptySessionPath="true" scheme="https" secure="true" clientAuth="true" | keystoreFile="server.keystore" keystorePass="changeit" sslProtocol="TLS" | truststoreFile="server.truststore" truststorePass="changeit" /> Client side, it's working fine with IE and Firefox, I have the client certificate request. The problem arise when I have about 300 to 350 users declared in the truststore. With Firefox, it's still working fine but with IE, I have immediately the message : "Cannot display the page". Not even waiting for a few seconds. Do you have an idea to avoid this problem ? I don't understand why it's not working only with IE. A different timeout value ? Thanks in advance for your help.
