We were trying to use a certificate server to authenticate and it worked fine, until we had a single client certificate. To test I used another iphone and a new certificate, and configured it exactly as the one which was working (different certificate ofcourse). Using the Junos Pulse I am getting a message: Timed out! Retry?Ó and NO or YES options, and immediately after that I get: VPN Connection The server certificate has expired. Contact your network AdministratorÓ. However when I launch the browser and login to the SA2000 using the same certificate I am able to get in. So the certifcicate seems to be ok. Is this some bug in the Pulse client or something I can do to make it work? My work around: During troubleshooting, I changed the authentication method, to LDAP authentication, it worked and when I switched back to Certificate authentication it worked only when I had entered the complete credentials for LDAP in my previous step. [Note my certificate issuing server is same as the AD.] Now this work around is unreliable and not practical, and if I delete the working configuration and add it back again I again start getting the same errors on Pulse, at the same time using the browser (using the certificates) it works with no issues. I am using version 2.0.0.8059 for Pulse And version 4.2.1 (8C148) for our iphones. Any ideas? Known Bugs? ... View more
