I have a Cisco ASA 5510 with an IPS module in it. When trying to connect to this unit with ASDM on port 8443 I get an error "Certification Validation Error" and on the popup it is asking for the password. I put in the enable password and then it comes back and asks for the username and password again and you end up in a loop until it comes back and says that it cannot connect to the appliance. I am able to connect to appliance with SSH utilizing the same username and password. My unit is running ASA software 8.2.1 and the 6.2.1 ASDM software.
Any ideas on what I need to correct this error?
