Hi Venkata,
Please help me with below details for better understanding.
Certificate : ISSUED TO , ISSUED By ?
And site name, if you are accessing the applicaiton with other than certificate issude name then u will receive cerificate warning message.
Try to access the application with ceritificate issude name, warning message will disappear.
Still if you are facing any problem, let me know. Recently i have resolved this problem in my environment.
Thanks,
Chinna.
