Certificate validation failure

[ishh]

I have created Vpn profile on Asdm . There are already certificates available and installed .. Identity certificate and CA certificate,,

How I can use the existing certificate for authentication for my VPN profile . When you run VPN wizard , I named new profile name and pointed to device certificate ..and rest is all common steps I took that normally any network engineer used to create new Vpn Profile .. But I am still getting Certifcate validation failure error .. what is the best way to resolve this issue .. 

Thanks

what kind of cert is this ?

Error says , No valid certificates available for authentication .. 

This means something wrong with Certiificate, you need to issue the certificate to user, and installed on the device you trying to connect.

I have provided the document for reference to install Certs - for reference, in case any steps missed.
