Client Authentication. IE8 and machine certs

Hello -I am very new to the F5 world, so bear with me :)

 

 

Have just got client authentication working to the F5, but only if a user cert is used. Is there any way the F5 can be configured to look at the machine cert or is there any way that IE can be configured to offer the user cert.

 

 

What I am seeing at the moment is when I browse to the VIP, IE8 allows me to choose only the user certs, and not any machine certs which are located in the 'Local Computer' store.

 

 

Any thoughts welcome

 

 

many thanks
