Client authentication require problem
Currently my client side profile is set to request. The certificate issue to me by CA XXX. CA XXX have a chain of three certificates 2 intermediate and 1 root certificate. I converted those 3 CA certificates into bundle and uploaded in Trust root certificates in client side profile also every user browser have these 3 certificates. When ever user hits F5 VS there is a green lock which shows server authentication.
Now client want client authentication. The certificate issued to clients is also issued by the CA xxx. And i have CA xxx chain in my trusted CA bundle so if i set client authentication to required will it work?
Please help in this. Just think one is F5 and client is a windows machine. 1. server authentication is currently working 2. client authentication is demanded.

Please help guys. Each client will have his own certificate issued by the same authority CAxxx and i will have complete chain CAxxx as bundle in my trusted CA will it work? Do i need to put the client certificate as well in the bundle?

yes

no
- In which format I will have to put certificate in browser? and in which tab, personal tab? The certificate presented by F5 to client is CN=10.50.171.5, During client authentication should the client presenting certificate should also have CN= 10.50.171.5? Can I use that certificate in browser which I am using in F5 client profile? can one certificate be used in all client machines or each client will have an individual ceritificate only issued to him
- I opened a support case, he generated tcpdump and ssl dumps, and he said that looks like the client is not presenting the certificate which F5(server) is requesting.
