We're using custom internal auth on our new WiSM and it works great.
The only issue we have is that the self signed certificate prompts warning messages for the user before they can authenticate. We need to avoid this and are looking to get a proper certificate to replace it.
The web page appears to come from the virtual interface - in our case 126.96.36.199
a) is it possible to get a certificate from a certificate authority for this IP address?
b) can the same certificate be used on both controllers within the blade - or will it need two seperate ones?
c) To get a certificate I need to get the CSR to submit, but I can't find it?
You need a certificate that is trusted in your cert store. You might try to look at this. RapidSSL is one that I use alot.
