If I use the locally generated SSL cert on my WLC Internet Explorer always shows the "Untrusted cert warning" when users try to authenticate via the web interface. What can I do to resolve this do I need to buy a cert? If so where is the best and cheapest place to do this? GoDaddy???? Also, I purchased one for my mail server and had to specify a domain name during the process. What would I use for my WLC? The URL during the web authentication process show https://126.96.36.199
RapidSSL is your best bet. It is less than 90 bucks for 1 year with insurance and renewal. 5 years is like 380 bucks. GoDaddy will not work since they use chained certificates.
On the VIP, you would enter the DNS Domain Name as what you used on the certificate CN when generating a csr. Of course, you will have to resolve the CN name to 188.8.131.52 or change the 184.108.40.206 to another ip address that is not on your network. Reboot the wlc and your done.
