[cisco-voip] Very Strange SSL Issue...

The requirement of the CN being in the SAN is a browser thing, not a server issue.  It’s also going to be a CA requirement going forward if you buy certs from external CAs.

That makes sense, but I know I’ve done this before w/o issue, albeit I may not have been at precisely the version this server was at in this scenario (single server 10.5.2SU1).

When issuing certs with SANS the CN needs to included as a SAN. FYI

The only SAN was the root of the domain name.. but I removed that and now it works. Oddest thing I’ve seen in a while..

Check and see if the CN is also a SAN.  I’ve seen recent browsers that ignore CN if any SAN is present.

Has anyone ever seen where you put a cert on CUCM/CUCXN/IM&P and the Subject name matches but your browser insists it doesn’t? I can’t figure this out. I checked as best I could for spaces like mentioned in Lelio’s recent thread about a CSR and I have no indication of that.

I honestly don’t have a clue where to go, it’s not really a server issue as the server is just presenting the cert I installed, but I have it on both UCxn and CCM/IM&P. I can’t believe I put an errant space on both servers…
