Hi all,
one of our institutions wants to use a specific "outer" ID for EAP-TLS.
(Technical background: The server root certificate expires and they want to migrate to a new root using a switch by outer ID)
They use their own certificates, but want to use CAT for configuring the devices. On Windows they noticed that the installer does not honor the outer ID configuration, apparently the Windows installer doesn't even include this.
From what I heard from the admin, windows needs a specific "DifferentUsername" property to not use the CN/UPN/... from the certificate.
Does the windows installer support it already and we're just holding it wrong?
If not: Is this something that the windows installer could be doing?
Cheers,
Janfred
