Hoping someone can help, I've spent days trying to get this working but all suggestions on wiki and forums seem to fail.
I've tried adding subjectAltNames via the Admin Console but they never seem to work (or show under view certificates).
I've tried using zmcertmgr createcsr, but as soon as I add -subject or -subjectAltNames parameters, the command returns as if I have invalid syntax.
Is there a problem with subjectAltNames under 5.0.16 of Zimbra? Can anyone point me to instructions or a wiki entry that has worked for them?
