Yesterday I installed a new self signed cert thinking that would help my problems with IE7 thinking my Zimbra was a phishing site (this sucks by the way ....way to go MS!).
I followed the wiki instructions and backed up everything first. Not thinking about my users...whoops....they are now getting errors in Firefox about invalid certificate because of the serial number of the old certificate they have accepted. The only way to fix is to go into Firefox and delete the old certificate. Is there anyway to restore the backup so that what they have on their systems matches Zimbra so they do not get this message. Its a simple fix on the client side but I have over 50 remote offices that I am having to walk them through on the phone (cant get into the email).
