I've just made an interesting discovery after suffering the ignomy of having an SSL certificate expire. (Supposedly I'll have it within the next two hours. A late night for me!) It appears from my testing that the expiry time on a certificate is taken from the client's machine time, not the server time. I've tested this with IE 5.01 SP1 and Netscape 4.77. Therefore the moral is to ensure that you renew all certificates before the time on the certificate is reached anywhere in the world, to prevent browser warnings. In practical terms this would mean renewing before the last 24 hours of the certificate is reached. As far as I am aware this is not documented anywhere. (No doubt some clever person will point me to the RFC where this is). I believe I'll have some accurate information about self-signed starred certificates with IIS fairly soon also. - John Airey Internet Systems Support Officer, ITCSD, Royal National Institute for the Blind, Bakewell Road, Peterborough PE2 6XU, Tel.: +44 (0) 1733 375299 Fax: +44 (0) 1733 370848 [EMAIL PROTECTED] - NOTICE: The information contained in this email and any attachments is confidential and may be legally privileged.
