I've setup a Citadel groupware server, plus its WebCit web admin interface. It worked well with HTTPS access. However, I had to reinstall the server, and when I try to access the server again via HTTPS, I get the following error in Firefox:
You have received an invalid certificate. Please contact the server administrator or email correspondent and give them the following information:
Your certificate contains the same serial number as another certificate issued by the certificate authority. Please get a new certificate containing a unique serial number.
(Error code: sec_error_reused_issuer_and_serial)
What can I do on the server side to alleviate this problem? Or is it simply a matter of resetting something in Firefox?? What would be a way to prevent this problem in the first place? Thanks.
