When I try to use Firefox to access any SSL-protected resources on my
OES/SP2 server (e.g., iManager), I get an "invalid certificate" popup.
It says "Your certificate contains the same serial number as another
certificate issued by the CA. Please get a new certificate containing a
unique serial number."

Interestingly, IE doesn't seem to mind. Is this a bug in Firefox or a
bug in OES/Linux?
