I am confused regarding certificates and am unclear if I need to be
concerned about a cert being expired. I have several systems setup with
SLES 10 and OES2. Specifically when I go under Yast | Security and
Users | CA Management | Enter CA | and then Under the Certificates Tab
it tells me my certificate is expired.

But if I go to this server via iManager or Netstorage and click on view
certificate. They are just fine. Now I believe they use SSL
CertificateDNS and SSL CertificateIP.

So I am confused at what is actually expired and whether I need to
address this and if so what uses this and what do I have to do to fix it?
