Security certificate expiration in Lotus Sametime May 18th 2009

What is happening
The Lotus Sametime Meeting Server applets are signed with a VeriSign certificate that is valid between May 15, 2006 and May 18, 2009. To prevent users who load any of the Sametime applets such as the Meeting Room Client or Directory applet from seeing a warning message as of May 19th, IBM recommends that you apply the fixes provided in the technote (link) below. Otherwise, starting May 19th, Web users will see a dialog with a message similar to one of the following when loading a Web page that contains a Java applet from Sametime:

“The digital signature was generated with a trusted certificate but has expired or is not yet valid.”
“The security certificate has expired or is not yet valid.”

This issue can occur even if IBM is set up as a trusted publisher in the browser.

What does this mean
Please be assured that this message does not mean security has been compromised. It simply reflects the expiration of the signature originally provided in the security certificate used with certain Sametime applets. You can find an explanation in the following technote:

Title: “Sametime applets signer certificate expires on 18 May 2009”

Action needed to resolve
To resolve the situation, you may download fixes from Fix Central and apply them to your system. The technote above provides release specific links, which we recommend you follow. The generic link to the Fix Central main page is:
