Apple released Mac OS X 10.5 (Leopard) a week ago and for the most part Entourage 2004 is “very compatible” according to There’s a new cat in town on Microsoft’s Mac Mojo blog. However, they also acknowledge that they discovered some code in their Leopard testing and will be releasing an update “shortly”.
Most of the Entourage trouble reports that I’ve read in the Apple and Microsoft online forums are anecdotal but one Exchange bug seems to be validating.
This bug affects users in an Exchange environment where users must import an SSL server root certificate into their Mac OS X keychain. The error reported by Entourage is that the root certificate is not correct. A valid certificate appears in the Keychain Access utility as trusted and unexpired.
Whereas Mac OS X 10.4 users could acquire the server certificate and import it into their x509Anchors, Mac OS X 10.5 users can now import the certificates into the user’s login keychain and the system will trust it. Entourage, however, is not trusting the server.
Although Apple released the Login & Keychain Update 1.0 the day after Leopard’s release, it does not address the certificate issue.
