Novell Messenger 3.0
After a new installation Novell Messenger 3.0 clients are unable to connect to a Novell Messenger 3.0 backend. The client will get the spinning icon and never move beyond that point. If a Novell Messenger 2.0x client is available, it is capable of connecting.
Replace the existing certificates used by the Messenger system and re-mint newer certificates using a minimum of 2048 bit encryption. Steps for doing so can be found in the documentation here.
With SSL changes that have been made to Novell Messenger 3.0, the client requires a higher bit encryption of certificates on the backend. It is known that 512-bit encryption is not sufficient...recommended encryption strength is 2048 bit encryption.
