Explanation:  The Subscriber Agent is trying to replace a certificate used for encryption with one that does not support encryption.

Possible Cause:  You have manually provided a certificate that supports encryption and later have tried to resolve certificates again in ConsoleOne, which has resulted in a standard security certificate being sent to the Subscriber server.

Action:  If you want to provide a new security certificate, use the ZfS Management role in Novell iManager to delete the existing certificate before trying to provide another certificate from the same issuer. See Managing Security Certificates in Policy and Distribution Services in the Administration guide.
