after starting novell-zdm-inv inventory service dies,

Log gives me the following error:

[7/4/08 15:20:37.699] ZENInv - Service Loader: LDAPNDSUtils: setSSLTruststoreProperties: setting truststore to /etc/opt/novell/zenworks/inv/ssl.keystore
[7/4/08 15:20:37.866] ZENInv - Service Loader: LDAPNDSUtils: createInitialContext: Naming exception.
javax.naming.CommunicationException: anonymous bind failed: ZEN:636. Root exception is javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: Couldn't find trusted certificate

We have change certificate server, and I probably need to change (rebuild) ssl.keystore file in context of new ssl server certificate.

Please help me, how to do that.
