We are attempting to install certificate support in a new implementation of DS-289 and are receiving the following error.

[18/Apr/2013:00:21:24 +0000] - SSL alert: CERT_VerifyCertificateNow: verify certificate failed for cert server-cert of family cn=RSA,cn=encryption,cn=config (Netscape Portable Runtime error -8016 - unknown)

Any suggestions on where to look or what is causing this would be appreciated
