iPrint is not allowing Apache2 to load on a NetWare 6.5 SP2 box.

The full error from the Apache Logs dir, is:
Syntax error on line 7 of SYS:/Apache2/iprint/ipp.conf:
Invalid command 'LDAPTrustedCA', perhaps mis-spelled or defined by a
module not included in the server configuration

the line in ipp.conf is:
LDAPTrustedCA "SYS:/PUBLIC/rootcert.der"

The Broker and Manager load just fine, printing works great, just
can't get the web Side up and running.

This may be a simple question, but what Cert shoudl I export?

Thanks in advance,
