new multiforest ldap setup erring out when running ADAMSYNC /INSTALL

I am attempting to set up a new multiforest ldap instance, based on the following document. The configuration goes as planned untill I attempt to run ADAMSYNC /install.

I have reduced to attributes portion of the xml file to nothing and still receive the error. Any help in understanding how to resolve this issue is appreciated.
