During the course of product evaluations for a customer, the Technology Evaluation Center has uncovered a potential security hole in SAP R/3's three-tier architecture.

If the client does not take these extra measures, the master password for the SAP database instance travels over the network in the clear, and can be captured. PeopleSoft has the same issue.
