HCII designed and developed a distributed global directory service(DGDS) product for use in IBM’s ISSC outsourcing business. This product enabled ISSC to implement a single distributed global directory service in an environment where multiple heterogeneous directory and messaging systems are already in use.

The DGDS is built with industry standard interfaces such as X.500, LDAP, and NIS. The DGDS runs on distributed heterogeneous hardware and software platforms, e.g., MVS, RISC 6000, AIX, MS Windows, and Windows NT. The distributed datastores are in Sybase, DB2 MVS, and AIX, and native directory service formats for OpenMail, Profs, MS Mail, MS Exchange, CC Mail, Lotus Notes, and Unix Mail.
