Comments

NIH has a de facto standard with eDirectory and AD. AD is the NOS of NIH, with eDirectory playing an important role for some large ICs within NIH.
Reference the Data in the Information Architecture and Data Technology in the Technology Architecture for additional guidance and information.
Some additional areas of concern:
- A DNS (AD) requirement
- Multiple management applications and processes
- Multiple schemas
- Platform limitations
- Lack of standardization for directory and application development.
Tactical and strategic products were selected to leverage NIH's investment in products that are a proven fit for NIH's known future needs. Leveraging baseline products in the future will minimize the operations, maintenance, support and training costs of new products.
Some baseline products have been designated retirement and containment. These products are either not as widely or successfully deployed at NIH, or they do not provide as much functionality, value, or Total Cost of Ownership as the selected tactical and strategic products.
