From Concepts to Implementation
 How applications use the Metadata server for
User Authentication.
 Credential management to support single signon.
 Case Studies
Copyright © 2005, SAS Institute Inc. All rights reserved.
What is a Metadata Server?
 Secure access to your Enterprise business and
technical information
 What is modeled in Metadata?
• Configuration
• Physical Locations
• Business Intelligence
• Delivery
• User identities
Copyright © 2005, SAS Institute Inc. All rights reserved.
Metadata Server Authenticates Connecting Clients
 Verifying user ‘is who they claim to be’
 Typical authentication providers:
• Host Operating System
• Directory Servers
• User ID and password databases
 SAS 9 Metadata server supports:
• Host OS Authentication
• LDAP
• Microsoft Active Directory

 Login object represents authentication credential
User ID

Authentication
Domain
 Associated with user identities
User: Fred Smith

Reducing the presence of credentials in Metadata.
Strategies
 Caching Log-on credentials at the application
Works when cached credentials are valid for the
servers User needs to use.
 Group logins
Application checks for single sign credential in this
pattern:
Does User have a login that matches the auth
domain?
User a member of a Group with matching login?

Case Study One: Information Map Studio
 Testing an information map that is based on a
SAS dataset accessed through a SAS 9
Workspace Server
 Strategies to reduce credentials stored in
metadata repository:
• Caching of log on credentials by the application
Copyright © 2005, SAS Institute Inc. All rights reserved.
Information Maps
Map
 User-friendly metadata definitions of physical
data sources
 Enable your business users to query a data with
meaningful names
 User presentation meets specific business needs
 Created in Information Map Studio
Copyright © 2005, SAS Institute Inc. All rights reserved.
User Groups and BI Workflow
 ETL team builds data warehouse, mart, etc.
 Information Architect determines business needs
for accessing data and builds Information Maps
with Information Map Studio
 BI Analysts use Information Maps in Web Report
Studio to build web-based reports
 Business Users review reports for decision
support
