  1. Windows 2000 Active Directory Services Usage Guide version = 09Dec99 status = in progress

  2. Why this Talk • Review what W2ks Active Directory Services (ADS) enables and what it is • Review how W2ks ADS might effect how existing services are designed, deployed and managed • Review some implementation details we have learned • Discuss what services could make sense to start developing or piloting or today?

  3. Agenda • What is the Microsoft Active Directory Service • Directory Enabled Networking / Policy Based Management • Policy Based Management Development Roadmaps • Customer Relationship Management Solutions • Service Partitioning • Implementations • Next Steps

  4. What does ADS enable? Building block for the creation of service offerings where shifting the roles and responsibilities for service reporting, management and feature expansion from the Network Service Provider to Customer and the Customer’s customers can be easily achieved.

  5. What is ADS…a DNS, LDAP and X.500 directory Root Users Machines Devices Applications Marketing Personnel = Container = Object

  6. What is ADS…a DNS, LDAP and X.500 directory (1) • Domain Naming context rooted on “objectCategory” CN=Domain-DNS,CN=… entry • Schema Class and Attribute definitions require “attributeId” w/ OID value syntax and “lDAPdisplayName” attributes • Information organized hierarchically as objects within Organizational Unit (OU) containers • Every ADS object supports specific or inherited Access Control List security

  7. What is ADS…a DNS, LDAP and X.500 directory (2) • Forest and Tree structure supports representation of large business entity including departments, customers and wholesalers • Within a Tree namespace partitioning can be used to achieve the same levels or heirarchy • Implicit Hierarchical and Transitive trusts lowers initial configuration overhead • Inter - Forest trusts allow for mergers and eCommerce relationships to be defined

  8. …a Relational Database • RDMS that is useful anytime easy to manage, efficient distributed presence is required • RDMS optimized for • Distributed, Replicated, Delegated Admin • Sparse objects • Lots of index creation and rebuild in support of queries • Reuse of record and field definitions in other tables • Data sets are assumed to not change rapidly • Not a replacement for traditional RDMS services • i.e. financials/billing/accounting/subscriber Mgmt • existing databases can be primary that populates ADS when changes occur or reverse

  9. ….a Front End Processor • Authentication • RADIUS (PAP, CHAP, MsCHAP) / LDAP SASL / SmartCards [Certs] / Kerberos / NTLM / HTTP / SMTP / NNTP • Exchange adds POP3 / IMAP4 auth support • Any client (i.e. SecureId) that can do these protocols • Single sign-on dependant on client auth caching support • Query • LDAP / ADSI / OLEDB / … • Any client device that can do these protocols • Custom - Add new FEP protocol services

  10. Microsoft Active Directory • Windows Clients • Mgmt profile • Network info • Policy • Windows Servers • Mgmt profile • Network info • Services • Printers • File shares • Policy • Windows Users • Account info • Privileges • Profiles • Policy • Other • Directories • White pages • E-Commerce • Network Devices • Configuration • QoS policy • Security policy • Management • Focal Point For: • Users & resources • Security • Delegation • Policy Active Directory • Other NOS • User registry • Security • Policy • Firewall Services • Configuration • Security Policy • VPN policy • Applications • Server config • Single Sign-On • App-specificdirectory info • Policy • E-Mail Servers • Mailbox info • Address book Internet

  11. Directory Enabled Networking • Microsoft and Cisco / Adhoc Working group • DEN information model specification in ’97 • LDAP schema representation created • Taken over by Distributed Mgmt Task Force ‘98 • http://www.dmtf.org • CIM 2.2 - 2.3 expected to absorb DEN Information model additions…appx. Q1 2000 • IETF working group plans to post LDAP schema implementation post CIM 2.3 • LDAP schema implementation which required flattening and denormalization • aka Policy Based Management (PBM)

  12. What is Policy Based Mgmt? • Policies applied based on service object storage location or security group membership • Hierarchical supporting global down to service level specific policy settings • if (match policyXyz) • then do action1, 2, … • Bottom Up Policy • End Station initiated policy processing • i.e. Dialup, QOS, VPN service request events • Top Down Policy • Provisioned (/Pushed/Polled) policy processing • i.e. static, intermittently chaning service configurations

  13. Logical PBM Architectures 1. Policy Store 1b. Policy “State Machine” Store [optional] 2c. Policy “Change Notification” Server [optional] 2. Policy Server 2b. Policy Server “Gateway” [optional] 3. Service Control CPE, eCommerce, B2B, hosting, messaging, etc. 3. Service Control
