3. Overview of Active Directory
Directory service provided with Win2K
Hierarchical organization of objects
Domains
Domain trees and forests
Organizational units (OU)
User and computer accounts
Groups (security and distribution)
Resources (contacts, printers, shares)
Use AD tools to manage
AD Domains and Trusts
AD Users and Computers
Highly evolved replication

4. Active Directory Interfaces
LDAP (Lightweight Directory Access Protocol)
Connection protocol between client and server
Provides query and search capabilities
Programmatic interface via C, C++
ADSI (Active Directory Services Interface)
COM interface to AD
OLE DB provider for AD (ADsDSOObject)
Uses LDAP as connection protocol
Provides mechanism for integration with SQL2K

5. SQL2K-AD-E2K Integration
ADSI Query Dialects
LDAP
Binds to an AD location to query against
Specifies filtering criteria
Lists AD properties to return
<LDAP://OU=Directors,OU=Atlanta,OU=Intellinet,DC=vizability, DC=intellinet,DC=com>;(objectClass=User);Name,Title;subtree
SQL
SELECT list provides AD properties to return
FROM clause provides AD location to query against
WHERE clause allows filtering
select Name, Title
from ‘LDAP://OU=Directors,OU=Atlanta,OU=Intellinet,…’
where objectClass = ‘User’

6. SQL2K-AD-E2K Integration
ADSI Schema
IADsUser (objectClass=User)
Not all IADsUser properties are available via LDAP
Use AD property names, not ADSI property names
IADsGroup (objectClass=Group)
Very few properties are actually available
Cannot query for array-based properties
Group members for example
Dig into the ADSI SDK for information

7. SQL2K-AD-E2K Integration
Querying AD from SQL2K
Create a linked server using ADsDSOObject
exec sp_addlinkedserver 'ADSI', 'Active Directory Services 2.5',
'ADsDSOObject', 'adsdatasource‘
Execute LDAP queries via openquery()
select convert(varchar(30), [Name]) as FullName,
convert(varchar(30), Title) as Title
from openquery(ADSI,
'<LDAP://OU=Directors,OU=Atlanta,OU=Intellinet,…>;
(objectClass=User);Name,Title;subtree')
convert(varchar(30), Title) as Title,
'select Name, Title
from ''LDAP://OU=Directors,OU=Atlanta,OU=Intellinet,…''
where objectClass = ''User''')

8. SQL2K-AD-E2K Integration
Overview of Exchange 2000
Next generation messaging system
Win2K integration
Integrates with AD for directory services
Message transport via Win2K services (IIS, DNS)
Web Storage System
Provides HTTP, WebDAV, and XML access
Supports multiple databases for mail and folders
Real-time collaboration
Programmatic interfaces
CDO, CDOEXM, and ADO
OLE DB Provider for Exchange (ExOLEDB)

9. SQL2K-AD-E2K Integration
Content Classes in E2K
Every resource belongs to a content class
urn:content-classes:message
urn:content-classes:person
urn:content-classes:appointment
Each content class has a set of properties
urn:schemas:mailheader:subject
urn:schemas:contact:sn
urn:schemas:calendar:dtstart
Custom content classes can be defined

10. SQL2K-AD-E2K Integration
Namespaces in E2K
Namespaces provides unique names for every property in the Web Storage System
Allows properties with the same name to be distinguished (for example, the “From” property)
A namespace includes various properties and may be used by different types of resources
DAV:
urn:schemas:httpmail
urn:schemas:contacts
urn:schemas:calendar
ExOLEDB adds “file:\\.\backofficestorage” and “ namespaces

11. SQL2K-AD-E2K Integration
SQL Dialect for E2K
Uses syntax similar to SQL2K with Full Text Indexing options included
select <list>
from scope(<scope1>, <scope2>, …)
where <condition>
order by <list>
group by <list>
rank by <list>
“Select” clause specifies the properties to return, using namespace notation
“From” specifies the scope and path to search
Scope specifies the depth of the search
Path specifies the URL to search

12. SQL2K-AD-E2K Integration
SQL Dialect for E2K
“Where” clause specifies the filtering condition
Can use any of the following predicates, functions, and clauses
cast, contains, formsof, freetext, like, rank by
Conditions connected via “and” and “or”
“Group by” and Order by used as in SQL2K
“Rank by” allows for ranked results
select “DAV:displayname”
from scope(‘shallow traversal of “
where “DAV:isfolder” = TRUE
order by “DAV:displayname”

13. SQL2K-AD-E2K Integration
Querying E2K from SQL2K
Create a linked server using ExOLEDB
exec sp_addlinkedserver ‘E2K_PF', 'Exchange OLE DB provider',
‘ExOLEDB.DataSource.1', 'file:\\.\backofficestorage\
vizability.intellinet.com\public folders‘
Use openquery() to execute queries
select convert(varchar(30), "urn:schemas:contacts:sn")
as LastName,
convert(varchar(30), "urn:schemas:contacts:givenName")
as FirstName
from openquery(E2K_PF,
‘select "urn:schemas:contacts:sn",
"urn:schemas:contacts:givenName"
from scope(''shallow traversal of
".\Intellinet\Atlanta\Atlanta Contacts"'')')
