Querying Active Directory from SQL Server 2005

Question

How can I query Active Directory from SQL Server 2005?

Answer 1

In order to overcome the maximum limit of 1000 records returned at a time from the Active Directory queries, you can use the function which I wrote below.

CREATE FUNCTION [dbo].[tf_GetAllUsersFromActiveDirectory]
()
RETURNS 
     @USERS TABLE 
        (   
              sAMAccountName    VARCHAR(25)             PRIMARY KEY CLUSTERED     
            , givenName VARCHAR(200)
            , SN VARCHAR(200)
            , userAccountControl VARBINARY(8)
            , mail VARCHAR(200)
        )
AS
BEGIN

INSERT INTO @Users
SELECT  sAMAccountName,givenName, sn, userAccountControl,mail FROM OpenQuery(ADSI, ';(&(objectClass=User)(|(sAMAccountName=A*)(sAMAccountName=B*)(sAMAccountName=C*)(sAMAccountName=D*)) );sAMAccountName,givenName, sn, mail,userAccountControl;subtree')
UNION ALL
SELECT  sAMAccountName,givenName, sn, userAccountControl,mail FROM OpenQuery(ADSI, ';(&(objectClass=User)(|(sAMAccountName=E*)(sAMAccountName=F*)(sAMAccountName=G*)(sAMAccountName=H*)) );sAMAccountName,givenName, sn, mail,userAccountControl;subtree')
UNION ALL 
SELECT  sAMAccountName,givenName, sn, userAccountControl,mail FROM OpenQuery(ADSI, ';(&(objectClass=User)(|(sAMAccountName=I*)(sAMAccountName=J*)(sAMAccountName=K*)(sAMAccountName=L*)) );sAMAccountName,givenName, sn, mail,userAccountControl;subtree')
UNION ALL
SELECT  sAMAccountName,givenName, sn, userAccountControl,mail FROM OpenQuery(ADSI, ';(&(objectClass=User)(|(sAMAccountName=M*)(sAMAccountName=N*)(sAMAccountName=O*)(sAMAccountName=P*)) );sAMAccountName,givenName, sn, mail,userAccountControl;subtree')
UNION ALL 
SELECT  sAMAccountName,givenName, sn, userAccountControl,mail FROM OpenQuery(ADSI, ';(&(objectClass=User)(|(sAMAccountName=Q*)(sAMAccountName=R*)(sAMAccountName=S*)(sAMAccountName=T*)) );sAMAccountName,givenName, sn, mail,userAccountControl;subtree')
UNION ALL
SELECT  sAMAccountName,givenName, sn, userAccountControl,mail FROM OpenQuery(ADSI, ';(&(objectClass=User)(|(sAMAccountName=U*)(sAMAccountName=V*)(sAMAccountName=W*)(sAMAccountName=X*)) );sAMAccountName,givenName, sn, mail,userAccountControl;subtree')
UNION ALL 
SELECT  sAMAccountName,givenName, sn, userAccountControl,mail FROM OpenQuery(ADSI, ';(&(objectClass=User)(|(sAMAccountName=Y*)(sAMAccountName=Z*)) );sAMAccountName,givenName, sn, mail,userAccountControl;subtree')

RETURN
END
