10.16. Finding the Linked Attributes

Problem

You want to find attributes that are linked.

Solution

Using a graphical user interface

1. Open LDP.

2. From the menu, select Connection → Connect.

3. For Server, enter the name of a domain controller (or leave blank to do a serverless bind).

4. For Port, enter 389.

5. Click OK.

6. From the menu, select Connection → Bind.

7. Enter credentials of a domain user.

8. Click OK.

9. From the menu, select Browse → Search.

10. For BaseDN, type the Schema container DN (e.g., cn=schema,cn=configuration,dc=rallencorp,dc=com).

11. For Scope, select One Level.

12. To find linked attributes, use the following for Filter:

    (&(objectcategory=attributeSchema)(linkid=*))

13. Click Run.

Using a command-line interface

> dsquery * cn=schema,cn=configuration,<ForestRootDN> -scope onelevel -filter[RETURN]
"(&(objectcategory=attributeSchema)(linkid=*))" -attr cn linkID

Using VBScript

' This code prints out all of the attributes that are linked
' and their corresponding linkID values
set objRootDSE = GetObject("LDAP://RootDSE")
strBase    = "<LDAP://" & objRootDSE.Get("SchemaNamingContext") & ">;"
strFilter  = "(&(objectcategory=attributeSchema)(linkid=*));" 
strAttrs   = "cn,linkid;"
strScope   = "onelevel"

set objConn = CreateObject("ADODB.Connection")
objConn.Provider = "ADsDSOObject"
objConn.Open "Active Directory Provider"
set objRS = objConn.Execute(strBase & strFilter & strAttrs & strScope)
objRS.MoveFirst
while Not objRS.EOF
    Wscript.Echo objRS.Fields(1).Value & " : " & objRS.Fields(0).Value
    objRS.MoveNext
wend
