HOWTO : query LDAP with ASP (not an AD)

Hi,

I'm looking for an example of how to read value in a LDAP server. I've googled but always found example based on AD.

Does anyone got such example ?

Thx

with ADO you should be able to do so?
set objADsPath as needed
Set con = Server.CreateObject("ADODB.Connection")
con.provider ="ADsDSOObject"
con.open "Active Directory Provider"
Set Com = CreateObject("ADODB.Command")
Set Com.ActiveConnection = con
Com.CommandText ="select  ... from 'GC://"+objADsPath+"' WHERE ... "
Set rs = Com.Execute

While Not rs.EOF 
  ...
  rs.MoveNext
wend

rs.Close
con.Close
Set rs = Nothing
Set con = Nothing

It's based on AD not ldap

AD is a directory service provider, LDAP is a protocol used to query AD and other directory service providers. The LDAP query in the article i referenced will work with AD, or any other provider - it is not an AD specific query.

ok, I think then you need to get the LDAPClient objects (http://download.cnet.com/ActiveX-LDAP-Client/3000-2206_4-10019353.html),  and :
Set pLDAP = CreateObject("LDAPClient.3")
Call pLDAP.Connect("ldapserver","389","cn=Directory Manager", "password")

Set pAttributeNames = CreateObject("LDAPClient.StringCollection")
Call pAttributeNames.Add("givenName")

' Find all the Johns and all the Smiths
Set pEntries = pLDAP.Search("o=airus", "(|(givenName=John)(sn=Smith))", , pAttributeNames)
For Each pEntry In pEntries
    Response.Write(pEntry.Attributes("givenName").Values(0).Value & "<br>")
Next 

Open in new window

hope this helps

So based on your comments, I've written this :
	Set conn = Server.CreateObject("ADODB.Connection")
	conn.provider ="ADsDSOObject"
	conn.open "Active Directory Provider"
	Set objCmd = CreateObject("ADODB.Command")
	objCmd.ActiveConnection = conn
	objCmd.Properties("SearchScope") = 2
	objCmd.Properties("Page Size") = 20

	objCmd.CommandText = "select cn,mail,sn from 'LDAP://" & ldapIp & "/" & ldapDn & "'"
	response.write objCmd.commandtext & "<br>"
	Set rs = objCmd.Execute

	While Not rs.EOF 
	  response.write rs.Fields("sn")
	  response.write (".")
	  rs.MoveNext
	wend

Open in new window


It seems that the query return something as "response.write (".")" print many points on screen. But I can't get any values

that would be the case if rs.Fields("sn") is returning empty/null all the time ...
you may use another field name instead of sn to get some data...

Ok finally I did it.

You put me on the way. In fact, datas read in the SQL statement are presented as Array. So we can't just read the value. We have to go throw the array as for example :

myValue = rs.Fields("cn")
if isArray(myValue) then response.write myValue(0)
