使用 C# 在 LDAP 中搜索标题？

Question

I'm trying to search for a user's title in LDAP using C#.

My current search is this, in which I'm trying to search for a Janitor named John Smith:

search.Filter = "(&(objectCategory=person)(objectClass=contact)(|(sn=Smith)(givenname=John)(title=Janitor)))";

It's not working though.

Can anyone point me to where I'm going wrong? I know I've got the sn and givenname portion correct as that part works .. . but the title filter isn't .

Answer 1

That's probably because that Title attribute is really called personalTitle in LDAP.

Try this search filter instead:

search.Filter = "(&(objectCategory=person)(objectClass=contact)(|(sn=Smith)(givenname=John)(personalTitle=Janitor)))";

Answer 2

What LDAP server are you using ?

On CentOs DS, this one works :

search.Filter = "(&(objectClass=person)(sn=Smith)(givenname=John)(title=Janitor))";
