queryn an OpenLDAP server with C#.NET

Question

User-1041979202 posted

hello!!

Sorry because I'm Spanish and I don't speak in english very well.

I need autentication my users against an OpenLDAP server with C#.NET. I'm using the namespace System.DirectoryServices to access an OpenLDAP server but it gives me one error: the server is not operational. I don`t know why it tells me that because the path is correct.

 I'm trying to connect with this OpenLDAP server but I can´t.

String Path = "LDAP://name of OpenLdap server,DC=ehu,DC=es";

DirectoryEntry entry = new DirectoryEntry(Path);

DirectorySearcher search = new DirectorySearcher(entry);

search.Filter = "uid=username";

SearchResult result = search.FindOne();

....

I know that this namespace is correct to interact with Active Directory but I need another namespace to interact with an OpenLDAP server?

Thanks!!

Mari.

DirectoryEntry nRoot = new DirectoryEntry("LDAP://your ip/o=xxx,c=xxx");
nRoot.AuthenticationType = AuthenticationTypes.None;
nRoot.Username = "uid=xxx,ou=xxx,o=xxx,c=xx";  //full dn

nRoot.Password = "xxx";

DirectorySearcher nDS = new DirectorySearcher(nRoot);
nDS.SearchScope = SearchScope.Subtree;
nDS.Filter = "objectClass=*";
//nDS.PageSize = 1000;

SearchResult sr = nDS.FindOne();

I have tried it on openldap, and it works

First, thanks for your answer because this subject is very important for me.

I have one question about your solution. When you tell me:

 DirectoryEntry nRoot = new DirectoryEntry("LDAP://your ip/o=xxx,c=xxx");

Is it the Ip of the server OpenLDAP? and o=xxx,c=xxx is the DN base no?

My DN base is in DC=xxx, Dc=xxx.

Thanks.

yes

"LDAP://ldap server ip or url/base dn"

ex: LDAP://111.111.111.11/dc=aaa,dc=bbb

ps:"LDAP" must be upper
