Hi All,

I'm trying to connect active directory to asp.net web application made in C# using Visual Web Developer.I'm not sure whether i'm going on the righ track, since its my new research on Active directory connection, please check my code. i'm trying to establish connection to active directory and get the user details.....please recorrect me if i'm wrong.. The code i used to connect to the LDAP is ass below(it says bad url......)

 DirectoryEntry rootEntry = new DirectoryEntry();
            rootEntry .Path ="ldap://000.000.000.00:000/CN=Users,OU=Role-Based,OU=North America,DC=ca,DC=com";
            rootEntry .Username ="DN=CN=GetPaid,OU=Role-Based,OU=North America,DC=ca,DC=com";
            rootEntry.Password ="aaaaaaaa";
           
            DirectorySearcher search = new DirectorySearcher(rootEntry);
           search .SearchRoot =rootEntry ;
            string username="abcdef";
            //searcher .Filter ="(&(objectClass=user) (cn=" + UserName +"))";
            search.Filter = "(SAMAccountName=" + username + ")";
            search.PropertiesToLoad.Add("cn");
            SearchResult result = search.FindOne();
            if(result ==null)
                Response.Write("false");
            else
                Response.Write("true");

 ldap://000.000.000.00:000/
this needs to be the IP address and port of your domain controller.

thanks for your quick reply .....i tried inserting the 141.202.551.21:389  but still it says

Exception Details: System.Runtime.InteropServices.COMException: Unknown error (0x80005000)

Source Error:

Line 73:             search.Filter = ("SAMAccountName=" + "gansa04 ");
Line 74:             search.PropertiesToLoad.Add("cn");
Line 75:             SearchResult result = search.FindOne();
Line 76:             Response.Write(result.ToString());
Line 77:             //String strValue=result.Properties("cn")

I'm sorry I don't have much experience with C# and LDAP I just know about LDAP connection strings.

Sorry

Andy 

Can anyone else help me.......thanks!

Your username must be in the form <domain>\<username> when you specify it with a DirectoryEntry.

Have you tried LDAP:\\ rather than ldap:\\?

Try changing this line

 search.Filter = "(sAMAccountName=gansa04)";

That is how I set my search filter and it works..
