How to Get the Canonical/Distinguished Name of a OU

Question

User-456111751 posted

Hi All,

I need your help in getting the CN/DN if the last part of the OU name is provided. For ex In our Active Directory domain of xyz.org which has OU of Accounts, sub OU Users and another Sub OU Managers  (xyz.org>Accounts>Users>Managers)

Here If I provide Managers as an Input, it has to output the CN:

xyz.org/Accounts/Users/Managers

Something like below:

        DirectoryEntry dirEntry = new DirectoryEntry("LDAP://xyz.org");
        DirectorySearcher ds = new DirectorySearcher(dirEntry);
        string objectName = "Managers";
        ds.Filter = "(&(objectClass=organizationalUnit)(OUName(Notacorrect)=" + objectName + "))";
       
    try
        {
            if (ds.FindOne() != null)
            {
                //Get the DN or CN name as said
            }
        }
catch
{

}

 

Please help

        ds.PropertiesToLoad.Add("cn");
        ds.Filter = "(&(objectClass=organizationalUnit)(ou=" + objectName + "))";
        
        if (ds.FindOne() != null)
        {
            SearchResult deResult = ds.FindOne();
            string ouName = deResult.Properties["cn"][0].ToString();
        }

Try this,

   

DirectoryEntry dirEntry = new DirectoryEntry("LDAP://xyz.org");

 DirectorySearcher ds = new DirectorySearcher(dirEntry); 

ds.SearchScope = SearchScope.Subtree;

 string objectName = "Managers"; 

ds.PropertiesToLoad.Add("canonicalname");

 ds.Filter = "(&(objectClass=organizationalUnit)(name=" + objectName + "))"; 

if (ds.FindOne() != null) { SearchResult deResult = ds.FindOne(); string ouName = deResult.Properties["canonicalname"][0].ToString(); }

Index was out of range on string ouName = deResult.Properties["cn"][0].ToString();

Index was out of range most likely means that the value is not indexed, and need to be requested as

string ouName = deResult.Properties["cn"].ToString();
