DirectorySearcher.findOne returns null RRS feed

  • User-510697852 posted

    I am using LDAP authentication in my web application.

    I am using following code,

    string domainAndUsername = domain + @"\" + username;
                DirectoryEntry entry = new DirectoryEntry(_strLdapPath, domainAndUsername, pwd);
    
    DirectorySearcher search = new DirectorySearcher(entry);
    
                    search.Filter = "(samaccountname=" + username + ")";
                    search.PropertiesToLoad.Add("cn");
                   SearchResult result = search.FindOne();
    
    

    I am getting reult as null.

    How can I find exact reason why it's returning null.

    Can I log something like result.tostring(); so will know the reason.

    ----

    It's working fine for some users. Returning null for some users. I want to find out why it's returning null.
