To develop LDAP group retrieval code to look up the user's group membership

1. Add the following implementation of the GetGroups method to the LdapAuthentication class.

 public string GetGroups()

    DirectorySearcher search = new DirectorySearcher(_path);

    search.Filter = "(cn=" + _filterAttribute + ")";

    search.PropertiesToLoad.Add("memberOf");

    StringBuilder groupNames = new StringBuilder();

    try

    {

   SearchResult result = search.FindOne();

    int propertyCount = result.Properties["memberOf"].Count;

    String dn;

    int equalsIndex, commaIndex;

   for( int propertyCounter = 0; propertyCounter < propertyCount;

       propertyCounter++)

    {

     dn = (String)result.Properties["memberOf"][propertyCounter];

    equalsIndex = dn.IndexOf("=", 1);

     commaIndex = dn.IndexOf(",", 1);

     if (-1 == equalsIndex)

      {

        return null;

      }

     groupNames.Append(dn.Substring((equalsIndex + 1),

                       (commaIndex – equalsIndex) – 1));

     groupNames.Append("|");

    }

  }

 catch(Exception ex)

  {

   throw new Exception("Error obtaining group names. " +

     ex.Message);

  }

  return groupNames.ToString();

}
