public string CreateAuthenticationToken(string strEncryptedUserName,
string strEncryptedPassword)
    {
        //Microsoft.Web.Services3.Security.Tokens.UsernameToken
userToken = new
Microsoft.Web.Services3.Security.Tokens.UsernameToken(strEncryptedUserName,
strEncryptedPassword, PasswordOption.SendHashed);
        UsernameToken objUserToken = new UsernameToken("admin",
"admin");
        Security security = null;

        try
        {
          *****************I am getting on this line, Don't why
            int strAuthToekn = security.Tokens.Add(objUserToken);
        }
        catch (Exception strException)
        {
            throw (strException);
            return strException.Message;
        }
    }

you set security to null 1 line higher... you can't call a property of
security if it's null...

I hope it helps
