We want to show a error message for the password authentication en main page without redirecting to the “Names.nsf?Login” form, i mean, we need the error message to be shown in the same main page.

that’s how session authentication works.
you can modify the look and feel of it via the domcfg.nsf

but the url will always be names,nsf?login
you could consider using basic auth instead but more limited in your login prompt options
or off-load authentication somewhere else via SAML, DSAPI filter, or some other websso solution (like webseal)
