I believe that indeed, with Apache, it is not possible to require at the same time a valid-user and allow guest access.
I am not such a fan of current Netscape products but in Netscape Enterprise Server you can allow that (i.e. either a non-authentified guest OR a valid user (but no invalid users)).
In production application, I believe Tamino is usually not exposed to end-users. It is served through the application server. And at the level of the application server and its Web interfaces you can have the control on external accesses.
A work-around in your case you would be to setup a ‘pass-through’ servlet for allowing guest access to Tamino. I never tried the official pass-trough servlet provided with Tamino distribution but I guess it should be easy to use it for that purpose.
