This happens on my home installation on the latest MAIN branch (and on previous TWikiRelease04x00 branch). I have not changed anything on my setup recently, but as a authenticated user I am identified as TWikiGuest in TWiki since the end of Sep 2006.

I am using basic authentication on all files in twiki/bin, content of twiki/bin/.htaccss:

Order Allow,Deny
Allow from all
SetHandler cgi-script
AuthUserFile /path/to/twiki/data/.htpasswd
AuthName 'Enter your WikiName: (First name and last name, no space, no dots, capitalized, e.g. JohnSmith). Cancel to register if you do not have one.'
AuthType Basic
ErrorDocument 401 /error.html
Options -Indexes
<FilesMatch "configure.*">
       require user "PeterThoeny"
</FilesMatch>
<FilesMatch ".*">
       require valid-user
</FilesMatch>

Basic auth is working properly (I am asked to login)

Relevant LocalSite.cfg settings:

$TWiki::cfg{UseClientSessions} = 0;
$TWiki::cfg{Sessions}{Dir} = '/tmp';
$TWiki::cfg{Sessions}{ExpireAfter} = 21600;
$TWiki::cfg{Sessions}{IDsInURLs} = 0;
$TWiki::cfg{Sessions}{UseIPMatching} = 1;
$TWiki::cfg{Sessions}{MapIP2SID} = 0;
$TWiki::cfg{LoginManager} = 'none';http://develop.twiki.org/~twiki4/cgi-bin/view/Sandbox/JSCalendarTest?skin=classic

$TWiki::cfg{DefaultUserLogin} = 'guest';
$TWiki::cfg{DefaultUserWikiName} = 'TWikiGuest';
$TWiki::cfg{AuthScripts} = 'attach,edit,manage,rename,save,upload,viewauth,rdiffauth';
$TWiki::cfg{AuthRealm} = 'Enter your TWiki.LoginName. (Typically First name and last name, no space, no dots, capitalized, e.g. !JohnSmith, unless you chose otherwise). Visit TWiki.TWikiRegistration if you do not have one.';
$TWiki::cfg{PasswordManager} = 'TWiki::Users::HtPasswdUser';
$TWiki::cfg{MinPasswordLength} = 1;
$TWiki::cfg{Htpasswd}{FileName} = '/path/to/twiki/data/.htpasswd';
$TWiki::cfg{Htpasswd}{Encoding} = 'crypt';
$TWiki::cfg{UserMappingManager} = 'TWiki::Users::TWikiUserMapping';
$TWiki::cfg{LeaseLength} = 3600;
$TWiki::cfg{LeaseLengthLessForceful} = 3600;
$TWiki::cfg{MapUserToWikiName} = 1;

A Cairo installation pointing to the same data works as expected.

You have not set a login manager, so TWiki doesn't know how to obtain a username for you.

Set the login manager to ApacheLogin. 'none' means you are not using any logins.

Please discard this report when you are happy that it works as documented. Thanks.

Yep, that was it, thanks.

I did not change anything in configure recently, meaning that authenticated users in 4.0.2 used to be identified even with login manager set to 'none'; but not anymore with the latest TWiki. (In fact, I have another working 4.0.2 installations with identical setup and login manager set to 'none'.)
