[Zope] strange login behaviour

[Didier Georgieff]

Hello,

I have really simple login wich is a link to a Method "login" wich 
comprise

...... REDIRECT for login
<dtml-call "RESPONSE.redirect(baseURL)">

and 'login' method has NO autorizations for anonymous.

It redirects me on the right "baseURL" page, but the "baseURL" 
inludes an "info" Document with 

<dtml-var "AUTHENTICATED_USER.getUserName()">
<dtml-in "AUTHENTICATED_USER.getRoles()">

who shows ONLY anonymous after the first login..

IF I do a second login (exactly the same) then it works fine and i 
got the right Names and Roles..

Is it a known problem, or do i have some magic acquisition trick 
who eludes me ?

I'm on 2.1.6 win.
