<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am trying to use PAS for a project requiring
authentication. Here are the expectations:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>1)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Should accept a login/pass in the initial
request. In other words, I want to be able to place a login widget on
another page and login from there by passing the credentials in the initial
request.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>2)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>If login/password are not in the initial request, I
want to challenge for credentials at this point.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>3)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Given valid credentials, it should authenticate against
a Postgres DB. If authentication succeeds I would like a user object to
be created and given a local role defined for that folder (the folder that the
acl_users folder resides) and taken to the application. If it fails it
should continue to challenge with appropriate error messages until the user
gives up or enters proper credentials.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>What I have done:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo4'><![if !supportLists]><span
style='mso-list:Ignore'>1)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Added a PAS object (acl_users folder) in the
application’s root folder.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo4'><![if !supportLists]><span
style='mso-list:Ignore'>2)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Inside the acl_users folder I have added a scriptable
plug-in object.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo4'><![if !supportLists]><span
style='mso-list:Ignore'>3)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Inside the scriptable plug-in container, I have added a
Script “challenge”, updated it under the “interfaces” tab and activated it
under the “activate” tab.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo4'><![if !supportLists]><span
style='mso-list:Ignore'>4)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Added request and response to the parameter list of the
“challenge” Script.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo4'><![if !supportLists]><span
style='mso-list:Ignore'>5)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Created a page template called “login.html” in the same
folder.<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo4'><![if !supportLists]><span
style='mso-list:Ignore'>6)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Added this code to the “challenge” script:<o:p></o:p></p>
<p class=MsoListParagraph style='margin-left:1.0in;text-indent:-.25in;
mso-list:l1 level2 lfo4'><![if !supportLists]><span style='mso-list:Ignore'>1.<span
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>response.redirect(getattr(container,
'login.html').absolute_url(), lock=1)<o:p></o:p></p>
<p class=MsoListParagraph style='margin-left:1.0in;text-indent:-.25in;
mso-list:l1 level2 lfo4'><![if !supportLists]><span style='mso-list:Ignore'>2.<span
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>return
True<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l1 level1 lfo4'><![if !supportLists]><span
style='mso-list:Ignore'>7)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Under the “security” tab removed all checks under
“Acquire permission settings?”<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>At this point I expected that browsing to the url of the app
with no credentials would produce the login.html page as an attempt at a
challenge. What I get is, after, many seconds, is a Proxy Error
explaining it cannot read from the server. I am fairly sure it is running
the “challenge” script. If I remove one of the parameters it complains
that the script expects one argument and is receiving two. I also
referenced a garbage attribute of request to produce an AttributeError.
Something, however is amiss.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have stared at the code and pored over the old mailing
list posts but I cannot seem to get any further. Is there a
how-to or anyone who has worked a scriptable plugin willing to help me a
long? Any sort of a nudge in the right direction would be wonderful.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am currently using Zope 2.8.7 and PAS 1.2-final<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks in advance.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Regards,<o:p></o:p></p>
