<p class=MsoNormal>Hello,<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

<p class=MsoNormal>I am trying to use PAS for a project requiring
authentication.&nbsp; Here are the expectations:<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>

</span></span><![endif]>Should accept a login/pass in the initial
request.&nbsp; 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

</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>

</span></span><![endif]>Given valid credentials, it should authenticate against
a Postgres DB.&nbsp; 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.&nbsp; 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>&nbsp;</o:p></p>

<p class=MsoNormal>What I have done:<o:p></o:p></p>

</span></span><![endif]>Inside the scriptable plug-in container, I have added a

<p class=MsoNormal><o:p>&nbsp;</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.&nbsp; What I get is, after, many seconds, is a Proxy Error
explaining it cannot read from the server.&nbsp; I am fairly sure it is running
the &#8220;challenge&#8221; script.&nbsp; If I remove one of the parameters it
complains that the script expects one argument and is receiving two.&nbsp; I
also referenced a garbage attribute of request to produce an AttributeError.
&nbsp;&nbsp;Something, however is amiss.<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</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.&nbsp; &nbsp;&nbsp;Is there a
how-to or anyone who has worked a scriptable plugin willing to help me a
long?&nbsp; Any sort of a nudge in the right direction would be wonderful.<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</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>&nbsp;</o:p></p>

<p class=MsoNormal>Thanks in advance.<o:p></o:p></p>

<p class=MsoNormal><o:p>&nbsp;</o:p></p>
