so may be overlooking the specific advice because it seems “too easy”. In particular, there is no need for custom coding in the IdP to do any of the things you are asking about.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">That’s it on the IdP side. There’s literally nothing else to do. No custom programming, no additional SAMLRequests. None of the code you’ve posted is relevant
to your question of “What should the IdP do?” because your question has been answered.

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">As other people have pointed out, nothing the IdP is doing is directly authorization. The IdP is providing information used for authorization, but it doesn’t
do any (and shouldn’t do any) actual authorization itself. The IdP releases the attributes to the SP, and then it is done. The SP is then responsible for receiving and validating these attributes and handing them off to the application. The application then
uses the values of the attributes to determine what authorization the user should have. The only step where granular authorization is actually happening is within the application. The IdP and the SP are simply passing along attributes.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Because you’ve stated you’re writing your own SP, any questions about “how does the SP do this?” are beyond the scope of this list.

<p class="MsoNormal">Hello Paul,<o:p></o:p></p>
<div>
<p class="MsoNormal">I am really very happy that i am getting lot of information from the Shib Users like you, but i do not know why i am not able to get the exact information which i required. I think i got the replies for my query but i could able to understand
properly.<o:p></o:p></p>

<p class="MsoNormal">Here my actual requirement is:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Now i am using shibboleth idp which we own(External Idp) to do authentication. Here i use 'ExternalAuthn' Login handler in handler.xml. Now the authentication is done by checking the credentials(from login.jsp) with our
<b>Server(database)</b><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">- The current requirement is like instead of using our <b>Server
</b>to validate credentials(from login.jsp), i have to link this external idp to <b>
other Server (database).</b><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">That's why i wanted know about authorization for my application, but i could not able to achieve it.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Please consider my request, because i do not have any other source to get my requirement done, If require i will post my entire authentication procedural steps which i have right now in my existing application.<b> </b><o:p></o:p></p>
