Security :: Custom Access Denied Page For Role Based Security?
Oct 27, 2010
I have implemented role based security in my asp.net 2.0 vb.net application using windows authentication and the windowstokenroleprovider and limiting access to certain pages using the location tag to specific active directory groups.
The issue is that when a user tries to access a page they are not authorized to view it brings up a login prompt and when it does not pass it takes them to the default page that tells them they are not authorized to view the page. I am wondering if there is a way to throw up a custom page that tells them they are not athorized to view the page that I can incorporate into the site itself with the header and so forth? if this page could come up in lieu of the sign in box popping up as well.

I'm not sure if this is possible or not, I'm using Roles to limit what pages a user can access based on there assigned Role. My question, is there anyway to redirect the user to a specific web page based on thier role after they login.
For example:
If Bob logs in with Role="Automotive", I want him to be redirected to Auto.aspx.If sue logs in with Role="Clothing", i want her to be redirected to cloths.aspx.

I'm workng on a new, green-field ASP.Net application. We're implementing a base page which all pages will be, er, based on. The application will be running under Integrate Windows Auth, so I'll have the user's account details. With these, I'll be going to several databases (in which the user will exist) to find out what roles they are assigned to in each db. I'll be holding the role yay/nay in a bool array, and key into it via an enum.
There will be a session object that will hold a few things, and the roles assigned for that user. I'm thinking of making the session object available as a property of the base page, as the code would be something like this:
public SessionObject MasterSessionObject
{
get
{[CODE]....
But, I'm sure you'll agree, it looks sucky...If there was a CheckSecurity method on the base page, it would have to take a concrete DatabaseRoles object, but also an enum of which role to check, which would also look sucky. And finally, there would be a requirement at a later date to add more databases and their security settings...
I'll add code tomorrow if required... :-s
I dunno, I'm not that thick, but I do have a hard time sometimes binding all this together...

Usually in sub-folder we will limit the access right to some roles and this feature requires pre-defined database schema.
However, if i still want to use this role feature of asp.net, but I do not like the pre-define database schema, I want to extract role information from my own database table and bind it to the role.

I have a web app developed using role & membership provider...
this is my web.config file
<authentication mode="Forms">

[ASP.NET 3.5, FormsAuthentication, SQL Server]
In the Roles table there is Role, and RoleType.
I have 3different roles, 2 of which have sub-roles.
Example
Role----------------------Type
Adminstrator
Subscriber---Basic
Subscriber---Business
I need to implement Code Access Security, and URL based security using the roles & types...
For instance, the (Subscriber/Basic) would need to view a different set of pages, and have different access to things then a (Subscriber/Business).
I think I can handle the Code Access security with a custom attribute, but I am unsure to how enforce a User be apart of 2 roles in the URL Authorization.
I am currently using the web.config to deny/allow access to the directories/pages.
e.g.
/Areas/Admin/web.config
[Code]....
Is it possible to force the user to be apart of 2 roles with this technique?

<ul>
<li><a href="#">Services</a></li>
<li><a href="#">About us</a></li>
<li><a href="#">Admin</a></li>
</ul>

I am building an ASP.NET 3.5 Web Application and I am NOT using the membership provider for security. In the application I have a role named Admin and all the files for this role are inside the Security folder in the project. Currently for all the pages inside the security folder I am checking to see if the logged in user's role is an Admin or not. This to me seems very redundant, can do something like "If the user is requesting a page inside the security folder then check his role".

I have the following web.config file in my MemberPages directory:
<configuration>
<system.web>
<authorization>
<allow roles="member" />
<deny users="*" />
</authorization>
</system.web>
</configuration>
If the User is a "member", he/she is allowed access to web pages in the MemberPages directory. Otherwise, he/she is denied access. The mechanism works. However, when the User is denied access, the following very unfriendly message appears:
Server Error in '/MyWebSite' Application.
The resource cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its dependencies)could have been removed, had its name changed, or is temporarily unavailable. the following URL and make sure that it is spelled correctly.
Requested URL: /MyWebSite/MemberPages/member_page.aspx
How can I redirect the User to a more friendly page if he/she is denied access?

I am new to IIS and have some questions.
I've put my application on IIS with a App Pool I newly created. The App pool setting is integrated and networkservice.
My application reads a local file from a local machine. When it tries to do that, I receive an exception saying that "Access to the path c:..xxx is denied". Isn't the app using the credentials logged into the local machine?!
doesn't "integrated and networkservices" mean.. use the credentials logged in to windows?

I want to know how can i redirect a user to a different page when he tries to access a page restricted to another role?
The scenario is as follows:
I have a folder "Gestao" that only allows users in role "Administrator"
[Code]....
If an anonymous user tries to access that folder he is redirected to the login page, but if a logged in user whose role is "friend" tries to access this folder he is also redirected to the login page. I want to redirect him to a page showing a message that he has no permission to access that page/area.
How can I do that? Should i have code on the Page_load event of the login page checking the user role and then redirect him to the correct page? Or is there some otherway to do this?

I have an asp.net application. This is a role based authorization. Basically, if the user's are in a specific AD group, it should allow them to look at the webpage. Otherwise it should error out saying "not authorized".
In the web.config file, I have the following lines of code. I made sure I am in the Apr-Sales-Writers AD group.
Code:
<authorization>
<allow roles="Apr-Sales-Writers"/>
<deny users="*"/>
</authorization>
Issue: when I go to default.aspx page, it prompts for a userid and password and even though I put correct password and userid, it says "not authorized error".
Code:
Access is denied.
Description: An error occurred while accessing the resources required to serve this request. The server may not be configured for access to the requested URL.
Error message 401.2.: Unauthorized: Logon failed due to server configuration. Verify that you have permission to view this directory or page based on the credentials you supplied and the authentication methods enabled on the Web server. Contact the Web server's administrator for additional assistance.
In the IIS project (on IIS server), I configured it to be a "Integrated windows authentication".

I'm a lowly DBA.I am supporting a web app that allows users to upload images (among other documents). The system is deployed and working and not having issues with the uploads. However, I upgraded my development box recently and since then I have been encountering an "access denied" issue. Initially I thought it was a simple security issue but now it seems it is more complex.

I have set up a simple bit of code to upload an image to the web server. It works offline without a hitch but online I get an error saying denied access.I am not overly surprised to be honest as I have not configured anything on the server (through my web host "Mochahost") to allow unknown users to upload files. I wonder if someone could point me in the right direction.

I have read this post [URL] about something similar to my problem, but here is the thing, this Web Application worked without problems until someone changed some rights in the folder: '\ServerNameFolder' I have write permissions for both "DOMAINusername" and ASPNET but it doesn't work, anytime I attempt to upload a file from theweb app the "access to the path '\ServerNameFolderTest.xls' is denied" appears. But if I do it
manually with "DOMAINusername" it works.

In my asp.net website in VS-2005 with SQL-Server 2005 as db, I need to implement role-based Authentication/Authorization.
I am familiar to the practises used in role-based authentication..as I have previously worked on projects that used this method. However, my project lead used to design the database. Now I have an existing website where authentication has been set to anonymous by setting 'allow users="?"' in the authentication tags in web.config.
If I use the createUserWizard control and use the Membership.creatUser(.....) method in code behind will the asp.net security tables, like users, roles, userinrole etc get created on its own?

I am trying to implement a simple role based authorization using forms authentication in ASP.net. It works perfectly fine in my local system but fails when I deploy in production (shared hosting). Whenever I try to log in, rather than taking me to the default page in specified directory it throws me back to the login page. I suspect that there is some issues with the configuration but not sure where the problem is. The code is provided below:
Web.config (root):
[Code]....
Web.config (Member directory):
[Code]....
Login.aspx:
[Code]....
Global.asax:
[Code]....
Works fine in local machine but shared hosting is not taking the authenticated user to the pages inside the secured folders. What can be the issue?
