Security :: Digital Signature Under MOSS Error - Access Is Denied
Oct 4, 2010
I have asp.net page running under MOSS2007 and there is Access Denied error at signing (signedXml.ComputeSignature()). The code works as normal .net web application but it does not work under MOSS.
I need to validate a digital signature which consists of thumb impression,signature and tokenid which is in pendrive with a columns of a table in sqlserver2008 database. I am using capicom.dll in asp.net 3.5 using c#.
I am new to digital signature. I have a web application developed in asp.net 3.5. In one of the module of this application I am generating pdf file and storing it on the server. The users must be able to choose a pdf file and digitally sign it with a certificate stored locally (either on their machine or in a smartcard). I do not know whether I should pass pdf file to client place to sign it or I should send Certificate object to the server.
I have problem to create digital signature. I created console application and it works there but when I want to run it at server there is exception. It looks like I have problem with reference to the file.
I posted this previously but it ended up in Languages/C# rather than here. I'm not sure if I chose the wrong forum or the admin moved it. I wanted it in here so I'm re-posting it:
I have an APK file (android application archive, same as JAR file format) that I need to determine whether or not is signed, and if so, extract the certificate info.
The JDK provides a command line tool to do this:
jarsigner -verbose -certs -verify file.apk
I'm trying to determine if there's a way using the Security classes to accomplish the same thing in C# code.
I am currently having trouble with verifying the digital signature in a excel file. The digital signature is used to sign the Macro so that it is possible to authenticate and ensure that no one has tamper with the Macro.
Currently, I am able to check that the excel file is digitally signed. However, I can't seem to be able to verify and ensure that the digital signature is authentic. I'm using asp.net 3.5 with vb.net.
In the application a user will upload a PDF file and then upload a personal signature created using a digital pen. How can I embed this signature in the pdf file?
I'm currently working on an ASP.NET app that I inherited. There are a variety of file operations it has to perform and I'm getting and Access denied error when I attempt to create a directory.I've confirmed that the correct account is being impersonated and authenticated by checking WindowsIdentity.GetCurrent I've also confirmed that the account has full control for the parent folder of the directory I'm trying to create.The only think I can think of is that there might be an issue using a domain account rather than a local account. I'm not really 100% solid on how permissions work in this situation.Any ideas on why the account wouldn't have access? Is there any other code I could try to get more details about what is going on?
I am getting "Access Denied" error when I am trying to write a file on my hard drive (C:/.... xmls/test.xml) from a webservice which is also on my local machine.
The folder structure is like this
AdminApp (Web Folder on C drive) - WebServices Folder - TestService.asmx -Xmls Folder - Test.xml
I tried following settings in IIS in my efforts to resolve the issue:
- Set anonynmous access checked with my account name and password under "Account Used for anonymous access" alongwith integrated windows authentication checked. I am a admin on my machine.
- Disabled anonymous access with only integrated windows authentication checked. I have identity impersonate = true set in my web.config.
I'm moving applications from IIS6 to IIS7.5 (win 7 an win server 2008 r2), when 2 applications (with identity impersonate) try to get a file with response.writefile only from a UNC path i'll get "access denied". In IIS6 and Visual Studio Developer Web Server, same code works. I can save file with FilePath.SaveAs and get name and length with FileInfo, but not download. After 2 days of nightmares I have tried to change
Response.WriteFile(filePath)
to
Response.BinaryWrite(File.ReadAllBytes(filePath))
and now work. My question is: can I have a microsoft developer to sacrificate for my avenge?)
Using MS article http://msdn.microsoft.com/en-us/library/ms998317.aspx, I created a web site to develop a forms authentication solution for our web app. The server is Win 2003 w/IIS 6 and the app is VB.NET. The web.config was updated for forms authentication and settingsappear below:
I am creating virtual directory from my C# code when i execute this code working every finely.
But problem is when i publish this code and access through iis it is showing an error as access denied .
i tried to give permissions to the folder in c:\inetpub\wwwrootfoldername Network service and users provided permissions of full control But still showing an error of Access Denied(mine is iis 5.0 in xp)
Does anyone have any experience with importing meta data files from Ping Identity into an ACS provider?
I'm logged into my Ping Identity admin system, all fine, no problem. Then, when I export the idP file... no digital signature is included within it and thus I cannot import this file into ACS as it complains that there's no signature included.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
We are building an intranet portal not built on Microsoft SharePoint (MOSS) but on DotNetNuke 5.6.1. However, one of the pieces of functionality that is desired is the ability for staff members to view corporate calendars, their inbox, contact lists and Global Address list on the site. The backend for this data is Microsoft Exchange Server 2007. There are some web parts that come with MOSS 2007 that provide this sort of functionality, or at least appear to based on their names: "My Inbox", "My Calendars", "My Contacts", etc. I have been looking for some equivalent third party controls and have not been able to find anything. Does anyone know of anything out here that would suit our needs?
I trying dotnetzip on localhost everything works fine.but on a real dotnet hosting it raises error :
Access to the path 'C:inetpubvhostslahblah.comsubdomains aporhttpdocsDotNetZip-luqevaxu.tmp' is denied. using (ZipFile zip = new ZipFile(Server.MapPath("~")+"/a.zip")) { zip.AddFile(Server.MapPath("~")+"/deneme.txt"); zip.Save(); }
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 am getting this message is one of my subdomains. This was running fine before.
The web application you are attempting to access on this web server is currently unavailable. Please hit the "Refresh" button in your web browser to retry your request.
Administrator Note: An error message detailing the cause of this specific request failure can be found in the application event log of the web server. Please review this log entry to discover what caused this error to occur.
When I tried to look in the event log I found this error.

The site is running on the asp.net 2.0. The parent site is running fine including other subdomains. It is only this subdomain that is having problem and I think I have all the necessary permissions.
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.
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'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.
