Digital Signatures Verification Error

Posted By:      Posted Date: August 26, 2010    Points: 0   Category :SharePoint

Hey all;


Not 100% sure this is a sharepoint problem, but maybe someone can help.  I am installing a digital signature block that is being made available on a browser form.  The sig is working, but I can not get a valid signature on the form.  I am told there is a Digital Signatures Verification Error. 


Reading other posts tells me that I have to have my signature cert in the trusted Root authority of the sharepoint server.  Here is the rub..


When I use certificate manager, I s

Digital Signatures: Application Guidelines on Digital Signature Practices for Common Criteria Securi


This article is an overview of digital signature practices and user considerations necessary to write applications in compliance with ISO/IEC 15408 Common Criteria security. Signing categories are described, including those that are a potential risk to the implied trust association that goes with a digital signature.

Can SharePoint read/recognize Digital Signatures?

I am using Content Control Mapping to pull certain fields from a Word Document and include it as columns when a document is uploaded into a Document Library. We're using MOSS 2007 and Word 2007. It is required that the user digitally signs the document before uploading.  Is there a way to get the signature to appear as a column in a similar fashion?  Alternately, even just showing that the document was signed would be nice.  I'm new to this mapping business, and Google hasn't been much help. I realize I could use the Collect Signatures workflow, but that seems cumbersome to 1) have the user submit it, 2) have an admin open each document and start the workflow and 3) have the user THEN sign the document.  That's more steps than simply manually opening and verifying digital signatures. I figure I'm missing something obvious here.  Any help or ideas would be appreciated.

http://blogs.msdn.com/b/raulga/archive/2006/10/30/using-a-digital-signature-as-a-secondary-identity-to-replace-cross-database-ownership-chaining.aspx Greetings. The object names used here reflect the article, though they were of course modified in my environment. So I just completed the above exercise customized for our environment. I skipped the step of creating the sproc in db_source, because it already existed. However, when I would get to this part: ADD SIGNATURE TO [schema_MyApp].[sp_MyApp01] BY CERTIFICATE [cert_MyAppSecIdentity] WITH SIGNATURE = 0x5EF9C30476A8E3E248E9E11B7563528EB02DA1D8F440CAA9141841B9F3101F1988760D2775000CD0D70F44A8672984E327FBF2676E7FAC9AAED8E6F383A98B2A569A407577917E671F3D632EF7326AD3770A32E05CF43A613D310D64B6D52FD978E57A73912BF3587C475E48F4AA58561A7E0DB5D9DB53D35E03EC281BEC7772 go I kept getting the message along the lines of "invalid public key". Of course I changed the sproc name and SIGNATURE according to my environment, so I don't know why there would be an issue? I only got around it when I dropped/ recreate the sproc in db_source, which kind of has me worried. Any ideas?  TIA, ChrisRDBA

Approval Workflow and Digital Signatures


Environment = SharePoint MOSS 2007 Enterprise versio, and Office 2007 Professional/Enterprise

User = SharePoint Collection Admin, Full Control, other users signing and approving have Contribute permission

Settings on Out-of-the-Box (OOB) Approval WF are:  Start manually (no restrictions on manage list permission), Update Approval status on workflow completion, using the Worklfow Tasks list (created by default with the Publish feature enabled)

Documenent library requires content approval and both major and minor versioning are enabled.

Then, in a Word document,  digital signatures are inserted, and the Approval WF is started from within the Word client.  Here is what seems to be odd.  The document is required to be checked out (otherwise the sign operation is not allowed).  Upon checking the document out in order to sign it (no other modifications to the document), the minor version increases...normal behavor for checkout and checkin.  However, in signing a document, we would not want the minor version to change.  Also, the minor version increment is not necessarilly by one.  It might go from 0.1 to 0.3., 0.5., then 0.6 just with one person tasked to sign it and one check out one check in.

Question:  How is the OOB Approval workflow with digital signatures in say Word, really supp

Adding Digital Signatures to repeating sections


I'd like to know if there is someway to accomplish this without going into code behind.

I have tried to put a section into a repeating table but after applying a signature to it the ability to add a new section is lost. I am using a web enabled InfoPath 2007 form.

I selected Allow only one signature and lost the ability to add a new row. The button and text were gone from the reepeating table.

I selected All the signatures are independent (co-sign) and I wasn't able to add a new row to the repeating table. The text and button was there but when cliked got a message reading "This value has been digitally signed and cannot be changed"

I selected Each signature signs the preceding signature (counter-sign) and had the same effect as the co-sign option.

The app keeps making the controls read-only. I turn it off and it goes back to checked.

Any ideas on how to make this work? Or if it is possible?



SharePoint 2010 Collect Signatures workflow - no digital signatures?


Hello, I configured a "Collect Signatures" workflow for the content type "Document", then uploaded a MS Word 2010 (.docx) document as content type "Document".  This Word document as 2 empty Signature Line in it.

I then start the workflow, basically 2-stage with 2 person from my Active Directory.  However, what I found is that when I go to my workflow task and click on the "This document requires your signature" link, it pops up a "Workflow Task" box in the browser.  There is a "Sign" button which I can click to sign but it does not sign on the signature lines inside my Word document.

What am I doing wrong here?  Or does SharePoint 2010 Collect Signatures workflow no longer work with digital sigantures?  Thanks.

Is there a limit in the number of digital signatures?


Is there a limit to the number of different digital signature lines/sections you can add to a form? They would like 8 different signature lines/sections  for various reasons and on the last few I can't seem to add any more. They all wind up using the same digital signature data to sign, if i change one they all change..

Thanks for any help...


IsapiModule Error 500 Issue


I am about exhausted trying to figure out this error:

HTTP Error 500.0 - Internal Server Error

Description: The page cannot be displayed because an internal server error has occurred.

Error Code: 0x8007007b

Notification: ExecuteRequestHandler

Module: IsapiModule

Requested URL: http://localhost:80/ReportServer

When I enable Failed Request Tracing Rules and view the log output I am supposing that the actual problem is in the 2nd call where there are 2 backslashes before the actual filename in the specified path:

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

Jscript error: Object does not support property or method


 Hi, i have little knowledge on javascript but i need to use this code get from somewhere for a jquery to work.

I face this "Jscript runtime error: Object does not support property or method" whenever im trying to run this page.

In my experience, im get this error msg 9 out of 10 times i use javascript in my system.

Im using Microsoft Visual web developer 2008, i wonder if this is related to my problem, i not sure there is anything i need to add as reference or update anything.

But anyway, in short, i just couldn't use javascript code when using this development tool because of this sort of error.

Anyway, it happen that last time i tried use the same type of jquery code in another project and it seems to work well without an error.

But now when im try to use it again in this recent project i created, it come out with this error and i have no idea how to solve it even look through google and this forum.

It doesn't really seems like its the code problem itself although im not sure, because any javascript code just couldn't work.

So below is my code that i need to use.

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" ></script>
<script type="text/javascript" src=&quo

Type or namespace error.


A couple of days ago I started getting an unusual behavior when compiling Website projects. I have referenced class libraries added to my bin folder that are also correctely referenced in using statements in my aspx.cs code behind. When I compile, I get the

error message that would typically be received when the dll has not been added as a reference or added in a using statement.

I can eliminate the error by adding an


HTTP Error 403 - Forbidden


(VB Express website directed me to ASP.NET Web Services which in turn redirected me to this forum).

 Hopefully someone can help me here...... 

I am using VIsual Web Developer and downloaded the small business application to use as a starting point to help my wife get a website up for her small business. When I load the application, I can F5 and it runs fine but as soon as I make any modification to the app and hit F5, I get the HTTP Error 403 - Forbidden when it tries to show the website.

I notice a pop up that occurs when I run that allows me to choose the link for my app and it displays correctly (I close the webpage that has the error on it).

This seems like a pain, is there a setting I'm missing - I would think that this should "just work".

What's up?????

Insert Error not helpful



I am using VS2010

When I try to updated or insert a record in my User table I am getting an error that does not make sense to me and I cannot figure out what is wrong.

Also, when I try to insert a new record I get a validation error saying that the Id is required. However it is an identity field in the db so it should not be necessary to send it to the server.

Could you please shed some light?

Server Error in '/' Application.

Value of member 'ID' of an object of type 'Ref' changed.
A member defining the identity of the object cannot be changed.
Consider adding a new object with new identity and deleting the existing one instead.

I get this error whenever I attempt to update an entry. Even an entry that has had nothing altered. I have tried to circumvent it but I think it must be a simple oversight. How could I have caused an ID update using the Edit.aspx page of dynamic data? Thank you in advance for the help!
