Is there a limit in the number of digital signatures?

Posted By:      Posted Date: December 04, 2010    Points: 0   Category :SharePoint

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...

Digital Signatures Verification Error


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

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

Limit number of characters in the view field



I wonder if I can limit number of characters that are being displayed in the view.  For example, one of the columns sometimes has very long description.  I want people to see only 300 characters, and if they want to read more, they have to click on the link to go to details.

Is it possible?

Thank you.

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?



Is there anz [OperationContract] number limit?




I have a WCF I write in Visual Studio 2010 in c#. Everything worked fine till now. Now I add a new [OperationContract] but it does not work. I does not get a result. I started to debug the problem and found taht in my webservice in the "result" variable the result is there. However in my client there is nothing returned. Tried to debug and turned on the debugging but nothing found. Finally I tried to add a new very simple [OperationContract] which just return a string. Nothing... If I add new [OperationContract] to my code they won't return enything. In the return result; code snippet I found that the result virable is correct but nothing returning to the client while all my previously written [OperationContract] works just fine.

Is there any limitation how many [OperationContract] can I write to my WCF program? Is there anybody who found similar problem?

The number of calls to the Changed event for a single update in the data exceeded the maximum limit.


Dear All,

We have hit the big limit of 16 change events per single update.  Is there any way to extend this to say 25, we are not using infinate loops or anything.

Alternatively, is it possible to disable some change events when values are updated?

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.
