I have the same question 1. Report abuse. Details required :. Cancel Submit. I'm using Win7 SP1. How satisfied are you with this reply? Figure 1 shows this alert. To take the external list offline successfully, the user must click Install , which means that he or she trusts the package, even if the publisher of the package cannot be verified. To understand why this alert appears when an external list is taken offline, you must understand the process of making the external list available offline.
When you take an external list offline, SharePoint generates an Office development tools in Visual Studio ClickOnce package for a client-side solution. Every Office development tools in Visual Studio package should be signed by an Authenticode certificate to specify who published the package. The user installs the package on his or her client by using the Office development tools in Visual Studio Installer and goes through the process of verifying if the package was published by a trusted publisher.
By default, SharePoint does not have a certificate that can be used to sign the package. So, SharePoint generates a self-signed certificate and signs the package with it. Because this is a new self-signed certificate, the client has trusted neither this certificate nor its issuer before, and therefore cannot verify the publisher of the package. Therefore, the Office development tools in Visual Studio Installer prompts the user with the message that the publisher cannot be verified.
To prevent this alert from appearing, you must provide an Authenticode certificate issued by a trusted Certification Authority to SharePoint for signing the Office development tools in Visual Studio ClickOnce package. This topic shows how to provide an Authenticode certificate to SharePoint.
To perform this task, you need administration privileges for each of the front-end Web servers of the farm. The following steps show how to generate two certificates and import them to certificate stores on the front-end Web server farm. Obtain an Authenticode certificate that is issued by a trusted Certification Authority, for example, VeriSign.
For information about how to obtain a certificate for signing, see ClickOnce and Authenticode. The certificate must contain a private cryptographic key so that it can be used for signing.
For this example, the two certificates, ContosoRoot. The certificate contained in ContosoBCS. The certificate contained in ContosoRoot.
