Server Error in '/AnyViewIDS' Application. Config Error. Required Permissions cannot be acquired

5 August 2005

Issue Description

Applies to AnyView IDS 5.2.0.4 and earlier.

 

The AnyView IDS web application is installed on a Windows 2003 server with Windows SharePoint Services (WSS).  When trying to access the web application from the server, the following error is displayed:

Server Error in '/AnyViewIDS' Application.

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Required permissions cannot be acquired.

Source Error: 

[No relevant source lines]


Source File: machine.config    Line: 258

 

This error occurs because Windows Sharepoint Services configures a very restrictive trust policy that applies to all ASP.NET web applications, and does not allow them to run correctly.  The problem is resolved by:

 

1)      Modifying the AnyView IDS web.config file.

2)      Excluding AnyView IDS from SharePoint Services managed paths.

 

Solution

To allow the AnyView IDS (5.2.0.4 and earlier) web application to operate on a server with Windows SharePoint Services installed the following modifications must be made:

 

1) The <trust>, <httpModules> and <pages> sections in the AnyView IDS web.config must be uncommented.  To do this:

 

a)      Locate the AnyView IDS web.config.  In a typical installation this is installed to:

            C:\Program Files\Accountable Software Inc\AnyView IDS\Web Application\Web.config.

 

b)      Open the Web.config with Notepad.

c)       Locate the section of the Web.config shown below and per the instructions uncomment the <trust>, <httpModules>, and <pages> sections.

<!-- WINDOWS SHAREPOINT SERVICES SUPPORT

To allow an AnyView web application to operate on a server with WSS installed:

      1. Uncomment the following <trust>, <httpModules>, and <pages> sections.

 

Set the trust to Full. WSS configures a very restrictive trust policy that does not allow ASP.NET Web application to run correctly.

 

Enable the session module. If you receive the following message:

Parser Error Message: The module 'Session' is already in the application and cannot be added again. You can remove the following <httpModules></httpModules> section as session is already enabled on the virtual server.

 

Enable session state for all the pages in the Web application.

                     

2. Exclude the AnyView web application URL from WSS managed paths by using the Sharepoint Administration Application.

      -->

    <!--

      <trust level="Full" originUrl="" />

      <httpModules>

      <add name="Session" type="System.Web.SessionState.SessionStateModule"/>

      </httpModules>

      <pages enableSessionState="true" enableViewState="true" enableViewStateMac="true" validateRequest="false" />

-->

 

d)      Select File > Save to save the changes.

 

2) If Windows SharePoint Services is installed on the Default web site, it will attempt to control access to or the settings of, all URLs directed to the Default web site.

If the AnyView IDS URL is on a web site that is managed by SharePoint Services, the "Exclude Managed Paths" functionality of the SharePoint Services Administration tool must be used to exclude the AnyView IDS URL from SharePoint management.  

a)      Exclude AnyView IDS from Managed Paths in WSS

Please consult the Microsoft Windows SharePoint Services Administrator guide for instructions on how to use the "Exclude Managed Paths" functionality.  The following steps are only intended to serve as a guide:

    1. Open "SharePoint Central Administration" (Start -> Administrative tools -> Sharepoint Central Administration).
    2. Select Configure Virtual Server Settings -> Default Web Site.
    3. From the "Virtual Server management" section select "Define Managed Paths".
    4. Add a new path and enter "/AnyviewIDS" - Type = Excluded path.
    5. Click OK
