Hi,

I’m trying to install “Telerik_AJAX_controls_2010_2_929_for_SharePoint_2010_Dev.msi” and I have a rollback installation failure.

I’m very interested to know why the installer tries to access the "SharePoint_Config" database:

Looking in “event log”:

SQL database login for 'SharePoint_Config' on instance 'SP2010D' failed. Additional error information from SQL Server is included below.

Login failed for user 'PHARMA\GTYSAPPSPTT01$'.

Looking in “installation wizard log”:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Management.Automation.CmdletInvocationException: Cannot access the local farm. Verify that the local farm is properly configured, currently available, and that you have the appropriate permissions to access the database before trying again. ---> Microsoft.SharePoint.PowerShell.SPCmdletException: Cannot access the local farm. Verify that the local farm is properly configured, currently available, and that you have the appropriate permissions to access the database before trying again.

Hi, we have a scenario as follows:

We are using impersonation to send the windows credentials of the logged in user (NOT ASP user) to the file system.

The token is checked and the appropriate folders are displayed for that user.

The root folder is set to allow all users to view the contents of THIS FOLDER ONLY. Permissions are then set via NTFS per folder under the root folder.

SO EVERYONE CAN SEE THE LIST OF FOLDER UNDER THE ROOT FOLDER.

If we have 3 folders under the root folder, I want to list these 3 folders for the user. If they then try to navigate to one of the sub folders, the user’s NTFS permissions are  used to determine if they can enter the folder, and if so, if they can read/write, etc in that folder.

This all works with the radfileexplorer EXCEPT that if a user does not have read or write permissions to one of the sub folders the control first triggers a windows challenge response, then you get an access to path “x” is denied error.

This behaviour is fine, as long as I can TRAP and handle this. I assume I need to override either the  
FileSystemContentProvider.ResolveRootDirectoryAsTree function or
DirectoryLister.GetDirectory function.

I assume the problem is that the file explorer control is reading the root folder, then trying to read the contents of the sub folders in the root. As the user does not have any permissions to this folder, this causes the problem.

The only change I want to make is that it either doesn’t attempt to read sub folders when creating the root (I assume this is done in resolverootdirectoryastree).

If the user then tried to access a folder that they do not have access to, I would like to be able to handle this as well.

I have a much simpler page which has this functionality. When I list the files and fodlers in a direcotyr I simply encapsulate it in a try and catch – this allows me to handle the access is denied error:

Try

            Dim arrFiles As New ArrayList

            arrFiles.AddRange(myDir.GetFiles)

            Dim arrFolders As New ArrayList

            arrFolders.AddRange(myDir.GetDirectories)

        Catch ex As Exception

            Literal1.Text = ("<script language=""javascript"">alert('Error reading path: " & myDir.FullName.Replace(lblRootPath.Text, "[Root Folder]\").Replace("\", "\\") & "\n\n" & ex.Message.Replace(lblRootPath.Text, "[Root Folder]\").Replace("\", "\\").Replace("'", "\'") & "');</script>")

        End Try

The trace for the error is below:
