I have delete task on Azure Data Factory which I want delete files on VM with FileSystem as Linkedservice.
but i try debug this activity have error and denied permission like this:
FYI, i can delete this file from VM with delete manual with press key del on keyboard. big many thanks to answer my question.
Make sure you have followed Prerequisites and the username and password provided at FileSystem linked service has enough privilege (write permission) to delete the source file. (latest version of self-hosted integration runtime, If the access is restricted to IPs that are approved in the firewall rules, you can add Azure Integration Runtime IPs to the allow list)
You can verify access by using a lookup activity with same source file.
In FileSystem linked service you would have to specify the path to a Folder, i.e. "the root path of the folder or the Azure File Storage endpoint"
e.g. C:\[Folder]
Next in the Dataset you can further specify the relative directory or the File name.

I am having a weird issue that didn't used to happen. Perhaps windows update causes this?
We have an E drive partition created and I created a directory:
Test1
I shared it with administrators and everyone. Administrators have full access while everyone group only has read permissions but this folder only. I added a permission to allow full control to this folder and subfolder's and files to it and assigned it to domain admins. My jadmin#domain.local account is added to this group
I checked the security on the folder and the same permissions exist.
I created a directory within Test1 and called it New Folder, disabled inheritance and made sure explicit permissions for domain admins full control to all dir and subdir and files are added.
When i attempt to open this folder, i get a message:
"You don't currently have permission to access this folder. Click Continue to permanently get access to this folder".
When I Push Continue then an explicit permission for my user gets added to that folder. I am trying to prevent that from happening. If domain admins(my user added to this group) is added with full control. Why does this warning pop up and require my user to explicitly be added. How to prevent this from occurring?
I was expecting to be able to access the new folder directory without any warning and an explicit permission to be added
Check if you can access it with an elevated CMD.
Folders wich are protected for builtin administrators groups are supposed to be security relevant. These users should also not be used to administrate on server systems.
Increase security by creating a seperate admin group and dedicated permissions.
Alternatives are using a progam that can be started elevated, Like CMD, PowerShell, totalCommander, winscp (local part) and many more.
You could also administrate remote. That should remove the problem.
Another way would be to add "Interactive Logon" group to all of your permissions where you need to access.
Disabling UAC or removing administrators from the security settings is the least that I would suggest.
Our application uses a shared directory to store files that are 'checked out', modified via our application, and then 'checked in' to a shared directory, which is being accessed via SMB (The environment is hosted on a set of AWS servers, and our end-users access it via Citrix).
All users have read, write, etc. permissions for the shared directory.
We've recently changed the architecture of the application a bit. Previously, each user had his/her own subdirectory in the shared directory where the checked in/checked out file was stored.
In the new architecture, the individual subdirectories aren't used, so that all files checked in by users are stored directly into the shared directory. Users are then allowed to checkout/checkin any file in the shared directory.
The checkout process involves doing a File.Copy of the library version of the file to the user's local, non-shared directory. The user then uses our application to make changes to the file, which is then saved locally and File.Copy'd back into the shared directory.
Except that in the new architecture, the 'checkout' operation fails when User 2 attempts to checkout a file that was originally checked in by User1. As near as we can tell, this is because when, for example, User 1 checks a file in to the shared directory, the file implicitly receives a security entry for his specific AD login. A subsequent File.Copy operation by User 2 gets a permission error. If a full admin for the host system removes the security entry for User 1, then the File.Copy from the shared directory to User 2's local directory works fine.
Note that both users are assigned to a group with read, write, modify, etc to the shared directory (but not 'full control').
This doesn't seem like that unusual of a situation. We haven't (yet) tried to see if the application can programmatically remove the security entry created on the checkin - even assuming that's possible, it would be nice not to have to resort to that. But we've not found any arrangement of security settings that works.
Any information or suggestions will be appreciated.
Thanks...

When a file is moved, Windows does not update the ACL to add or remove inherited permissions. This is presumably for backwards-compatibility reasons; the permissions model looked somewhat different in the earliest versions of Windows NT.
Your options are to copy the file instead of moving it, or to explicitly reset the permissions after the file has been moved.
If you want to explicitly reset the permissions, you can do this using File.SetAccessControl. To apply the inherited permissions for the new location, the FileSecurity object should contain an empty ACL and the AreAccessRulesProtected property should be false.
The scenario is as follows:
I have TeamCity set up to use AWS EC2 hosts running Windows Server 2012 R2 as build agents. In this configuration, the TeamCity agent service is running as SYSTEM. I am trying to implement FastBuild as our new compilation process. In order to use the distributed compilation functionality of FastBuild, the build agent host needs to have access to a shared network folder. Unfortunately, I cannot seem to give this kind of access from one machine to another.
To help further the explanation, I'll use named examples. The networked folder, C:\Shared-Folder, lives on a host named Central-Host. The build agent lives on Builder-Host. Everything is running Windows Server 2012 R2 on EC2 hosts that are fully network permissive to each other via AWS security groups. What I need is to share a directory from Central-Host so that Builder-Host can fully access it via a directory structure like this:
\\Central-Host\Shared-Folder
By RDPing into both hosts using the default Administrator account, I can very easily set up the network sharing and browse (while on Builder-Host) to the \\Central-Host\Shared-Folder location. I can also open up the command line and run:
type NUL > \\Central-Host\Shared-Folder\Empty.txt
with the result of an empty text file being created at that networked location.
The problem arises from the SYSTEM account. When I grab PSTOOLS and use the command:
PSEXEC -i -s cmd.exe
I can test commands that will be given by TeamCity. Again, it is a service being run as SYSTEM which, I need to emphasize, cannot be changed to a normal User due to other issues we have when using TeamCity agents under the User account type.
After much searching I have discovered how to set up Active Directory services so that I can add Users and Computers from the domain but after doing so, I still face access denied errors. I am probably missing something important and I hope someone here can help. I believe this problem will be considered "solved" when I can successfully run the "type NUL" command shown above.
This is not an answer for the permissions issue, but rather a way to avoid it. (Wanted to add this as a comment, but StackOverflow won't let me - weird.)
The shared network drive is used only for the remote worker discovery. If you have a fixed list of workers, instead of using the worker discovery, you can specify them explicitly in your config file as follows:
Settings
{
.Workers =
{
'hostname1' // specify hostname
'hostname2'
'192.168.0.10' // or ip
}
... // the other stuff that goes here
This functionality is not documented, as to-date all users have wanted the automatic worker discovery. It is fine to use however, and if it is indeed useful, it can be elevated to a supported feature with just a documentation update.
I'm using Apache 2 to run my localhost on Mac (Mavericks), and every time I add a file or a folder in the default directory /Library/WebServer/Documents (and its subdirectories) the system asks me to authenticate:
This is a problem specially when using frameworks like Symfony or Zend Framework because they can't have writing access to folders. What can I do to solve this?
Mac/Linux grants access on different levels:
Per user
Per group
Per everybody
The folder Library/WebServer/Documents outside of the logged-in user paradigm (you) therefore write access (and other access like execute) is only granted to the administrator of the computer (or so-called root) which isn't you however on most Mac environment the password of root is your password (different users with the same password).
You will want to modify Apache2 configuration and change the directory to a folder located within your user's directory which is something like /Users/{whatever is your username} (you will probably need to create the folder).
Once, you moved the content of /Library/WebServer/Documents into the new folder, make sure the permission are set properly. Refer to the following documentation at the chapter "How to Modify Permissions with the Info Window".
The reason why your Mac is asking for permissions to write files outside of your user's directory is for security reasons. Imagine if you download a file, execute it and grant access (by giving the root password) then the file could potentially be a virus and erase or do all kind of things on your computer.
I am able to get/set security attributes (group, owner, DACL, SACL) of files on a NTFS volume by using the GetSecurityInfo/SetSecurityInfo API. The handles I pass to these APIs must be opened with specific access rights (READ_CONTROL, ACCESS_SYSTEM_SECURITY, WRITE_DAC, WRITE_OWNER) which require certain privileges (SE_SECURITY, SE_BACKUP, SE_RESTORE) to be enabled while creating them with CreateFile, which is no problem at all if the files are located on an NTFS volume, and of course if the calling process has sufficient rights. There is a problem, however, if the files are actually located on a network share - creating the file handles would fail with ACCESS_DENIED(5) or PRIVILEGE_NOT_HELD(1314). I guess this is due to the fact that the attempt to create the file handle is actually made on the remote machine in the context of a network logon session which represents my user on the remote machine, and the required privileges are not enabled for that remote process. Is there a way I can get past this limitation, i.e. be able to get/set security attributes of files on network shares?
A similar problem is getting a handle to a directory on a network share. While being able to do it locally (by using FILE_FLAG_BACKUP_SEMANTICS), I understand that this particular flag is not redirected to the remote machine, which I believe is the reason I can't open a handle to a directory on a network share. Is there a way to do this?
Well, it seems I was the one at fault here - I have been testing this case with a user which, although an administrator on my local machine, is a regular restricted user on the file server, which caused all the trouble. You can copy security attributes and open handles to directories on a network share if you connect to it with a user which has sufficient rights on the file server which is sharing the resources.
