I have a problem where Users[1..10] have Full Mailbox Access to UserA's mailbox.
UserA, now wants to restrict access so that all the Users[1..10] have access except to the "Sent Items" and "Deleted Items". In this User2 & User3 should carry on having access as previously requested.
Is there a simple way for me to restrict access to the folder without having to remove the Full Mailbox Right permission and apply each individual's user rights on each specific folder?
Sorry if this has been asked before and answered. I did look but I think Google could not understand my query.
I am doing this via powershell as this will need to be repeated numerous times across multiple mailboxes.

What is the best option to implement such security in Casbin?
I have several folders, each of them has its own security (i.e. the users allowed to accede it)
But that's not enough, the action a user is allowed to performed in a folder depends on user's group
As an example:
alice can be admin for folder1 so she can read and write within it
alice can be user for folder2 so she can only read
I was thinking of using 1 group per role (user, admin) and 1 group per folder, however this is not fine because once a user is assigned a role, he cannot change
I looked at RBAC with domains and this can work until I duplicate all my policies for each folder (yeah, all users will always have the same rights in folder...) because domain must be part of the policy itself
Do you have any suggestion on how to achieve this?
Thanks
I am trying to unlock several accounts in Active Directory through PowerShell, but I can't figure it out how to link every condition into the query
The conditions are:
-The account should be enabled
-It shouldn't be "memberof" some groups (whose I'm not able to unlock, like Administrators)
I don't have full control over accounts, I'm not able to unlock some of them, due to my privileges, so I'll be very helpful if can you help me to know or simple discard the accounts that I'm not able to unlock
I've just tried this
Search-ADAccount -LockedOut | Unlock-ADAccount
(Very poor attempt, i know, I'm very new on this technology)
But gives me an error because of my account's privileges
It says: access rights are insufficient to perform the action.
The error is the same for different CN accounts
But gives me errors because of my account's privileges
That 's' in "errors" is key. If you're getting more than one error, that means that errors don't stop it from continuing on to the next account. That is, actually, how PowerShell works by default.
So what you are doing is already working the way you want it to: it is unlocking all the accounts that you have access to.
Of course, this is just a band-aid on the real problem. It won't eliminate calls for the problem accounts, and it undermines the added security you get by locking accounts in the first place.
I'm able to unlock some accounts, but when I run the command
Unlock-ADAccount, I think it try to unlock accounts like
administrator, some disabled acc, for which I don't have permission to
modify, but if I run that command on an individual "regular" account,
it gets unlocked
This due to the blocking of inheritance of permissions applied to domain Admins accounts & due to Security Descriptor propagator (SDPROP)....
It's not recommended, as it's a critical mechanism in my opinion, but you might :
create a specific delegation for a group
and append this group to the Access Control Entry (ACE) of this kind of template folder for admin permissions: 'CN=AdminSDHolder,CN=System,DC=example,DC=com' (with the help of LDP.exe)
I've been working on a project that allows users in our domain to edit 3 Active Directory Attributes on their own Object, this has been written in Python and the only issue I have now is user permissions on these attributes.
Two of these are custom, the third is the Location(physicalOfficeDeliveryAddress).
I have looked everywhere and only found documentation on how to give permission for users in a group for these attributes but for ALL users or limited by group.
I'm looking to apply the permission under the Identity Reference: NT AUTHORITY\SELF so that users may only edit their own attributes.
In less words, I'm looking to write a script that will delegate permissions for three specific attributes to ALL users in the domain but only for themselves(NT AUTH\SELF).
I have a loop that will perform it for each user, I just have hit a brick wall in what to include in the loop..
Any help would be appreciated.
NT AUTHORITY\SELF is one of Windows' well-known SIDs, with a SID of S-1-5-10.
So you do it the same way you would for any other account, but grant the permissions to S-1-5-10 instead.
If you show us the code you're working with, we might be able to help you with where to plug in that value, if you need.
I added a group to a site. The users were then added to the All Users group. I then removed the group, but the users remained.
Is there anyway to clean this up so that the users get deleted?
Thanks
To be clear, you want to delete the users that were in the group?
Creating and deleting groups does not create or delete users. To delete users you need to go to the users tab and select the users you want to delete.
Also, keep in mind that if the user owns content you will get a message saying:
"[user] was unlicensed" instead of the expected “[user] was deleted”
message.
The “unlicensed” message displays because the user who you want to
delete is a workbook or project owner and therefore cannot be deleted.
In other words, a user can only be permanently deleted from Tableau
Server if he or she no longer owns a workbook or project.

Tableau is not good with Active Directory when it comes to removing users. If you ADD Active Directory account and set up sync, it will add a new user who will be added in AD group but once you remove AD group it will not remove any users who were in AD group.
In order to remove those users, you need to go to all users and delete the Users manually which defeats the purpose of using AD groups.
I need to compare AD users permissions (one user can "unset" an attribute and another cannot, both can change it).
How can I dump/compare user account "effective permissions" which I find when I go to user account > Security > Advanced > Effective Permissions (and select an user account) with powershell?
Using Quest Free PowerShell Commands for Active Directory is simple:
Get-QadPermission useraccountname -Inherited
or better way:
Get-QADUser -Name useraccountname -SecurityMask DACL | Get-QADPermission -Inherited -SchemaDefault
This return all effective permission Inherited or Explicit assigned for the user 'useraccountname'
The comparison can be made with compare-object.
A very simple example:
compare-object (Get-QADPermission userA -Inherited | select Rights) (Get-QADPermission userB -Inherited | select rights)
We were in a similar situation once and needed to know who all could delete one of our main OUs, so we figured that maybe we should dump the ACL on the OU and look for everyone who had delete permissions on the object. Of course dsacls was very helpful in this regard and we could dump the ACL on it easily.
But then, as we started looking at the ACL, we found that it had almost 60 permission entries, including about half a dozen deny entries, some of which were direct and others inherited. We initially didn't consider the denies and came up with a list of about 200 users who could delete the OU, but that did not seem right (; it seemed too high.) Then, we realized that we had to intersect the denies with the allows!
So we flattened all deny permissions, and all allow permissions, but then we had to figure out which of these denies would apply, since some of them were inherited, and I believe the inherited ones don't negate any direct allows, so that took some more pain-staking work, and while doing it we realized that some of those inherited permissions did not apply to the object, so we had to start from scratch!
Finally, we almost gave up, and when I asked one of our Enterprise Admins, he said what we needed to do was determine Effective Permissions on our OU, and he pointed us to the Effective Permissions Tab in the Active Directory Users and Computers snap-in.
So we launched ADUC and navigated to the Effective Permissions Tab, and figured it would be a matter of clicking OK somewhere. However, we soon realized that it needed us to enter each person's name individually. Now, we have almost 2000 people in our environment, so there was no way we could put in 2000 people's names one by one. The other thing was that even for a single person, it would show us all the effective permissions for that person, and in technical terms, which we would have to further refine.
We then figured we'd give Powershell a shot, and looked at many options to do this using Powerhsell, but there was no easy to determine effective permissions in AD using Powershell, which was disappointing. In particular, we tried Quest's free PowerShell commands Get-QadPermission useraccountname and Get-QADUser -Name useraccountname, but we were disappointed to see that this only retrieved the list of all permissions specified for a given user. It did not reveal the Effective Permissions granted to a user. We found ourselves having to start with the results it brought back to then manually try and determine effective permissions, which was not worth our time.
So, we had almost given up hope, but before quitting we thought we would just Google "Active Directory Effective Permissions Tool" with the hope that there must be something out there that could do this for us. I am glad we did because we found a tool that could do exactly what we needed: figure out effective permissions on our OU and give us the ability to export these effective permissions -
http://www.paramountdefenses.com/goldfinger_capabilities_true_effective_permissions_for_active_directory.html
We found that this tool (called Gold Finger for AD) has the ability to determine Effective Permissions on Active Directory objects, and provide the output such that we could easily see the list of all users who had "effective permissions" for a specific right on an object. For instance, we were able to use it to determine and enumerate the list of all admins who had "effective delete access" rights on the OU we were interested in.
It has turned out to be quite helpful for us, and maybe it could be of help to you too. I just thought I would share this because I've been the dsacls route and I wouldn't want you to go through the same pain we did in trying to manually do this. Its just too painful to do do manually.
