HI i follow all your steps but still my issue is not resolved.
1- SSPR is on / enabled.
2- Write back password to on-premise is also enabled.
When i try to reset it from Azure AD got the following message.
"Unfortunately, you cannot reset this user's password because your on-premises policy does not allow it. Please review your on-premises policy to ensure ...
If all users encounter the OAB update issue, are they distributed in the same database? Are the new user and old users in the same database? And are they using the default OAB or custom OABs?
Here are some troubleshooting steps and hope these may be helpful to you.
1. OAB generation:
You should check OAB generation cycle check point, the OAB is generated ...
The issue appears to have been resolved with Microsoft security patches deployed around the 3rd week of November. I suspect the initial patch was to address security issues but caused problems with Integrated Windows Authentication. These were resolved with later patches, however in Windows 10, the FQDN of the web site using Integrated Windows Authentication ...
I believe you can limit this by using group policy.
If you have a group policy which doesn't allow users to join the domain, then you will basically reduce the risk of disabled computer leaving and re-joining the domain.
As mentioned in the article I'm adding here, the lowest permissions for joining a computer to the domain would be an "Authenticated user"
Last logged on user isn't a property that AD computer objects track.
It can be, if you make it so.
Here's how it could be done:
1) Set up a scheduled task running as LOCAL SYSTEM on the computer(s) that you need to report last logged on user. The task will be configured to run on a schedule of your choosing and will execute a script you write to collect ...
Because I did not find a solution for the problem described by RichardP and although this thread is quite old I will add my own findings:
The solution - or at least part of it - seems to be to follow this specific paragraph in the aforementioned MS-Knowledgebase article literally (except for the names of the files, these don't seem to matter), I quote:
Turns out, even mix of virtual and actual users works! The guide is for Ubuntu 18.04 LTS, but should work on other Linuxes as well, although the file locations may change.
So, one way of doing it is this:
Create an appropriate directory on your CIFS server and set a single AD user with proper rights on it (eg. unix_server_user@domain).
Mount the CIFS share ...
Because it's just the index, you can repair this by performing an offline defragmentation of the Active Directory database.
This will drop and recreate the index. Only cost me a 3 minute outage. Clone and test if you can.
See MS article KB232122
Well the problem was somehow caused by the Cisco ASA that handles the traffic among the various LAN segments, even though no one claims to have changed something.
Thanks Trix for the info especially the FW ports, we had to manually add those plus some more. After adding the rule the operation is back to normal.
Is the 10.2.132.0/22 subnet defined in AD Sites and Services and assigned to a site?
Maybe someone typoed /24 instead or intended to break it down to class-C subnets and didn't add the additional subnets to the site definitions.
Are the clients registering themselves in DNS on the DCs? IF DHCP is doing it, the clients don't need to be on the domain)?
I asked the support center of BUFFALO and got an answer to resolve this problem.
The procedure is as follows:
In the NAS config, change the NAS to a WORKGROUP member once.
Change the NAS's name to an arbitrary one as you like.
Shutdown and Boot the NAS
Make the NAS participate in the AD domain again.
The domain controller recognizes the NAS as a new name ...
Great to hear you managed to get the server working again. I really recommend resetting the Directory Services Recovery Mode (DSRM) password now that the server is alive, so you have it if something similar would ever happen again. Then store the password in a secure place or in a password manager you can reach even if the domain is unavailable.
To reset ...
I'm still not sure how it worked but I have resolved the problem by the following way.
When booting, I pressed the F8 key and entered the boot options menu and chose "Safe mode and command prompt". After a while, the login screen appeared and typed the domain user name and the password which had been rejected in the previous tries. This time, I was able to ...
you need to browse to the AAD Connect folder in program files in powershell and run Import-Module .\AzureADSSO.psd1 then run update-AzureADSSOForest enter your domain credentials. Once this is done then launch AAD Connect and you will be able to enable.
This happens because the server was already associated with SSO
We solved it by performing a full restore to a 20-day old Acronis backup, then restoring AD to a current backup.
As commenters noted, having a single DC is risky. We will be converting the server to VMware ESXi and running 2 VM DCs, as well as other VMs to run other non-AD services, to reduce these risks.
You can use selinux/apparmor profiles to limit access for certain groups to ONLY the applications they need.
The advantage of doing it this way is that users will be restricted to only what you allow.
The creation of those can be particularly complex, so depending on how tightly you need to lock things down, you may not need to go this far.
For example ...
There are two methods (of which I am aware) to achieve this.
First (the easiest), you can add the desired accounts to the scope-specific seuciry group "Remote Management Users" group (the domain group if looking to access domain controllers, or the local group if looking to access a member server or workstation).
Alternatively, you can either register a ...
Using SSSD with AD as its identity provider, you can use the Active Directory user groups and users as Linux groups and users. See here (Ubuntu) and here (RHEL)
Once this is done, you can restrict access to a specific executable to a certain system group as explained in this answer.
Just make sure that old users are in the AD group and new users are not ...
On Linux systems, you can control the permissions of the binary that opens the GUI application directly. Let's say I want to restrict users to access Firefox on Ubuntu... If I type the command:
$ whereis firefox
firefox: /usr/bin/firefox /usr/lib/firefox /etc/firefox /usr/share/man/man1/firefox.1.gz
Its binary file is located on /usr/bin/firefox and we can ...
We upgraded over 100 virtual 2008R2 Servers with only two version changes.
We had no issues with drivers because they were all VMs.
There was no DC among the machines, we join 2019 DCs to the AD and remove the old ones after that.
Maybe driver support issues could be a reason why the migration info from MS states that it needs to be a three step version ...
I had the same problem, are you using GAM to do some bulk operations on G Suite?
We create the users with PowerShell on our own AD, then after sync with GCDS we do a reset of the passwords with PowerShell on AD.
then run the command:
gam update user emailaddress changepassword off
After this command the user will be able to login with the ...
Configure NSS to reference the directory for users and groups, such as with sssd. Groups do not have to be in /etc/group, that is why the NSS abstraction exists.
Confirm the correct user subset are members of this group in the directory (AD DS in this case). Use getent group on the Linux box.
Use the "directory" group in file permissions and elsewhere, as ...
Is it a good idea? Yes
Why is it not like this? In case you haven't noticed, Microsoft wasn't very good at security in the past, and some of the default configurations that aren't secure are still present. NetBIOS enabled on network adapters is another classic example.
In large forests with multiple domains, Domain Admins traditionally was not very ...
I should have Googled more. It turns out that an application-aware backup IS actually important for more than just preserving the state of AD on a domain controller.
A backup that is NOT application-aware is more or less what you'd get if you did an hard power off of a machine without doing a clean shutdown, as if the machine suddenly lost power. It is ...
To add a Linux machine to an Active Directory domain, you will need:
TCP / IP Config: Configure the DNS of the AD as DNS.
NTP Config: Configure the NTP server in DC
Packages: Install the necessary packages
SSSD Configuration: Configure the network authentication service.
Verification with the id command
Here is a guide, step by step:
This is a problem that can arise and it needs careful planning.
It is best practice to use a real existing DNS zone as your internal AD zone. This prevents conflicts with real-world external resources. As Esa suggests you can use a sub-domain to achieve this and this can help to prevent conflicts with, for instance, the public facing DNS you are running ...
Just in case you were still looking for the answer 11 months later, typically the cause of the "Caller Computer Name" being a Domain Controller, is that that particular DC is the one reporting the lockout.
DC1 has event 4740 saying that a user account was locked out reported from DC2.
If you go to DC2 and look for the same 4740 event, you will see that the ...
I'm assuming the domain DNS name is in fact abc.example.com and you're not referring to an actual host.
You don't manually allocate internal DNS entries for your domain root, if that's what you've done.
The way that AD creates a DNS entry for abc.example.com is by creating an A record for each DC in the domain root with a blank hostname (or an "@", ...
Please double check in ADSI. Or did you find proxyaddress, please try to change this, the ProxyAddresses attribute is where the aliases are stored.
Did you ever install Exchange on-premises server in this environment? If not, you could extend Active Directory schema to include Exchange attributes:
I know this is an old thread but I found it searching for a fix to this.
My best solution here is to use two ADUC windows. One does the search with the Distinguished Name shown in the results window. Then browse to the user in the other window.
All day long I do this two step process to modify something in AD.
The KB is the solution. And I test on my side. I just change the mailNickName attribute in ADUC and then do a manual sync via Azure AD Connect, it is synced correctly to Exchange Online:
You could test another account and check if this issue is only with this account.
In addition , you could check if there is any sync error in AAD connect:
The original question didn't specify whether the policy on the domain accounts should be applied at a domain level or on a specific local machine.
See @Massimo's answer for making a domain group policy.
For anyone who wants to apply this as a local policy on your Windows 10 Pro (not Home) machine,
Open the Local Security Policy editor by ...
One of your servers may already have it installed. If so, it may be possible to copy two files to the system where you perform the import:
(Use your locale if not en-US).
If you are performing the import using Windows 10 2018 H2 or later, ldifde may be installed by adding the ...
I really like the answer by Mathias R. Jessen.
Remove-WindowsFeature -Name AD-Certificate
as a PowerShell command; however, if the option Network Device Enrollment Service is already installed, so the above command will be not enough before uninstalling this feature:
PS C:\> Uninstall-AdcsNetworkDeviceEnrollmentService -Force
Now, retry Mathias's ...
Since it was a new test machine, and nobody had any suggestions, I decided to trash this VM and start again. This time, rather than following "Join Domain" link on the cockpit page, I followed the instructions to "manually" join the domain. This worked perfectly fine.
So, I don't know if I did something wrong or there is a bug in the scripts that are ...
Guessing here, but I would try 3 ways:
Using AD users on Linux (maybe by using SSSD)
Using Virtual Users on vsftpd (I think you'll need to ensure CIFS mounted filesystem files are owned by vsftpd user)
Doing the oposite: Install Samba and make admins & opers access file through it (the simpler solution IMHO)
Remind them of the shortcut to turn on Navigator, Windows + Ctrl + Enter. Also show them now to navigate Settings > Ease of Access > Navigator. This will help them on any Windows 10 machine they are using, joined to your domain or not.
If you implement user experience virtualization, Ease of Access settings are synchronized by default. A bigger project, ...
You want to add this to "TrustedPublishers" as well as the "TrustedRoot"
certutil -addstore "TrustedPublishers" *.cer
Create an empty OU in your on premises AD.
Reconfigure Azure AD Connect to synchronize only this OU. This will delete the Office 365 users that were synched incorrectly.
Connect to Office 365 with Powershell and remove the users from the Office 365 recycle bin:
