Installed AAD Domain Services with domain name "mydomain.com"
Added verified custom domain "mydomain.com"
Made "mydomain.com" primary
Created AAD user "admin#mydomain.com"
Converted temp password to permanent password
Logged into Azure with permanent password
Added "admin#mydomain.com" to domain administrators group
Ensured VM can see domain services for "mydomain.com"
When performing domain join, receive "The user name or password is incorrect"
I've tried the following credential combinations when doing the domain join (username : password)
admin : pwd
admin#mydomain.com : pwd
mydomain.com\admin : pwd
mydomain.com\admin#mydomain.com : pwd
None of these work and ultimately give me a lock out indication. I create additional users to continue trying these steps but nothing is working.
The user "admin#mydomain.com" you created must belongs to the Azure AD DC administrators group. Only members of this group have privileges to join machines to the managed domain.
For the details, you could refer to here.
The last step in the instructions from the link below was missed. Had to enable password hash synchronization to Azure Active Directory Domain Services and wait about 20 minutes. All worked correctly after that.

We have a C# web app for new customer intake, at the end of which the user enters a password value we apply to their new Active Directory user object when we invoke the userPrincipal .NET method to create their user object. Our code also creates an account in our Azure AD tenant, with the correct values (ImmutableID) set for Azure AD Connect to import and join both accounts on its next pass (30 minutes AADC cycle wait time not acceptable for our requirements). We sync our password hashes from on-premise AD to Azure AD, and we have password complexity enabled in AD, and we enabled and added our own vocabulary to the Banned Words (substrings) facility in Azure AD. We are considering installing the MS "Password Protection" service on our DC's that will also apply Azure Banned Words checking when passwords are updated on-premise.
To keep this question short, we really would like to pre-validate the user entered passwords against all the password policies, including the banned words list (assume we install that service on all our on-prem DCs), but we can't find a method or service in .NET that will pre-validate that a proposed password passes all the active password policies. Our users tend to use Azure Self Service Password Reset, on-premise password changes later on are rare. But in the C# programming, it appears you have to actually request an Add of a new AD username to get .NET to evaluate the password value and signal status back, from the userPrincipal method in .NET
Anyone got any tricky ideas how to get a password pre-validated against AD password policies without the context of adding an actual new user, but assuming that the sAMAccountName that will be submitted does NOT yet exist in Active Directory? We thought about creating a temporary AD user with hash or base64 of a GUID for a unique temporary usernames, get any password evaluation feedback back from .NET, then delete the temporary user object, but that's a lot of overhead just to check a password, would trigger replications and generate beaucoup EventViewer and AD-AuditPlus log events, much junk network traffic. Thank you.
lets say I have two on-premise domains (DomainA.org, domainB.org) and one tenant (domainA.onmicrosoft.com). Both domains are sync thanks to Azure AD Connect, so user from domainA can log to office.com, there is no problem. Hoever user from domainB getting this "Error validating credentials due to invalid username or password.", and when I changed password from portal.office.com for this user from domainB. I can log with this new password, but only to office365 services, its not sync to On-prem.
And another wierd thing is, that I cant change password for users from domainA.
Do You know where the problem is?
Thanks
I understand you have synced your 2 domains to Azure AD through Azure AD connect . Initially you have registered both the domain in Azure AD and verified both. Kindly check what kind of authentication you were using for Domain A since you were not able to change the password from Azure End. If you have federated that domain it is not possible to change from the cloud. If you were using password hash synchronization then the authentication will happen if cloud and you can change for managed domain.
I request you to go through this article about password writeback . When you are getting an error message while logging before resetting the password kindly note the correlation ID and time stamp and need to get a support ticket since it will be due to multiple reasons.
I am trying to create a new service principal using the command below using azure cli v2.0.
az ad sp create-for-rbac --name ServicePrincipalName
Changing "ServicePrincipalName" to a valid URI of "http://ServicePrincipalName", which is the required format used for service principal names
Found an existing application instance of "abcd-8f27-47cf-9976-xkkfigif5e1de". We will patch it
Insufficient privileges to complete the operation.
I am not sure what privileges the Azure Admin of my tenant should assign to my user so i can create a servicePrincipal any guidelines or document pointers please
First, you have to know what this command will do. The command az ad sp create-for-rbac --name ServicePrincipalName will create an AD App(app registration) along with a service principal in your tenant, the AD App will have an Application ID URI named http://ServicePrincipalName, a Display name named ServicePrincipalName. Then the command will add the service principal to your subscription as a Contributor.
The error you got means there is already an AD App with the Application ID URI equals http://ServicePrincipalName existing in your tenant. And you are not the Owner of the AD App. (Note: in the tenant, the Display name is not unique, but the Application ID URI is.)
To solve the issue and use this command successfully, follow the tips below.
1.Change the ServicePrincipalName to a different one. (Or if your admin allow you to use the existing AD App mentioned above, just let him add your user account as an Owner to the AD App. - not recommend)
2.If your account's User type is just a Member in the tenant. Make sure in the portal -> AAD -> User settings -> Users can register applications is Yes. If your account is a Guest , except the Users can register applications need to be Yes, also User settings -> External collaboration settings -> Guest users permissions are limited need to be No.
3.Your user account should be the Owner of the subscription. Otherwise you can create the service principal successfully, but you cannot add it to the subscription.
On a Windows 10 Azure AD Joined device the local Administrators group includes:
AzureAD\Admin (S-1-12-1-38678509…)
S-1-12-1-3346315821-114…
S-1-12-1-445845933-119…
Note that in this example the device was joined to Azure AD via Settings after already being set up with a local admin account.
That list would include the Azure AD user that performed the join and I assume the Azure AD global administrator role and Azure AD device administrator role. (based on info here https://learn.microsoft.com/en-us/azure/active-directory/devices/assign-local-admin)
It seems that the SIDs are being generated by Azure AD and are pushed (along with other bits of info) to the client in an ID token (based on info here https://jairocadena.com/2016/02/01/azure-ad-join-what-happens-behind-the-scenes/comment-page-1/#comment-3506)
However I can't find any tools that show a SID associated with an Azure AD entity. Does Azure AD in fact generate these SIDs and if so, is there any way to expose them to verify which SIDs match an entity?
I found an answer to this old question, and i think there are still people who can benefit from the answer. Before getting to the truth i tried to convert those SIDs to AAD usernames. Only to discover there is no SIDs in AAD only (cloud only) users.
https://www.petervanderwoude.nl/post/managing-local-administrators-via-windows-10-mdm/
Every Azure AD joined device contains two SIDs (one representing the Global administrator role and one representing the Device administrator role) that are by default part of the local administrators.
AAD Joinded device Administrator group
The SID of the Azure AD user is S-1-12-1- followed by the unsigned integer representation (4 parts) of the Azure AD Object ID.
https://kb.policypak.com/kb/article/862-how-do-i-get-azure-ad-sids-and-use-them-with-item-level-targeting/
If you want to get the user SID on the device, you could run the below command:
wmic useraccount get name,sid
It will return the local user list:
To get the SID for the current logged in domain user, you could run the command:
whoami /user
The return like this:
I have 2 users in my AD installation with the same CN
CN=jack,CN=Users,DC=xyz,DC=com and
CN=jack,OU=abc,DC=xyz,DC=com
When I try to authenticate to the AD Server using the Apache Directory Studio client and give the following credentials
User: jack
Password: <password>
the authentication fails. The following credentials work
User: CN=jack,CN=Users,DC=xyz,DC=com
Passwprd: <password>
When I have only a single user CN=tom,DC=xyz,DC=com with a given CN
I am able to login with
User: tom
Password: <password>
without having to specify the entire DN (CN=tom,DC=xyz,DC=com) .
I need to write a module to authenticate users against an AD installation. I have with me only the usernames and passwords and not the fully qualified BASE DNs. I cannot bind to the AD server to be able to use filters like (&(objectCategory=person)(objectClass=user)(sAMAccountName=jack)). How do I do this as the problem it seems happens when there are more than one user with the same CN ?
EDIT: Can I configure the AD server to bind against mail address/sAMAccountName of the users instead of CN ? This would solve my problem as these are unique while CN's are not
I found the attribute I was looking for --> userPrincipalName (UPN) . This has a unique value in Active Directory and can be supplied as the user name while attempting to authenticate. So now I need a list of UPNs and the corresponding passwords for login.
Check here too.
What kind of login are you doing in your 'module'? If you cannot bind and do an ldap query, then what interface are you logging in with? You need to configure whatever that is to use sAMAccountName as that is the only guarenteed unique per domain name. Of course if you have more than one domain in the forest then they only have to be unique per domain, so that may not work so well.
If you are only able to do an LDAP bind as the user, and not query. Perhaps you could try to connect as sAMAccountname=jack as you pass credentails.
