how to get user's ou programmatically with ldap C++
Well if you can get the users full DN, which is usually needed for the bind, then chop off the first something=something, and you have the OU.

I'm trying to create an App which has a log in page where user should be authenticated using azure AD. Basically the App has a log in form where user puts his id and password from ad and django should check with ad and allow him in or not. Later on ofc would like to add permission depending on AD group.
So far I searched a lot on the internet and found nothing. Could you guys help with some example or link to documentation what I could use.
First of all, I'd like to suggest that you don't do that.
What you are asking for is ROPC flow: https://joonasw.net/view/ropc-grant-flow-in-azure-ad.
Usage of this flow is not recommended unless this is for migrating a legacy application (which is the original purpose of ROPC).
It also won't work if the user has MFA, an expired password etc.
There is usually no reason why you'd want to handle user passwords when using a federated identity provider.
Is there any way to get users' system account? I want to make authorisation in my prog with Windows account. Trying to use Active Directory, but it only helps with names and other information, but what about passwords? I understand that I can't get passwords in free access, and I don't need this. But is there any way just to compare input string with real user's windows password?
Or is there any other way to embed authorisation into my program with windows users' accounts?
You may start with NetUserEnum, and with NetQueryDisplayInformation.
There is no way to determine password of a user.
You may use LogonUser API to authenticate users based on password they'd give on your logon window. You should not keep the password after this API succeeds - that's a breach of safety.
Use CredUIPromptForCredentials for asking the user credentials.
The easiest way is to observe that you are in fact running in a login session for the current user, so he does know his password. From there on, Windows will handle all authorisations automatically.
I need to differentiate one of requirement functionality based on the local user account and domain user account in a domain joined system.
How can I detect currently logged on user is a local user account or domain user using C++?
Please suggest.
Thanks in advance.
There are probably several ways, but an easy one is to use GetUserNameEx and request a format that isn't available in a non-domain context:
If the user account is not in a domain, only NameSamCompatible is
supported.
we have authetication as file system in our application server. Now i am trying to implement AD support into existing authentication within our application server, we need to add multiple AD support,
scenario
so i added an application to configure the multiple LDAP, now i found that login to server will be based on DN, so i expect that user should know the base DN,
but how people will know base DN.
i can provide more detail if needed.
Since you're dealing with AD, you can simply bind with the sAMAccountName or UPN. Alternatively, you can use a hard coded account to search the user with (e.g. (&(objectCategory=user)(objectClass=person)(sAMAccountName=%s))) and get the DN from there.
With both options, the user don't have to type in (or even know) their DN.
I am working to set up SSO for our intranet the idea is that a user would login to their workstation using their active directory username and password. Then a small application would run at login that would send some uniquely identifiable information,user name, and computers MAC address to the server were it would be entered into a database with a time stamp. Then when the user accesses the intranet a java applet would send the users mac address to the server and compare it to the database entry to see if it finds a match within a given time frame, if it does then it signs the user in and removes the entry from the database.
Unfortunately our intranet is not running on IIS so I can't use NTLM to do authentication which would be easier but not cross browser compatible which is one of the requirements. NTLM is also not an option because our intranet is only accessible in the form intranet.company.com and as far as I know NTLM does not work with addresses in that form.
Okay now onto the question. I am currently in the process of creating the client authentication application in C++ and need a way to get some unique identifier or token that would differentiate a legitimately logged in Active Directory user from some one who got a hold of the application and changed their local username to an AD user.
Yes I know this is probably the wrong way of doing it but right now it seems like the only option. If you have any suggestions beyond not doing it please let me know. Also I am aware of the huge gaping security hole it creates if you can think of a way to patch up that hole with out NTLM be sure to let me know.
AD is just Microsoft's implementation of Kerberos. One of the core features if Kerberos is to create such permission tickets. So, on that side your solution is not a hack at all. It's just the validation part that looks like a car crash.
However, I'm entirely lost at the client-side problem you have. The entire point of AD or Kerberos in general is that you can't spoof an authenticated user. You just ask the OS for a ticket for the logged-in user. It doesn't matter who gets hold of your app, or or what his local username would be. The OS knows precisely who is logged in.
