LDAP/AD Experts,
It might be simple for you but its challenging task for me!.
"ldap queries - need the dn of the users who are authenticated via ldap protocol and their IP address"
We are migrating authentication out of AD/LDAP.
We’re looking to migrate applications that are directly using AD for employees.
Its not specific to OU and Group but overall active directory.
We have plenty of applications which uses AD/LDAP for authentication.
How do I pull such data? At least need to have user details.
Getting the DN of a user is easy with any ldapsearch utility.
There is no method to obtain "the users who are authenticated" from LDAP. You could find the "time" a user did last Authenticate, regardless of how, from the lastLogon or LastLogonTimeStamp.
Generally, the IP Address of the user is not available as part of the user entry within Microsoft Active Directory.
You might be able to obtain this from some power-shell script, but I was unable to find anything from a quick search.

I have an application that needs to sync periodically to my directory service (OpenLDAP or AD).
To do so, it is necessary to bind an admin account with a DN and password, to access users on LDAP.
As far as I understand, there is the possibility of using anonymous, however for security reasons, its use is not recommended.
Since this periodic synchronization is done automatically by a routine (hourly), I need to store in addition to the account DN, also admin password in the application database.
However, passwords are usually sent to be authenticated in plaintext against
directory service (within a secure SSL / TLS connection) and the directory service itself that finds its password stored in plaintext or some hash (md5, sha-1, etc.)
How to ensure the security of admin password stored in database for synchronization with LDAP? Or, is there a best practice to implement a sync periodic using LDAP?
Applications examples that require password (admin) to read LDAP.

(https://docs.moodle.org/37/en/LDAP_authentication#Bind_settings)
Sugar CRM (https://support.sugarcrm.com/Knowledge_Base/Password_Management/Configuring_LDAP_Authentication_Using_Active_Directory/#Prerequisites)
But it does not clear how the password is stored.
It's true that anonymous bind is disabled by default in Active Directory. However, if you are just reading, you don't need an "admin" account. You need any account. The account does not need to have any special permissions. You just need something that can authenticate to the domain.
But if you're going to be authenticating users, then you will need to get the user's password, and you can just use the user's credentials to read from LDAP. That would be true for both AD and OpenLDAP.
Is there a way to detect and monitor that a service principal is only being used from a specific set of IP addresses? I do not want to IP restrict my entire directory. I have premium AAD and I think it has features that I might be able to utilized but I cannot do much testing. I’m currently struggling on how to detect if a SP has been jeopardized and how to prevent it.
If you want to use IP as conditions for the user to sign-in, you could use Conditional Access to make it. But the Conditional Access is used for the entire tenant.
And the features of Azure Active Directory Premium includes:
Company branding
Group-based application access
Self-service password reset
Self-service group management
Advanced security reports and alerts
Multi-Factor Authentication
Forefront Identity Manager (FIM)
Enterprise SLA of 99.9%
For the details, please read here.
I have to implement Single Sign on with following user case:
We have three kinds of users:
1) Corporate employees [Stored in Active directory]
2) Clients can access our application
3) We have hosted separate application for each client and clients employees can access this application [hosted on our server] and number of employees can be have million.
So we cannot store use credentials in active directory because we need per user license to use.
Please help me to find better solutions
ADFS only works with AD. The next version of ADFS will work against LDAP so that's a possibility.
I would look at Azure Active Directory (you could use something like AAD Sync. to migrate your existing AD users) or something like OpenAM or PingFederate (both of which are Java based) which you have to pay for or something like shibboleth (Java based but open source). These all support LDAP.
Or if you want to go the SQL Server route, look at thinktecture's identityserver.
What is the difference/relation between ADAM, Active Directory, LDAP, ADFS, Windows Identity, cardspace and which server (Windows 2003, Windows 2008) uses what?
Active Directory is a server component for administrating windows domains and storing related informations like details about users. It provides implementations of the network protocols LDAP, DNS, CIFS and Kerberos. It's part of Windows Server 2003 as well as Windows Server 2008 with some modifications in the latter case.
ADAM was somewhat like the little brother of Active Directory. It only contained an implementation of LDAP. With Windows Server 2008 it was renamed to LDS, Lightweight Directory Services. ADAM/LDS can also be installed on non-server versions of Windows.
LDAP is a protocol for administrating the data of a directory service. Data within a directory services are stored in a hierarchical manner, a tree. Entries within that tree can contain a set of attributes where each has a name and a value. They are mostly used for storing user related informations like usernames, passwords, email addresses and so on, as there are standardized schemas for this purpose and it's widely supported by applications.
ADFS is a technology which enables Single Sign-On for users of web applications within an Identity Federation. In a very short form: Imagine two organizations which have their user data stored within an active directory. Now each organization wants to give the users of the other organization access to its web applications, but with the restriction that the user data itself should neither be copied nor be fully accessible to the other organization. Thats the kind of problem ADFS can solve. May require an hour of reading & researching before fully understood.
Just to fill in the gaps above:
ADFS is an example of a STS (Security Token Service). STS's can be configured to have a trust relationship with each other. Imagine you have a company which only has internal users and they want to expand to external users. That means that all external users have to register, get a user name, password etc. Perhaps the company doesn't want to store all this stuff. They realise that most of their external users already have an OpenId account. So they federate (trust) their ADFS with an STS that accepts OpenId credentials.
When an external user wants to access the company website, they are asked what kind of user they are via a drop down. They select OpenID. They are then taken to the OpenId site where they authenticate. The user is then redirected back to the company ADFS with a signed token which states that OpenId has authenticated the user. Since there is a trust relationship, the ADFS accepts the authentication and allows the user access to the web site.
None of the OpenId credentials are stored by the company.
Effectively, you have outsourced authentication.
ADFS currently runs on Windows Server 2008 R2.
For Windows Identity (in the context of ADFS) I assume you are asking about Windows Identity Foundation (WIF). This is essentially a set of .NET classes that are added to a project using VS that makes the application "claims aware". There is a VS tool called FedUtil that maps an application to a STS and describes the claims that will be provided. (A claim is an attribute e.g. name, DOB etc.) When a user accesses the application, WIF redirects the user to the mapped STS where the user logs in. WIF then provides the application with a set of claims. Based on these, the application can alter flows based on the user claims. E.g. only users with a claim type of Role with a value of Editor can alter pages.
WIF can also act as an Access Manager E.g. only Editors can access this page. Other users simply receive an error.
In WIF, an application is referred to as a "Relying Party" (RP).
WIF inside VS requires Vista or Windows 7.
Since STS's can be federated with each other, each STS can provide a group of claims.
E.g. in the example above, the OpenId STS can provide the user's name while the company ADFS can provide information not pertinent to OpenId e.g role in the company.
Cardspace is a mechanism to authenticate via a digital identity e.g. an enabled application can ask you to login by selecting one of your "cards", one of which might be e.g. your personal X509 certificate. The application would then check this against the credentials it has stored.
In February 2011, Microsoft announced that they would no longer be developing the Windows CardSpace product.
The setup:
There is a central AD domain (CENTRAL) and multiple seperate forests, each of which has their own domain (BRANCH1, BRANCH2, BRANCH3)
There are 2-way domain trusts between CENTRAL and all other domains.
An application I'm working on runs on the CENTRAL domain and performs LDAP searches on all domains, using the credentials CENTRAL\ldapreader.
This works perfectly for CENTRAL and BRANCH1, but BRANCH2 and BRANCH3 refuse the connection with an invalid credentials error. If the search instead uses an account in those domains (BRANCH2\ldapreader, etc) then the search works fine.
What level of permissions are needed to read AD as an LDAP server? Everything I've found indicates that this is allowed for AUTENTICATED USERS, which should work fine with CENTRAL\ldapreader due to the two way trust but that isn't the behavior we're getting.
I think the permission you're looking for is "List Contents". You should ensure "CENTRAL\ldapreader" has this permission for BRANCH2 and BRANCH3.
I'm wondering if you set up the trusts with selective authentication or forest-wide authentication and whether you can manualy browse BRANCH2 and BRANCH3.
