I want to connect my samba active directory server with my nextcloud. I cant find ANY information if samba4 has ldap or not? or how i could install openldap with it so that my active directory accounts and passwords are the same as in the nextcloud.
How to configure LDAP on an Samba4 Active Directory Server?
• Samba4 does have support for LDAP server but it has to be integrated with Active Directory or OpenLDAP to provide a schema and other related attributes to be used with other applications dependent on it for authentication.
• And since, configuring OpenLDAP as a backend for the Samba4 server is considered as legacy because it is best integrated with its own LDAP server in AD mode. But still if you want to configure OpenLDAP in the backend with Active Directory providing authentication to external applications, the directory schema will still be AD schema. So, you will have to update external applications accessing the directory using, such as you must do it when you use the Samba internal LDAP server. Additionally, you will have to import attributes manually from the old LDAP server that are not included in the AD schema. Even though, if you want to configure OpenLDAP as the backend with Active Directory, please find the detailed steps in link below: -
https://ubuntu.com/server/docs/samba-openldap-backend
• Also, please note that it is not planned to support OpenLDAP as backend for Samba AD as a significant part of the complexity of the AD DC is in the LDB modules such as creating a general-purpose OpenLDAP back end requires rewriting many of these modules as OpenLDAP overlays, outside the standard Samba programming environment wherein specific problems include the metadata required for both DRS replication and dirsync, schema manipulation, transactions, and access control lists. Please find the below link for detailed steps on configuration of ADDC on Samba4 server and integrating it with internal LDAP server: -
https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller
• Also, on connecting your Samba4 AD server with nextcloud, you can do it so readily as Nextcloud ships with an LDAP application to allow LDAP users (including Active Directory) to appear in your Nextcloud user listings which will authenticate to Nextcloud with their LDAP credentials, so you don’t have to create separate Nextcloud user accounts for them. Please find the below link on detailed information for its configuration: -

We have an AD in MS AZURE cloud and IBM Access Manager in our in house datacenter.
I like to know what is the best way to synch users between these 2 system?
But that I mean, user will be added to AD in cloud. at the same time I want the same user to be added in Tivoli Access Manager. I am looking for the best approach
Thanks
Microsoft Azure Active Directory Adapter is an interface between a managed resource and the IBM® Security Identity server. The Microsoft Azure Active Directory (Azure Active Directory Adapter) uses the Tivoli® Directory Integrator functions to facilitate communication between the IBM Security Identity server and Microsoft Azure Active Directory (Azure Active Directory).
Adapters can be installed on the managed resource. The IBM Security Identity server manages access to the resource by using the security system. Adapters function as trusted virtual administrators on the target operating system. The adapter creates, suspends, restores user accounts, and other functions that administrators run manually. The adapter runs as a service, independently of whether you are logged on to the IBM Security Identity server.
The adapter automates several administrative and management tasks.
You can use the adapter to automate the following tasks:
Create, modify, suspend, restore, change password, and delete a user.
Create, modify, and delete group.
Reconcile user and user attributes.
Reconcile group and group attributes.

I have few very specific questions to come to a understanding on Active Directory usage:
ADFS are the services/software to enable SSO login to applications using a single url for users stored in Active Directory. Right?
LDAP is a protocol that exposes other functionalities like fetching users, deleting user, authentication user via bind method etc. stored in Active Directory. Right?
Then can't LDAP and ADFS both work on the same Active directory? This link:
LDAP support in ADFS got me confused in where it is referring to LD and AD as separate entities.
Can't I apply both the mechanisms on same AD? I only have knowledge of LDAP. Trying to learn ADFS.
ADFS provides SSO capabilities for SaaS services and Modern LOB applications. Traditionally, it uses identities stored in Active Directory Domain Services to validate the credentials for a user. In 2016, we also added support to include identities stored in any 3rd party LDAP directory.
Irrespective of where the identity is stored ADFS offers SSO across the applications that trust it.
Hope this clarifies.

AD stores users, groups and credentials.
To access an attribute in AD, you use the LDAP protocol via e.g. the C# Directory Services API.
ADFS handles authentication against AD and also adds a federation layer on top of AD.
The correct way to access AD attributes via ADFS is to use claims-based authentication whereby you configure ADFS to provision the attributes (as claims) into the token and then extract them on the client side.
I'm trying to secure my CDH cluster using Kerberos but I want to use the user info that I have in my Microsoft Active Directory.
Is there a way to use MS AD as Kerberos user lookup source?
Yes, MS AD is actually an umbrella set of technologies working together to provide enterprise directory services. The big four, as I call them, are Kerberos, LDAP, DNS and Group Policy. Each MS AD domain controller runs a Kerberos KDC, which is a database of user, service, and computer principals.
This is perhaps a dumb question, but I am entirely new in this area and I apologize in advance if it is.
I understand the relationship between Active Directory and LDAP (i.e. LDAP is a protocol that a database based system like Active Directory may use to perform authentication tasks).
However, what does a Central Authentication Service (CAS) Server need to have in addition to an AD to support SSO? Essentially, I'm trying to find out what's the difference between an LDAP server that runs AD and a CAS server.
Essentially Active Directory is a directory server by Microsoft that is accessible over LDAP. LDAP is an open standard protocol for accessing directory servers.
CAS is a server for authenticating users and providing single sign on across disparate clients. CAS can use Active Directory as a source for authentications. CAS can also use LDAP to authenticate users against LDAP capable directory servers.
Have you seen this page? It will hopefully illustrate the overall architecture for you.

I have windows server running ADFS server. I want to Connect to ldap server on it. My questions are
Does running ADFS Server already have LDAP Server running or need to do anything for that? I believe it is running already because I could see open port 389 and 636.
Assuming LDAP server is running, I was trying to connect to it using Google App Directory Sync to get list of users However I was not able to authorize. Is there any default credentials to connect? Or steps to get credentials for LDAP server?
Thanks
An ADFS server is not an Active Directory server - ADFS only extends Active Directory's infrastructure. Ports 389 and 636 are available because ADFS supports the LDAP and LDAPS protocols for communication, and as such, ADFS can retrieve user attributes from Active Directory, and it can also authenticate users against Active Directory. If you already have a directory server running, you need to add it to ADFS as an account store.
There are no default credentials - just use an administrative account that exists in your Active Directory store, as mentioned in point one.
To clarify on terminology for ADFS:
Account Store in ADFS: This is the account store that ADFS authenticates the user against with some form of credential (e.g. Username/password). By default ADFS connects to the Active Directory Domain Services and adds it as a special account store that cannot be deleted. So, any users in this active directory forest or in it's trusted subsystem can authenticate to ADFS. So far, ADFS only supported Active Directory as an account store and nothing else. With Windows Server 2016, it now supports connecting any LDAP v3 compliant directory as an account store. ADFS does not open LDAP ports as it is not an LDAP server. If ADFS were collocated with a domain controller, you would see LDAP ports open.
Attribute Store in ADFS: This a store where you can augment additional information about the user AFTER the user authenticates. By default ADFS has a default attribute store for ADDS that is setup by virtue of the install. Beyond this, it has in-built adapters that can be instantiated to connect to SQL or ADLDS (lightweight directory service). It also has an extensible API to connect to any other attribute store of your choice via .NET. People connect to Oracle/SAP data base, FIM metaverse etc.
#Srikanth: You will use the ADFS claims language or the UI to query for additional data using the attribute store model. In the UI, you would see it when you configure the issuance authorization rules or the issuance claims rules.
Hope that helps
