I have a problem: I have 2 windows servers - the first one has Active Directory with all the client's user names and the other one has vpn server. I want the clients to use the Active Directory to authenticate to the vpn server - is there a configuration to do so? Thanks

Windows Authentication, Windows Server 2016 (or any version really)
When this is turned on in IIS10 this just authenticates against Active Directory, the user does not necessarily need to be a user on the server that IIS is sitting on right ?
Sorry for the dumb question
this just authenticates against Active Directory
Yes and no. It's called "Windows Authentication" and not "Active Directory Authentication" for a reason. It allows the website to authenticate any account that the server is capable of authenticating.
If the server is joined to a domain, then that can be an Active Directory account on the same domain or on any domain that domain trusts.
But it can also be a local account that only exists on the server itself - and that is true whether or not the server is joined to an AD domain.
i have configured kerberos authentication when accessing to file server.
there is no need for logging in when i map drive and acccess to the file server
Just a curious question, if i can add additional server name to be used for authentication
for example.
currently my file server name is server01
when i map network drive through server01 / IP address, there is no issue.
when i tried to access through a server name server02, then i get an error in mapping the drive.
is there any way i can do this by allowing multiple server name to be allowed for kerberos authentication ?
thanks in advance for any advise
You can map as many file shares as possible you want with Kerberos authentication on a Windows domain joined system if the file servers hosting the file shares are joined to the same domain as the client Windows system accessing them.
Thus, you may have multiple file servers in your domain environment but they all should be joined to the AD domain for the Kerberos authentication to work successfully and let the users accessing and mapping the file shares authenticate through it as Kerberos needs a KDC (Key Distribution Center) due to which Active Directory authentication is required.
Please find the below dependencies for Kerberos authentication to work successfully: -
Operating System --> Later then Windows 2000 for client and Windows 2003
TCP/IP Network Connectivity --> Should exist between DC, client, and the target server
Domain System --> DNS must be functioning and accessible for the client
Active Directory Domain --> Necessary to use Kerberos authentication
Time Service --> Time source should be same and synchronized on all the network computers
Service Principal Names --> Kerberos authentication needs to have an SPN set for it so that clients can identify the service on the network

"a specified logon session does not exist. it may already have been terminated" after i joined the device to azure active directory
-i can't access our shared folder in our server after i joined the device to azure AD and use office 365 account (Please see click the link below to see the error image for your reference), but if i use local administrator of the device i can access the file server using the credentials with no problem, please note that we don't have an premises active directory or GPO, kindly help me.
a specified logon session does not exist. it may already have been terminated
Instead of specifying just "binos" as your username, add hostname with back-slash like so:
yourhostname\binos
In most cases, this will fix that error.
To access the share, the server would also need to be azure ad joined. which you cannot do with windows server, you would need azure ad Domain Services (AD DS) on azure, then join your file server to that.
Only Windows 10 devices can be "azure ad-joined devices"
If you don't want to do that, you could create a azure file store, and secure it using your azure ad / rbac, then map that on your devices.. that would probably work too.
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

what is the difference between active directory and directory naming service in Server 2003
AD contains the users of your servers, computers in the network etc.
DNS is the URL your server will listen too, for example http://server01.lan.company.com
