Which Kerberos setting defines the maximum lifetime ticket for a Kerberos TGT ticket?
Which Kerberos setting defines the maximum time skew that can be tolerated between a ticket’s timestamp and the current time at the KDC? The setting for maximum lifetime for user ticket defines the maximum lifetime ticket for a Kerberos TGT ticket (user ticket ). The default lifetime is 10 hours.
What does the acronym Ntlm stand for?
In a Windows network, NT (New Technology) LAN Manager ( NTLM ) is a suite of Microsoft security protocols intended to provide authentication, integrity, and confidentiality to users. NTLM is the successor to the authentication protocol in Microsoft LAN Manager (LANMAN), an older Microsoft product.
Which of the following is the name by which a client uniquely identifies an instance of a service?
A Service Principal Name (SPN) is a name in Active Directory that a client uses to uniquely identify an instance of a service. An SPN combines a service name with a computer and user account to form a type of service ID.
Where is NTLM authentication used?
NTLM authentication is also used for local logon authentication on non-domain controllers. Kerberos version 5 authentication is the preferred authentication method for Active Directory environments, but a non-Microsoft or Microsoft application might still use NTLM.
Why is Ntlm still used?
At its core, NTLM is a single sign on (SSO) tool that relies on a challenge-response protocol to confirm the user without requiring them to submit a password. Despite known vulnerabilities, NTLM remains widely deployed even on new systems in order to maintain compatibility with legacy clients and servers.
How long is a Kerberos ticket valid?
How long will my Kerberos ticket last? A ticket lasts for eighteen hours before it expires. You can find out when your ticket will expire, or if it has already expired, by typing klist in a terminal window.
What is maximum lifetime for service ticket?
The default maximum lifetime for user tickets and service tickets is 10 hours.
How do Kerberos tickets expire?
For security, Kerberos tickets expire pretty frequently — every 9 hours. For long jobs:
- Make a directory for yourself called /mnt/nokrb/yourusername and run “chmod 744” on that directory to restrict its access to you alone.
- Put everything your program needs in that directory, and cd into it before you run qsub.
What type of protocol is Kerberos?
Kerberos is a network authentication protocol. It is designed to provide strong authentication for client/server applications by using secret-key cryptography. A free implementation of this protocol is available from the Massachusetts Institute of Technology. Kerberos is available in many commercial products as well.
What port does NTLM use?
NT LAN Manager ( NTLM ) is the default authentication scheme used by the WinLogon process; it uses three ports between the client and domain controller (DC): UDP 137 – UDP 137 (NetBIOS Name) UDP 138 – UDP 138 (NetBIOS Netlogon and Browsing)
What is Kerberos and how it works?
Kerberos is a computer network security protocol that authenticates service requests between two or more trusted hosts across an untrusted network, like the internet. It uses secret-key cryptography and a trusted third party for authenticating client-server applications and verifying users’ identities.
What is SPN?
A service principal name ( SPN ) is a unique identifier of a service instance. SPNs are used by Kerberos authentication to associate a service instance with a service logon account. This allows a client application to request that the service authenticate an account even if the client does not have the account name.
What is MSSQLSvc?
SPN Formats MSSQLSvc is the service that is being registered. <FQDN> is the fully qualified domain name of the server. <port> is the TCP port number. <instancename> is the name of the SQL Server instance.
How do I set up SPN?
The steps to follow to configure an SPN account for an application server are:
- Assign the SPN to the Active Directory account using the setspn command.
- Repeat this command for any number of SPN to the same account.
- Generate a keytab file for the user account.
