Is SQL Server using Kerberos?
When we talk about Kerberos authentication protocol and SQL Server security we should understand that this is only applicable to the Windows Authentication method. SQL Server logins do not use Kerberos as they are not authenticated with the Active Directory domain.
What is NTLM and Kerberos authentication?
Like NTLM, Kerberos is an authentication protocol. NTLM relies on a three-way handshake between the client and server to authenticate a user. Kerberos uses a two-part process that leverages a ticket granting service or key distribution center. Another main difference is whether passwords are hashed or encrypted.
What uses NTLM authentication?
Windows Challenge/Response (NTLM) is the authentication protocol used on networks that include systems running the Windows operating system and on stand-alone systems. The Microsoft Kerberos security package adds greater security than NTLM to systems on a network.

What is the difference between NTLM and LDAP authentication?

How to use Kerberos integrated authentication in SQL Server?

See Setting the Connection Properties for more information on connection properties.
Why is MS SQL Server using NTLM authentication?
It’s because I was connecting to the SQL Server locally, from the same server that hosted SQL Server. When I connect from another machine on the network, the authentication mechanism used is Kerberos, as expected. SQL Server will always use NTLM if connecting locally.
Where to find Kerberos string in SQL Server?
