    c.auth_scheme,
    s.HOST_NAME,

ON s.session_id = c.session_id

 

A query to see if a connection is made with Kerberos or NTLM.
login_name together with host_name and program_name will identify the login.
auth_scheme will reflect what security protocol was used

  1. you forgot the comma like so:
    SELECT
    s.session_id,
    c.connect_time,
    s.login_time,
    s.login_name,
    c.protocol_type,
    c.auth_scheme,
    s.HOST_NAME,
    s.program_name
    FROM sys.dm_exec_sessions s
    JOIN sys.dm_exec_connections c
    ON s.session_id = c.session_id

    thanks & regards!
