Airflow SambaHook authentication issue with SpnegoError and Kerberos

Apache Airflow Provider(s)

samba

Versions of Apache Airflow Providers

I am trying to connect to a Samba server in Airflow using the SambaHook class. The Samba server requires Kerberos authentication.

I have already defined a Samba connection in Airflow using the following parameters: Host,Schema and Extra {"auth": "kerberos"}

airflow connections add "samba_repo" --conn-type "samba" --conn-host "myhost.mywork.com" --conn-schema "fld" --conn-extra '{"auth": "kerberos"}'

I'm trying to use the SambaHook class in Airflow to connect to a Samba server. When I run my code, I get the following error:

Failed to authenticate with server: SpnegoError (1): SpnegoError (16): Operation not supported or available, Context: Retrieving NTLM store without NTLM_USER_FILE set to a filepath, Context: Unable to negotiate common mechanism

However, when I use smbclient to connect to the same server using Kerberos authentication from the Docker terminal, it works fine with the command: smbclient //'myhost'/'fld' -c 'ls "\workpath\*" ' -k

What I tried: I set up a connection to the Samba server in Airflow using the SambaHook class and tried to use the listdirmethod to retrieve a list of files in a specific directory.

What I expected to happen: I expected the listdir method to successfully retrieve a list of files in the specified directory from the Samba server.

What actually resulted: Instead, I encountered the following error message: Failed to authenticate with server: SpnegoError (1): SpnegoError (16): Operation not supported or available, Context: Retrieving NTLM store without NTLM_USER_FILE set to a filepath, Context: Unable to negotiate common mechanism
