Can't connect SMB drive on MacOS

[danajuratoni]

Testing this using a MacBook with Monterey 12.3.1 as a network drive, with SMB File Sharing enabled.
And a runtime environment with MacOS Monterey 12.4, Python 3.9.13.

I enabled logging of SMB.SMBConnection in the Network Drive client and see the following error:

Username and password are correct and I'm able to connect to the drive via Finder and via command line using mount, so the issue in not on the drive side.

Already tested alternatives such as without direct TCP & port 139, and NTLM v1 but no success.
Seems to be a config issue others experienced too while using this library miketeo/pysmb#193.

What's the latest on this @praveen-elastic ?

Hey @serenachou, We tried various ways for connecting to a shared folder on Mac. I am attaching a doc describing all the explored approaches. I am still working on finding a proper resolution for this issue. I'll update you for the same. https://docs.google.com/document/d/1aGYiZbtN-t-M_Wz58ywI0U_PjJKnDIGMkdbzrP6iTn4/edit?usp=sharing

@praveen-elastic thanks for the link and the approached tried. Please update us in tomorrow's sync on the progress.

Revisit this in the version added to the updated connector framework in scope of #24 cc @danajuratoni
