[Samba] SAMBA4 and unix extensions

[Luis Recuerda]

I am using a samba 4.1.9 as a file server for linux and windows clients.

I have discovered that I cannot use "unix extensions" with the linux
clients, I get "operation not supported" errors. Using wireshark I can see
that the server sends STATUS_INVALID_LEVEL response to "Query File Unix
Basic" request.

I have found in this mailing list this message of Andrew Bartlett:

Four years ago samba4 could not serve "unix extensions". Is this problem
still present in current version?

best regards,
