‘client max protocol = default’ used to be ‘NT1’ in many Samba versions.
In Samba 4.3.0 they changed it to ‘SMB3_11’ but we are not on that version yet. By setting the value we are kind of enabling it with our version.
I’m sure that your server negotiatied down to SMB1. Unless ‘server min protocol = SMB2’ is set on your server this still happens.
I’m with bedub1
the most widely compatible bet is to just add:
client max protocol = SMB3
(doesn’t break browsing)
The safest/most secure bet would be to add these 3:
client ntlmv2 auth = yes client min protocol = SMB2 client max protocol = SMB3
(breaks browsing)
name resolve order = bcast ... just tested it, doesn’t bring back browsing when SMB1 is disabled.
