Comment 5 for bug 1697817

Just a side note folks but there's two SMBv1's involved here and both are mentioned in this bug report.

There's the server part ( server min protocol ).

But there is also a samba client part ( client min / max protocol ) and that's where the fun starts.

Nautilus uses gvfs which uses libsmblient to "discover" samba servers on the network. The client max protocol is net to NT1 ( SMB1 ) for a reason. Set "client max protocol = SMB3" or "client min protocol = SMB2" and that discovery is broken. You can still access a host by name but you have to know it's name.

You can verify that yourselves by using the command smbtree. Run it and you will get a list of your hosts and their shares. Change the client min or max values to something other than NT1 and smbtree results in nothing.
