smb2_get_error "Tree Connect failed with (0xc0000022) STATUS_ACCESS_DENIED" while using negotiate version 0311 to connect some linux servers.

[Arlen-LT]

I pull from commit d8c85a3. My code is:

    smb2_context* smb2 = smb2_init_context();
    smb2_set_security_mode(smb2, SMB2_NEGOTIATE_SIGNING_ENABLED);
    smb2_set_timeout(smb2, 3);
    int ret = smb2_connect_share(smb2, ip, share, userID, password);
    if(ret < 0)
    {
        Log("%s\n", smb2_get_error(smb2));
        smb2_disconnect_share(smb2);
        smb2_destroy_context(smb2);
        smb2 = nullptr;
    }

and the error message is Tree Connect failed with (0xc0000022) STATUS_ACCESS_DENIED.
I tried to use smb2_set_version(smb2, SMB2_VERSION_0302); or any other negotiate version below SMB2_VERSION_0311 and connect successfully.
Could someone give me some advice? Thanks a lot.

Access denied is an error from the server, it means that the user you authenticate as does not have permission to access the share.

When I set the negotiate version as SMB2_VERSION_0302, everything works well with the same server and the same share, this is just happening while using Anonymous.
For example, my server allows Anonymous have permission to connect.
And in the past, this means I can use any userID and password to connect the server, for example:
smb2_connect_share(smb2, ip, share, "123", "123")
but if I use SMB2_VERSION_0311, I can use any userID as well, but only with the password "", for example:
smb2_connect_share(smb2, ip, share, "123", "")
Only by this way can I access my win10 smb server. But my ubuntu smb server told me STATUS_ACCESS_DENIED.
