samba - Jan 2019 - nobody account already in shared directory write list, can not write

Hi all,
	Now I have a directory shared with anonymous account nobody. And I have add it
to the write list of my share.
	When i mount it by windows 10, I create a sample file name test.txt, I check it
in backend file system looks like this:

		-rwxr—r— 1 nobody nobody test.txt

	 I can delete/create/rename a file, but can not write into it. Please help me.

	My samba version is 4.4.4, samba server is CentOS, and the directory mode is
777, my smb.conf as below:
[global]
	server string = Samba Server Version %v
	log file = /var/log/samba/log.%m
	browseable=no
	guest ok = no
	security = user
	map to guest = bad user
	load printers = no
	printing = bad
	printcap name = /dev/null
	disable spools = yes
	workgroup = HIKNAS
	netbios name = fs01

[gltest]
	comment = 
	path = /mnt/gltest
	public = yes
	writeable = yes
	valid users = nobody
	write list = nobody
	directory mask = 0755

Try it like this:

[global]
	workgroup = HIKNAS
	netbios name = fs01
	security = user
	server string = Samba Server Version %v
	log file = /var/log/samba/log.%m
	map to guest = bad user
	load printers = no
	printing = bad
	printcap name = /dev/null
	disable spools = yes

[gltest]
	path = /mnt/gltest
	browseable=no
	guest ok = yes
        read only = no
	guest only = yes

Hi, 

Thanks for your help. I have tried what you say, and i works. 

But it’s very strange that i can not reproduce this using my old config.

There is more detail about this:
	I have 4 standalone samba server with same samba software and smb.conf. 
	I got the problem at the same time in all 4 server, and when i change smb.conf
as you suggest on one of them,
	the problem disappear on other 3 server with old smb.conf.

So I wanna know do you have some idea about this?
