[Samba] nmbd error: workgroup name is too long

I found a similar thread in this mailing list from a few years ago, but it looks like there was never a clear resolution. (https://lists.samba.org/archive/samba/2015-February/189450.html).

I’m fairly frequently receiving the following error in my logs:

Feb  5 11:16:22 hal nmbd[19333]: [2018/02/05 11:16:22.889584,  0] ../source3/nmbd/nmbd_workgroupdb.c:57(name_to_unstring)
Feb  5 11:16:22 hal nmbd[19333]:   name_to_nstring: workgroup name COOMBS         ^[ is too long. Truncating to

I’m running Samba 4.7.4 on FreeBSD 11.1. My smb4.conf file has the workgroup name as “COOMBS”, with NO trailing spaces. Here’s the complete configuration file:

	workgroup = COOMBS
	server string = Samba Server Version %v
	netbios name = HAL

	security = user
	encrypt passwords = yes
	passdb backend = tdbsam

	wins support = yes
	domain master = yes

	interfaces =
	bind interfaces only = yes

	path = /zraid/plex
	valid users = plex
	writable = yes
	browsable = yes
	read only = no
	guest ok = no
	create mask = 0666
	directory mask = 0755

In the prior thread, there was speculation of some invisible control character at play. I typed the above configuration file manually--with no copy/paste--so that should not be the case.

Note that the error only seems to appear if "domain master = yes” is set.

The netbios services do see to work—I just get my logs filled with these errors.

Any suggestions?
