The problem still alive.

Today Win8* cannot access to server, into log I see this message:

> Oct 22 09:27:11 s-backup smbd[32645]: STATUS=daemon 'smbd' finished starting up and ready to serve connectionssmb_signing_good: BAD SIG: seq 2
> Oct 22 09:27:11 s-backup smbd[32645]: [2015/10/22 09:27:11.575613,  0] ../source3/smbd/process.c:505(receive_smb_talloc)
> Oct 22 09:27:11 s-backup smbd[32645]: receive_smb: SMB Signature verification failed on incoming packet!

seem a winbind problem, if I restart it, all work fine

Someone have some other suggest?

This is my smb.conf:

Load smb config files from /etc/samba/smb.conf
rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384)
Processing section "[homes]"
Processing section "[backup]"
Loaded services file OK.
Server role: ROLE_DOMAIN_MEMBER
[global]
	workgroup = STUDIO
	realm = s-backup.studio.it
	server string = Samba Server Version %v
	security = DOMAIN
	passdb backend = tdbsam:/etc/samba/account.tdb
	log file = /var/log/samba/log.%m
	max log size = 50
	server signing = required
	load printers = No
	printcap name = /dev/null
	local master = No
	domain master = No
	wins server = 192.168.50.1
	winbind enum users = Yes
	winbind enum groups = Yes
	winbind use default domain = Yes
	idmap config * : range = 1000000-9999999
	idmap config * : backend = rid
	printing = bsd
	cups options = raw
	print command = lpr -r -P'%p' %s
	lpq command = lpq -P'%p'
	lprm command = lprm -P'%p' %j
	store dos attributes = Yes

[homes]
	comment = Home Directories
	read only = No
	browseable = No

[backup]
	comment = Cartella con Backup
	path = /backup2t/rsnapshot
	valid users = @STUDIO\grpbackup
	force user = root
	force group = root
	guest ok = Yes

Many thanks
