Dear Devels,
samba-4.2.3-10.el7.x86_64
# vim smb.conf
[global]
workgroup = MYGROUP
server string = Samba Server Version %v
log file = /var/log/samba/log.%m
max log size = 50
security = user
passdb backend = tdbsam
load printers = yes
cups options = raw
server signing = auto
server signing = mandatory
[homes]
comment = Home Directories
browseable = no
writable = yes
[printers]
comment = All Printers
path = /var/spool/samba
browseable = no
guest ok = no

[test]
comment = samba share
path = /test
guest ok = no
write list = @CAT
browseable = yes
create mask = 0755

blocking locks = no
block size = 4096
Here CAT is local group.
# id catuser
uid=5060(catuser) gid=1033(CAT) groups=1033(CAT)
For my customer, When 200+ User access /test (using catuser). Some users can
access share but blank contents.
In smb logs:
For passing user:
01hwcl858826 (ipv4:10.29.180.45:60627) connect to service test initially as user
catuser (uid=5060, gid=1033) (pid 5286)
check_reduced_name: . reduced to /test
unix_mode(.) returning 0744
check_reduced_name [CAT/CAT_658/PROJECT/EXTERIOR/DG] [/test]
For failing user:
01hw1027178 (ipv4:172.29.208.178:54638) connect to service scratch initially as
user catuser (uid=5060, gid=1033) (pid 28686)
check_reduced_name: . reduced to /test
unix_mode(.) returning 0744
checking for home directory test.ws <http://scratch.ws/> gave (NULL)
checking whether test.ws <http://scratch.ws/> is a valid printer name...
Query:
1. Is there a limit on max number of connections to share? There must be
what's the max?
2. Is using force user, force group good option here?
3. Is there limit on max number of files opened, Can this issue be related to
this?
4. Why in failing case it checking 'home dir, Printers'?

It looks like they are all using the same username to connect to the share, is this correct ? If it is correct, are they all using the same password ? Is this standalone server in an AD domain ? Do the clients that don't work have NTLMv1 turned off ? Rowland

This i need to enquire, But I think No. Beacause issue happens randomly on any of clients when connections reaches > 200 or so. > > Rowland >-- Thanks Amit Kumar !!If you stumble, get back up.
