Why doesn't he let him in the ball?

Question

linux

Good afternoon! We have Centos7.
Why doesn't it let users into the balls without a password? When you try to go to the balls, an authorization window appears.
smb.conf:
[global]
#
workgroup = Workgroup
security = user
#=========================== Share Definitions ===== =========================
[homes]
comment = Home Directories
browseable = no
writable = yes
#=========== ================= Share Definitions ==============================
