[Samba] User accounts locked for no reason

[Ricardo Pardim Claus]

Dear,Some user accounts are being blocked, without the user exceeding error attempts. It is currently defined as 4 attempts.Looking at the Samba4 Wiki, I changed the settings in smb.conf, in order to raise the log level and try to find out more details about the block, such as where there was a block due to access attempts.While looking at the log, I got a test account, made a mistake in the password until I locked the account. I didn't see any information in the log regarding the lock.
My smb.conf:
log file = /var/log/samba/samba.loglog level = 5 full_audit:1@/var/log/samba/audit.log auth:5 winbind:5 auth_audit:5 dsdb_password_audit:3 passdb:3max log size = 400000
Could anyone give me any tips?Thanks!
