Hello,

I need to add that this problem ain't just after installation.
When samba was installed it was working good - that why its hard for you 
to reproduce this problem.

#sudo samba-tool domain passwordsettings show
Password informations for domain 'DC=domain,DC=local'

Password complexity: on
Store plaintext passwords: off
Password history length: 24
Minimum password length: 7
Minimum password age (days): 1
Maximum password age (days): 42

If you need please provide me with information what log you need and how 
to collect it for you.

I can try to upgrade it with tar.gz from website but I really not sure 
how to transfer my database from Samba that I installed from Ubuntu Repo 
to the samba compiled by my own.
