Answer 3

1. OpenLDAP or its derivatives. You just need to understand that AD is a very powerful software based on the LDAP protocol, it also rules computers, not only users. But OpenLDAP was originally created specifically for storing accounts, so in Linux you will have accounts in LDAP, and centralized server management through some other software: Chef / Puppet / Ansible / Salt.
2. Regarding puppet - if you are deploying from scratch, even if you have little experience, ansible is better - for normal use of puppet and chef you will have to deal with Ruby, and Ansible uses a simpler syntax for its scripts, and even on the servers themselves, except for ssh, yes bash doesn't need anything, no ruby ​​packages, unlike puppet and chef.
