rsnapshot
by
Lee Lammert
There are thousands of way to backup files, but only a few that
efficiently manage revisions over time.

rsnapshot is standard tool in almost any distro repos that uses rsync and
ssh to backup files to a remote system, and also allows configuration of
any number of backed up versions, such as:

hourly
daily
weekly
monthly
yearly

Each of these [file] shapshots uses hard linking to efficiently save an
exact copy of the original system image at the time point it is created.

Be sure to tune in and see exactly how it works, how to setup, and
examples of systems in use.

LDAP
by Tyler Rudie
Abstract:
noSQL before it was a thing, Lightweight Directory Access Protocol was used to maintain collections of data. Mainly used for authentication and address books. This database is both flexible and frustrating. We will go over connecting to the service, available tools to manage the data, managing the services and considerations required when building a server and dealing with schemas along with an example server for participants to use..

LDAP (Lite-weight Directory Access Protocol) is a software protocol for enabling anyone to locate data about organizations, individuals and other resources such as files and devices in a network -- whether on the public Internet or on a corporate Intranet.

LDAP is a protocol, and Active Directory is a server. LDAP authenticates Active Directory – it's a set of guidelines to send and receive information (like usernames and passwords) to Active Directory.

Kerberos is used to manage credentials securely (authentication) while LDAP is used for holding authoritative information about the accounts, such as what they're allowed to access (authorization), the user's full name and uid.

Details will be published on https://www.sluug.org/ when available.
