Data Security Thanks to Multiple-Factor Authentication in UCS with privacyIDEA + SAML

How can companies make access to their networks and applications securer and more user-friendly at the same time? What’s behind the terms SAML, multiple-factor authentication and single sign-on in this context? Cornelius Kölbel, Managing Director of our partner NetKnights, took the time to explain these technologies to us and illustrate how you can use the multiple-factor authentication solution privacyIDEA and SAML to set up a secure network on UCS plus saving employees time when signing in.

Synchronisation between UCS and Microsoft Windows with Samba Active Directory

In “Fail-safe performance and load distribution thanks to LDAP replication” I focused on describing the UCS OpenLDAP directory service. Unfortunately, OpenLDAP is only of comparatively little help to me if I want to operate Windows systems in my network, as Windows doesn’t speak the standard-compliant LDAP protocol as a rule, but rather a particular dialect that Microsoft selected for its Active Directory. I would now like to explain which technologies integrated in Univention Corporate Server we can use to deal with this situation and go into more detail about the replication via listener/notifier for OpenLDAP, DRS replication for the Active Directory and the “Univention S4 Connector”, which synchronises between the two worlds.

The End of Linearity, git Implementation in Professional Services

git-ucs-branches-releases-commands_enWe have now been using git as the version control software for our projects in the Professional Services Team at Univention for a number of weeks and to great success. In this blog article, I want to give you a bit more information about our decision to employ git, report on our initial, recent experiences and provide a perspective of the aspects still requiring work. In doing so, I hope maybe to provide you with a suggestion or two for your own projects or that perhaps you will also have ideas for how we can implement our requirements even better using git.

TL;DR

  • Both the migration of SVN to git and the use of git as a tool in the productive workflow have gone very smoothly.
  • The challenges involved in the professional introduction are considerable, particularly with regard to the preparation of the coordinated workflow.

UCS 4.1: First Milestone Released
