Manually enroll SLES12 systems to Redhat IdM

RHEL and Ubuntu systems leverage the ipa-client software to easily enrolled them to a Redhat IdM system. Unfortunately SLES12 lacks the required packages. Nevertheless, SLES12 systems can be enrolled manually. This article is about how to achieve this. Why using IPA for SLES systems? Most organizations are not pure RHEL or pure SLES shops, the reality shows a heterogeneous mix of Linux distributions in corporate data centers. It makes sense to use the same authentication and authorization system to manage ….Read More

A lot of RHEL users have some SLES systems running and so are SLES users running some RHEL systems. Some companies have additional systems ….Read More

SUSE Manager based on Fedora Spacewalk

Now it is clear, they are using Spacewalk as there source for its own product. Spacewalk is no longer just the upstream of RHN Satellite, but ….Read More

Rumors about Novell and Suse Linux

There have been a lot of rumors that Novell will be sold. Latest rumors are that the Linux parts of Novell (former SuSE) will be split off and sold separately. Since that got public, there are even more rumors: Which company will buy the Linux part of Novell? Red Hat: Very unlikely, since the Monopolies and Mergers Commission in the EU and USA will most likely disagree because RHEL and SLES are already some kind of “duopoly”. Microsoft: No way ….Read More
