As announced at October’s IT Users Meeting https://it-dep.web.cern.ch/it-dep/ITUM/, managed machines are to be switched to use a new Kerberos realm for authentication. This will be triggered by the update of the lcm-profile package.
The change has been in desktop testing since mid December and will be transparent for the majority of users.
Although machines which do not receive this update can continue to use Kerberos for authentication, some users may be affected in the following areas, and will need to follow the FAQ linked below in order to resolve their problems:
- - Password free, Kerberized ssh login
- - Acrontab
- - Those using dual-boot operating systems
- - Other Kerberos related errors
If the problems described above are encountered, please check the FAQ page.
If you are concerned whether you might be affected, please follow the FAQ’s Testing section before the 02/02/11.
