Weekly Changes – 08/04/2024

This week saw some work on the ED layer support for a simple personal desktop build using GDM rather than LightDM.

Here are the details of all the notable changes…

GDM and PAM Trimspaces

The lcfg/options/gdm.h header will now use pam_trimspaces to strip off whitespace surrounding usernames in the same way as LightDM does. Simply define the GDM_TRIMSPACES cpp macro before including the header file.

ED Layer Central Authorisation Usernames

The ed/options/auth/central-auth/sssd.h header configures sssd to also accept usernames in the form or uun@ED.AC.UK, returning the LDAP user with uid=uun as it would for a bare username. This matches the behaviour of the Your University Login (EASE) web single sign on and MS Windows clients.

ED Site Default Definitions and SSH

The ed/options/auth/central-auth/sssd.h header now allows the LCFG layer to configure tcpwrappers for sshd via the _SSH_FROM cpp macro. It no longer defines _NO_DEFAULT_TCPWRAPPERS.

Changes to headers and package lists

Members of the Informatics Computing team can browse all the changes to the headers and package lists.
