As part of our ongoing efforts to enhance the HPC clusters at the University of Geneva (Unige), we would like to inform you about upcoming changes regarding the authentication methods for accessing the HPC frontend.
The objective of this operation is to transition to a “full” LDAP authentication system, which directly and dynamically relies on Unige’s IT directory, thereby improving the security of our clusters.
