The KEK Computing Research Center provides various IT services, such as email, WiFi network, data analysis system, etc. A user submits paper application forms to apply those services. Moreover, some services require endorsement by a KEK staff. From the Computing Research Center point of view, we receive applications from many users every day. These forms are checked, processed, and handed out...

The number of BYOD devices at CERN is growing and there is interest in moving from a centrally-managed model to a distributed model where users are responsible for their own devices. Following this strategy, new tools are needed to distribute and - in case of licensed software - also manage licences for applications provided by CERN. Available open source and commercial solutions were...
