Microsoft open system logon with opensource PKI

Open source software can create some problems related to costs and organization. We faced the issue of digital authentication in Microsoft operating systems, with reference to the certification authority open source. We have tried to solve this problem analysing the Windows requests and forcing them on the PKI configuration file. Finally, a user's interface allows the system administrator to operate with the largest flexibility. The experimentation carried out in a business network environment has given the best results.
