Parking Management Software

Parking at Schiphol Airport has never been this simple. We all know how much there is to organise before a holiday or business trip: the flights, the paperwork, the luggage. And it doesn't end when you arrive at Schiphol. You still have to find a parking spot, board the shuttle bus - often with heavy luggage - and then find your way on foot to the correct departure lounge. A time-consuming and exhausting affair. But there is a simpler way: with Park and Fly!

Greifswald University


In Greifswald we personally guided the IT department for two days. We helped them configuring Group-Office on an active-active cluster. The cluster consists of servers. Each server is equiped with 2 quad core processors and 24 GB of ram. The servers both run Apache, MySQL and an OSCFS2 clustered filesystem. This Group-Office installation hosts over 20.000 users. They maintain all their users in an LDAP directory so we configured Group-Office to use their LDAP directory for user authentication.

Secure Email Sync

The Rijksrecherche in the Netherlands uses Group-Office in the Hague with about 100 users. We developed PGP e-mail encryption for them and the SyncML plugin for synchronizing their mobiles.
