Active Directory at school
The Challenge
Active Directory or other directory services at school offer many advantages, e.g. users do not need to set up their passwords individually on each computer.

For the sake of simplicity, the import takes place from a comma-separated file. This is product independent and no special drivers or interfaces are needed.
Furthermore, comma separated files can be generated from any data source.

In fact, semicolons are often used as separators.
