Given that there is no such thing as A B and C class networks the last
20 years or so, that is not really acceptable behaviour for any
software package today.

It was choosen to ensure that the skolelinux code network could
co-exist with other networks on the 10.* private segment as long as
they stayed away from the 10.0.2.0/23 subnet. /23 was selected to get
a reasonable amount of machines (ie around 500). In hin-sight, we
should have used /22 or /21 to match the larger sites. The idea when
we selected it was that sites needing larger subnet would have the
skill set to update the network settings, which proved to be partly
incorrect. :)

Using a full /16 network would make it impossible to co-exist with
existing networks using any of the 10.0.* addresses. But using a full
/8 is worse, and using /24 leave too few addresses in the backbone
network.

Fix Gosa to behave like software should have been working the last 20
years is the best option.
