At work, we use Quotas on our User’s Homedrives. There is a default Quota on the Shared Homedir folder. There used to be multiple of these folders, and when a user got a larger Quota, the homedir had to be moved + the user’s account hat to be altered accordingly. Since it is a mapped drive, which is also offline synced on the Notebooks, this lead to quite some administrative work, if the user got a larger Quota.

So I’ve decided to set the quota using Active Directory groups + Powershell. This runs daily in a scheduled task.
Limitation: I do not remove non default quotas, if a user should get a larger Quota for a limited period, the Quota is not automatically removed. Could be automated, but is not a valid scenario in our case.

# Der übergeordnete Userhome Ordner hat die default Quota
# Die User welche in einer entsprechenden Quota-Gruppe sind erhalten die der Gruppe zugehörige Quota
# Entfernen aus der Gruppe führt nicht zur Entfernung der Quota!
