How to quickly delete all users in ACS for Windows 4.0

[magurwara]

Is there a way to quickly delete all ACS for Windows 4.0 users? It is not in the GUI and I believe CSUtil would need to be utilized but CSUtil does not accept the '*' for deletion. I tried to use '*' as a catch all.

csutil -n should nuke the database... but wipes SPCs and group settings also.

So instead try this:

csutil -d (to create a backup!)

csutil -g (to dump groups & spcs only)

csutil -n (to nuke everthing)

csutil -l group.txt (to reload groups)

Please test on a non-production server first - to ensure its works as expected.
