I got some flags in my es_WCSadmin_db.txt related to wcscadmin but I don't have wcscadmin on my server... how to enable it or where to get a wcscadmin that works with such flags?

This one is different and you have to replace everything in the admins file:

P.s: I'm not talking about default wcsadmin but wcscadmin
