nothing seems to be clear with the login processes
firstly I have some PCs where login works and others that are not.
after login in with EDir, in the properties of the ZCM Agent, the user has not logged in.
I can login to ZCM afterwards

All users (that I tested) can login to PCs that function.
On the bad PC when I login as a user in an OU without policies I'm not getting the ZCM login popup

I uninstalled the client and tried to reinstall
