DLP User Groups based policies do not work properly on EMail Prevent
I need to create a policy that, on Email Prevent, triggers when a user belonging in a certain AD Group sends out an email containing PAN numbers.
I put the rule "Sender/User based on a Directory Server Group" in my policy, but the behaviour is unpredictable, sometimes it works, sometimes it does not.
I checked LDAP attributes, in both cases, the "email" field is set correctly.
Has anyone had the same problem?
