Hi john,
We added checks before you can create an awareness trainings because many times LDAP settings differ and that creates a bit of chaos.
That guide explains exactly what is the error most people will get when using inconsistent LDAP settings.
You can do this with LDAP “filters” (i personally think LDAP is old stuff so is hard to get complex queries working) or using the “ignored users” from the awareness program.
Check the post above, it has the cheatsheet i use when helping customers debug ldap trouble.
I hope any of this makes any sense and helps?
