This kinda leads me to thinking we should implement ACIs management
within the DSLdapObjects like this (probably specific to a particular
subclass, to a degree). One that would take care of this added
requirement for objectclass ACIs because of hidden .filter's behavour.
Because that is currently really hard to be understood at a first
glance, or second.

Ummm, that’s not what I’m saying? I’m saying that you may *only* be giving access to the
mail attribute, so as a result when the .filter generates and expands to
(&(objectClass=account)(mail=*)), the objectClass is denied on the searcch, causing
the test to fail (to prevent disclosure).
That’s why I suggest changing the aci to allowing mail AND objectClass, and testing
again. I think this is atn aci issue not a python, and I’d like to rule out that first.
