I'm not sure I understand "user modification requests" well. By user, do you mean the person who manipulate the directory or an object of "type" user ?
This term is used for normal LDAP modify requests coming from a LDAP client external to slapd.
If I have memberof overlay activated and it changes the uid's memberof attribute, isn't it a user modification request (by memberof overlay) ?
Every modification done by an overlay is internal.
I've tested refint another way. I removed the user (identified by uid) from the directory. When the user is deleted, refint_nothing works and replaces the last member with the placeholder (I also have some debug information in logs). I thought that refint_nothing would also work when a modification is done on one of refint attributes.
In this case slapo-refint's own modification is internal and therefore refint_nothing applys. But it does apply when the modification comes from an external LDAP client.
Thinking about the empty-groupOfNames-problem some more I consider to define a cn=dummy value to be always present in groupOfNames entries and apply val-based ACLs to make it invisible and unremovable for normal clients (even the ones maintaining the groups).
