So this should succeed, and yet it fails. Need to figure out why.

I dug into this further with Ondrej, and the issue is that ppolicy was never updated to work correctly in a delta-sync MMR environment. ppolicy on the receiving server currently has logic to test if it is a shadow (i.e., replica) and if so, change its behavior. But there is no similar logic to handle the case if the receiving server is an MMR node (i.e., a shadow and a master).

The following 3 changes to the code base for ppolicy would alleviate this issue and other potential issues:

• test we're a replicated op, not just on shadow

The patch is available here: https://github.com/mistotebe/openldap/tree/its8927

• issue MOD_REPLACE (concurrent binds could have cleared that attribute on

the other servers)

• expect MOD_REPLACE as well as MOD_DELETE on replicated ops

Maybe not exactly required since ppolicy will actually treat these deletes as soft deletes if needed.
