slapd already strips DSA-specific attributes before sending a syncrepl entry. memberOf is not marked in the schema as DSA-specific. This is working as designed.

IIRC attribute 'memberOf' was replicated in former releases. So it was not DSA-specific back then.

Then the behaviour was changed in a more recent OpenLDAP release. Nowadays each replica has to be configured with slapo-memberof performing *local* operations. Therefore I'd argue that 'memberOf' should be marked DSA-specific now since the *local* configuration is significant for its content. Note that there is no formal specification for attribute 'memberOf' at all.

I have deployments where most users are member of more than 10 groups, sometimes more than 20. So not sending 'memberOf' could save quite a lot of network traffic.

What are your objections against marking 'memberOf' as DSA-specific?

(I vaguely remember this being discussed before without result though.)

Additionally consider partial replication where only a subset of group entries is present on a certain consumer. One would not want to have 'memberOf' point to group entries not really existing on that consumer.

=> 'memberOf' is definitely DSA-specific.
