Re: back-config delete support (syncprov overlay)

Agreed. The actual choice of error probably isn't too critical.
LDAP_UNAVAILABLE sounds fine.

while taking up some loose ends on my work on delete support for
back- config (enabled with -DSLAP_CONFIG_DELETE) I wondered how we
should deal with the deletion of the syncprov overlay when there
are active refreshAndPersist sessions. What errorcode should we
sent when closing such a connection? To me LDAP_UNAVAILABLE sound
like the best choice. LDAP_UNWILLING_TO_PERFORM might also be ok.
What about an unsolicited notification (RFC 4511, 4.4)?
Hm, yes. A "Notice of Disconneciton" might work as well. But that would
result in the client connection been taken down, which is probably not
desired. For syncrepl connections from slapd-consumers this might be ok.
But other LDAPSync clients might have other operations active on the same
connection which wouldn't be affected by the removal of the syncprov
overlay, I guess.
Returning an error just for the LDAPSync related Search seemed more
logical to me.
Also on the topic of deletes, we should start adding term_module() handlers to
the backends and overlays.
