Hi,
I am using open ldap 2.4.8 with Berkeley DB 4.6.21 ( I haven't applied any patch to either open ldap or to Berkeley DB).

When I configure a slave process, the addition and modification of users get propogated from master to slave. But the deletion of users from the master do not get propogated. the slapd logs in the master show that user is getting deleted.

Logs needed and an example user please ;-)

I saw a old note "http://www.openldap.org/lists/openldap-bugs/200409/msg00001.html" which listed similar issue.

Not relevant as that's for 2.2.
