I wanted to add, that one database is empty when I start and the other has only some data. But with master/slave this is no problem, so I think it should also work for master/master, doesn't it?
I retried with a patched version with these patches: < http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=patch;h=8e7af6331ec2d0edaeb203b1c52d4016bc2bbcbf > < http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=commitdiff;h=d4b3c2af6a61678060ef417b59bd63a36ec15c13 > < http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=commitdiff;h=eace24ef33dfae071b9450866d0ef5b0d3ad6d7f > Unfortunately the problem still persists. Could at least anyone confirm that the configuration is correct? Then I can at last stop searching for a error I possibly did and accept that OpenLDAP with Master/Master (delta-syncrepl) for Windows simply does not work.
