I have previously asked this question with no response 18 months ago, I would
still like some assistance I have configured multiple LDAPs in a Mirror-Mode
configuration and fronted by OpenLDAP in proxy mode. I understand that the list
contained in the DBURI attribute is used to define the backends, and all the
proxies are configured with the same list. I understand that first URI in the
DbURI attribute will be used unless this fails, in which case it will fall back
to the second URI. It will then keep on the second one until that one fails.
This seems fine for most failure cases, when all proxies recognise the same
failure. If communication fails between one proxy and the one backend LDAP and
doesn't affect all proxies, writes will now be directed to different backends
from different proxies. Is there some way to keep the proxies in-line or
recognise a failure on one proxy and force the others to change. Or is this not
needed?
