Site '%2' is no longer manually configured in the registry as
covered by this LDAP server for non-domain NC '%3'. As a result,
site '%2' does not have any LDAP servers for non-domain NC '%3'.
LDAP servers in site '%1' have been automatically
selected to cover site '%2' for non-domain NC '%3' based on
configured Directory Server replication costs.
