我目前使用的是Ubuntu 10.04（我已經在RHEL 5.x上設置了它，但在Ubuntu中配置方式不同）。當節點脫機時，OpenLdap主/主複製停止
無論如何，起初我想我有一切工作。當我對ldap01進行更新時，我立即看到了ldap02上的更改。但是，如果我取下ldap02（或01）上的slapd，並將LDAP條目添加到ldap01中，則將ldap02的slapd進程重新聯機，我從來沒有看到在slapd在ldap02上關閉時創建的條目。新條目不斷ldap01和ldap02和長期之間propigate爲兩個服務器具有slapd進程正在運行，但是當slapd的下跌對ldap02創建的條目從未傳播到02
這裏是我的CONFIGS和LDAP版本：
II的slapd 2.4.21-0ubuntu5.7 OpenLDAP服務器（slapd的）

升級了我的OpenLDAP版本和我的問題他們走了。 –
