我們想測試並希望切換到開放交換（來自微軟交換）。我們會在支援下購買它，但現在我們正處於測試階段，所以我需要你的幫助。
一直彈出以下錯誤，無法登入：
file: /var/log/open-xchange/open-xchange.log.0
com.openexchange.exception.OXException: SRV-0001 Categories=TRY_AGAIN Message=
'The required service com.openexchange.authentication.AuthenticationService is temporary not available.
Please try again later.' exceptionID=1870517054-3
以下內容來自：/opt/open-xchange/etc/ldapauth.properties
java.naming.provider.url=ldap://contoso.com:389/dc=contoso,dc=com
java.naming.security.authentication=simple
uidAttribute=cn # alternative uidAttribute=sAMAccountName has also been tried
baseDN=ou=users,dc=contoso,dc=com
adsBind=true # false has also been tried
bindOnly=true # false has also been tried
ldapScope=base # subtree has also been tried
# searchFilter # is this needed?
bindDN=readOnlyAdmin,ou=admins,dc=contoso,dc=com
bindDNPassword=secret
驗證 ldap 套件處於活動狀態：
root@openexchange /o/open-xchange# sbin/listbundles |grep ldap
bundlename: com.openexchange.authentication.ldap status: ACTIVE
如果我在網上搜尋它，我會發現一兩個結果，具有相同的問題，但他們的解決方案（例如https://forum.open-xchange.com/archive/index.php/t-7634.html）不適合我。
我希望有人能讓我走上正確的方向。
系統：
- CentOS 7
- SELinux = 停用
- OpenExchange 安裝自http://software.open-xchange.com/products/appsuite/stable/backend/RHEL7/
- Active Directory 是基於 Windows 2008 R2。
