Symptoms

Authentication Authority Provider creation failed!

Unable to add external authentication provider to authentication service [ ErrorMsg: POST failed with HTTP-ERROR: 400. Server Message: Could not parse server-response from json string, HTTPErrorCode: 400]
  • 用於新增外部 auth 的組態值似乎沒有問題。 
  • 啟用 AUTHC 偵錯會在 authc-server.log中報告下列訊息:
YYYY-MM-DDTHH:MM:SS DEBUG Resolved [com.emc.brs.auth.server.exception.LdapVerifyException: The verification of the configuration options for Ldap has failed. [ LDAP: error code 8 - 00002028: LdapErr: DSID-0C090276, comment: The server requires binds to turn on integrity checking if SSL\TLS are not already active on the connection, data 0, v2580 ]; nested exception is javax.naming.AuthenticationNotSupportedException
注意:未啟用偵錯的情況下,authc-server.log 檔案不會更新。
 

Cause

LDAP 伺服器上有一個非預設的安全性設定,可強制執行以 SSL 保護的所有 LDAP 驗證。

網網域控制站上的此原則為:「網網域控制站:LDAP 伺服器簽章要求」,如果設定為「需要簽署」連線,如果沒有設定為使用 SSL,則會失敗。

由於 LDAP 伺服器已設定為需要簽署通訊,因此 LDAP 伺服器會拒絕簡單的系結要求 (埠 389)。
