我正在遷移一個通過 EWS 實作用戶身份驗證的 Redmine 插件。該插件在 Ubuntu 桌面 VM 上運行的 Redmine v4.x 上進行了測驗，并且作業正常（可以判斷給定的憑據是否有效）。
該插件的主要部分是：
require 'viewpoint'
include Viewpoint::EWS
defaultServer = 'https://company.mail.server/ews/exchange.asmx'
defaultEmailDomain = '@domain.com'
emailAddress = "username" defaultEmailDomain
password = "password"
client = Viewpoint::EWSClient.new(defaultServer, emailAddress, password)
result = client
begin
client.folders
rescue
result = 'nope'
end
puts result
此代碼適用于以前的 VM 和我的 Windows 機器，但在我的新 Ubuntu Server 22.04 VM 上回傳“不”。
我還嘗試使用可在新 VM 上運行的 exchangelib 在 Python 中撰寫一個版本。IMO 表明該問題與 Ubuntu Server 可能具有的任何網路限制無關。
有什么建議么？
更新：
按照理查德的建議，我保存了救援捕獲的錯誤訊息。將錯誤型別更改為 EwsError 后，我得到以下資訊：

附加資訊：成功運行用戶身份驗證的 Windows 測驗機器具有與上述相同的 gem 版本。唯一的區別是 Ruby 本身的版本（Ubuntu 上為 3.0.2p107，Windows 上為 3.1.2p20）。
更新：
根據此差異修改 openssl.cnf啟用加載舊提供程式后，該插件現在可以作業。
