| + | ===== With TLS(StartTLS) ===== | ||
| + | 有幾個要點: | ||
| + | * 使用ldap protocol。 | ||
| + | * 透過DefaultTlsDirContextAuthenticationStrategy讓client與server negotiate。 | ||
| + | * 由於會做hostname的verify，為了測試，所以我們先override去避掉它。 | ||
| + | * 做authenticate時，透過LookupAttemptingCallback讓它在連線完成後做search，以驗證密碼是否正確。 | ||
| + | <code java> | ||

| + | contextSource.setUrl("ldap://192.168.1.13:389"); | ||

| + | strategy.setHostnameVerifier((hostname, sslsession) -> { | ||
