我正在使用Nexus存儲庫管理器（nexus.sonatype.org）和開源LDAP插件（code.google.com/p/nexus-ldap/）以及我收到一個錯誤，指出使用了錯誤的協議版本（詳情如下）。所有插件都使用JNDI LDAP服務提供程序連接到我的LDAP服務器。如果您查看nexus.log文件中的堆棧跟蹤，則會在JNDI LDAP實現中的上下文初始化期間發生異常。所以我的猜測是，下面描述的問題不是由Nexus插件引起的，而是由於JNDI的錯誤使用或對LDAP認證的誤解。Nexus和LDAP - 根據OpenLDAP服務器驗證用戶時的JNDI問題
任何有關如何導致錯誤的猜測或想法都非常感謝！
什麼步驟會重現問題？
- 配置的Nexus使用使用的OpenLDAP的1.2.x服務器LdapAuthenticatingRealm - 爲此LDAP協議的版本2。
- 嘗試列出OpenLDAP-Server中的用戶並將它們映射到Nexus配置UI中的角色 - 完美地工作。
- 現在嘗試使用映射到角色的LDAP用戶成功登錄到運行的Nexus實例或進行身份驗證。
預期產量是多少？你看到了什麼呢？
嘗試登錄時，我收到錯誤消息「用戶名，密碼不正確或沒有權限使用Nexus用戶界面，請重試。」。在Nexus日誌文件中，當Sun的JNDI-LDAP實現（請參閱下面的日誌文件中的堆棧跟蹤）嘗試使用給定信息初始化上下文以便根據LDAP服務器驗證用戶時，會看到引發的異常。使用Nexus用戶界面的用戶查找工作正常，以及在驗證期間執行查找（請參閱下面的日誌文件）。
CommunicationException（「[LDAP：錯誤代碼2 - 版本不支持]」）中包含的錯誤消息指示使用錯誤的LDAP協議版本。我試圖明確使用協議版本2，因爲OpenLDAP 1.2.7-30版僅支持LDAP v2（公司環境 - 服務器版本不可協商）。我這樣做是通過檢查你的源代碼，添加「env.put（」java.naming.ldap.version「，」2「）;」到se.devoteam.nexus.ldap.NexusLdapContextFactory：52。沒有改變。
在測試期間，我通過瀏覽Sun源代碼時意識到，javax.naming.ldap.InitialLdapContext.InitialLdapContext（） - 方法所做的第一件事是將ldap協議版本設置爲「3」（javax.naming.ldap .InitialLdapContext：131）。儘管Java6文檔解釋了我使用的屬性（java.sun [dot] com/javase/6/docs/technotes/guides/jndi/jndi-ldap-gl.html＃version），並且JNDI-tutorial提到了這個解決協議版本衝突的正確方法（java.sun [dot] com/products/jndi/tutorial/ldap/misc/version.html）我想知道：在使用JNDI時，是否有明確使用LDAP協議版本2的方法作爲LDAP服務提供商？
接下來，我嘗試使用相當最新版本的OpenLDAP服務器（openldap2-2.3）作爲LDAP協議版本3請求的代理，將其委派給舊服務器。同樣的問題，同樣的例外。
