我在Tomcat server.xml文件中的Tomcat安全领域中引用LDAP。但是我收到一个不寻常的错误：Tomcat没有启动，进入日志我发现它无法连接到localhost：389 - Tomcat的默认LDAP URL。
但是，Tomcat配置为指向不同的URL（不是同一台机器的外部URL;完全不同），如下所示：
<Realm className="org.apache.catalina.realm.JNDIRealm" debug="99"
connectionURL="ldap://XXX.XX.XX.XXX:389"
userSubtree="true"
userPattern="(cn={0},ou=XXXXXXXX,ou=XXXXX,o=XXX)"
roleBase="ou=XXXXXXXX,o=XXX"
roleName="cn"
roleSearch="member={0}"
connectionName="cn=XXXXXXXX,ou=XXXXXXXX,o=XXX"
connectionPassword="XXXXXXXX"/>
基本上我不知道它为什么还在看localhost：389。如果以前有人遇到过这个，我会感激一些帮助！我用谷歌搜索了一段时间但是当人们将错误粘贴到页面中时，似乎没有很多答案。如果有人有任何建议，我将不胜感激。
这是日志文件：

尝试添加'alternateURL'属性，其值与connectionURL相同。出于某种原因，当我遇到类似的问题时，这对我有用。
答案 1 :(得分：2)
我知道这是一个非常古老的帖子，但我最近遇到了这个问题，问题在于我将我的JNDIRealm嵌套在LockoutRealm中。
通过将JNDIRealm作为我的顶级领域我不再有描述的问题。如果你确实需要锁定领域，这个解决方案没有帮助。
