错误代码：
application.properties
spring.ldap.urls=ldap://10.110.38.162:389
spring.ldap.username=cn=admin,dc=yaobili,dc=com
spring.ldap.password=123456

LdapTest
@Testpublic void listUsers() throws NoSuchAlgorithmException {AndFilter filter = new AndFilter();filter.and(new EqualsFilter("objectClass", "inetOrgPerson"));List<LdapUser> users = ldapTemplate.search("ou=Develop,ou=Hytera,dc=yaobili,dc=com", filter.encode(), new LdapUserAttributeMapper());for (LdapUser user: users ) {System.out.println("user: " + user);System.out.println("userPassword:" + user.getUserPassword());System.out.println(verifySHA(user.getUserPassword(), "Eadmin123456"));}}
疑惑：32错误码对应dn设置不对，但是我感觉不出来哪里不对啊，感觉spring.ldap.base和ldapTemplate.search都设置了正确的dn 啊，而且"ou=Develop,ou=Hytera,dc=yaobili,dc=com"这个dn就是我要查询账户所在的完整dn路径啊，不信看图。
错误原因：spring.ldap.base和ldapTemplate.search是有传递行的（你可以理解为拼接的效果，一因此不能设置一样的否则就乱套了，找不到了）。这易错点特别操蛋，因为根本别人的博客找不到还有这个规则说明，上来就是给你贴配置类文件和代码，然后照抄运行就报错，关键他们也不贴运行结果，我就只能挨个尝试去试错。
解决方案：
- 如果
spring.ldap.base设置了spring.ldap.base=“ou=Develop,ou=Hytera,dc=yaobili,dc=com”，那么search方法构面跟的就应该是空字符串“”）
spring.ldap.base=ou=Develop,ou=Hytera,dc=yaobili,dc=com
List<LdapUser> users = ldapTemplate.search("", filter.encode(), new LdapUserAttributeMapper());
- 如果
spring.ldap.base设置了spring.ldap.base=dc=yaobili,dc=com，那么search方法构面跟的就应该是"ou=Develop,ou=Hytera"
spring.ldap.base=dc=yaobili,dc=com
List<LdapUser> users = ldapTemplate.search("ou=Develop,ou=Hytera", filter.encode(), new LdapUserAttributeMapper());
