我正在尝试使用 Spring LDAP 和 Spring security 进行身份验证，然后查询我们的公司 LDAP。我设法使身份验证工作，但是当我尝试运行搜索时，我总是得到以下异常
为了执行此操作，必须在连接上完成成功的绑定
经过大量研究，我有一个理论，即在我进行身份验证之后，在我可以查询之前，我需要绑定到连接。我只是不知道什么和如何？
顺便提一下 - 我可以使用 JXplorer 成功浏览和搜索我们的 LDAP，所以我的参数是正确的。
这是我的 securityContext.xml 的一部分
<security:http auto-config='true'>

<security:intercept-url pattern="/reports/**" access="ROLE_USER" />

LdapAuthenticatorImpl这是执行身份验证的代码片段。这里没问题：
@Override
public DirContextOperations authenticate(final Authentication authentication) {
// Grab the username and password out of the authentication object.
final String name = authentication.getName();
final String principal = this.principalPrefix + name;
String password = "";
if (authentication.getCredentials() != null) {
password = authentication.getCredentials().toString();
}
if (!("".equals(principal.trim())) && !("".equals(password.trim()))) {
final InitialLdapContext ldapContext = (InitialLdapContext)
this.contextFactory.getContext(principal, password);
// We need to pass the context back out, so that the auth provider
// can add it to the Authentication object.
final DirContextOperations authAdapter = new DirContextAdapter();
authAdapter.addAttributeValue("ldapContext", ldapContext);
this.employee.setqId(name);
return authAdapter;
} else {
throw new BadCredentialsException("Blank username and/or password!");
}
}
EmployeeDao这是我徒劳地尝试查询的另一个代码片段：
public List<Employee> queryEmployeesByName(String query)
throws BARServerException {
AndFilter filter = new AndFilter();
filter.and(new EqualsFilter("objectclass", "person"));
filter.and(new WhitespaceWildcardsFilter("cn", query));
try {
// the following line throws bind exception
List result = ldapTemplate.search(BASE, filter.encode(),
new AttributesMapper() {
@Override
public Employee mapFromAttributes(Attributes attrs)
throws NamingException {
Employee emp = new Employee((String) attrs.get("cn").get(),
(String) attrs.get("cn").get(),
(String) attrs.get("cn").get());
return emp;
}
});
return result;
} catch (Exception e) {
throw new BarServerException("Failed to query LDAP", e);
}
}
最后 - 我得到的例外
org.springframework.ldap.UncategorizedLdapException:
