如何在Java中对AD进行身份验证

Question

    Hashtable<String, String> ldapEnv = new Hashtable<String, String>(11);
    ldapEnv.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT);
    ldapEnv.put(Context.PROVIDER_URL, providerUrl);
    ldapEnv.put(Context.SECURITY_AUTHENTICATION,
            SECURITY_AUTHENTICATION_SIMPLE);
    ldapEnv.put(Context.SECURITY_PRINCIPAL, principal);
    ldapEnv.put(Context.SECURITY_CREDENTIALS, credentials);
    return new InitialDirContext(ldapEnv);

-对用户进行身份验证

Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "LDAP://url/");

env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "domain\\user_name");
env.put(Context.SECURITY_CREDENTIALS, "password");

InitialLdapContext ctx = new InitialLdapContext(env,null);
boolean authenticated = (ctx != null) ? true : false;

-获取所有用户的姓名

public ArrayList<String> getAllUsers(LdapContext ctx) {
    ArrayList<String> users = new ArrayList<>();
    try {
        SearchControls constraints = new SearchControls();
        constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);

        String[] attrIDs = {"cn"};
        constraints.setReturningAttributes(attrIDs);

        NamingEnumeration answer = ctx.search("dc=example,dc=com", "(&(cn=*))", constraints);

        while (answer.hasMore()) {
            Attributes attrs = ((SearchResult) answer.next()).getAttributes();
            users.add(attrs.get("cn").toString().replace("cn:", ""));
        }

    } catch (Exception ex) {
    }
    return users;
}

-搜索特定用途

public String getUserName(String username, LdapContext ctx) {
    try {
        SearchControls constraints = new SearchControls();
        constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);

        String[] attrIDs = {"cn"};
        constraints.setReturningAttributes(attrIDs);

        NamingEnumeration answer = ctx.search("OU=Employees,OU=Users,DC=sub_domain,DC=domain,DC=com", "uid=" + username, constraints);

        if (answer.hasMore()) {
            Attributes attrs = ((SearchResult) answer.next()).getAttributes();
            return attrs.get("cn").toString().replace("cn:", "");
        } else {
            return null;
        }

    } catch (Exception ex) {
    }
    return null;
}
