我有以下 JNDI 代码来将新用户的密码生成到 Apache DS 中：

 private String digest(String algorithm,String password) throws NoSuchAlgorithmException {
        String r = null;
        byte [] b = null;
        MessageDigest md = MessageDigest.getInstance(algorithm);
        BASE64Encoder encoder;

        md.update(password.getBytes());
        b = md.digest();

        encoder = new BASE64Encoder();

        System.out.println(encoder.encode(b));

        r = encoder.encode(b);

        return r;
    }

此代码添加新用户：

 public User create(User t) throws PersistenceException {
     NamingEnumeration answer = null;
     Attributes matchAttrs = null;
     Attribute objectClass = new BasicAttribute("objectClass");

     try {
         matchAttrs = new BasicAttributes(true); // ignore attribute name case
         matchAttrs.put(new BasicAttribute("uid",t.getCommonId()));

         answer = getConnection().search(userContext, matchAttrs);

         if( ! answer.hasMore() )
         {
             matchAttrs = new BasicAttributes(true);
             objectClass.add("inetOrgPerson");
             objectClass.add("organizationalPerson");
             objectClass.add("person");
             objectClass.add("top");
             matchAttrs.put(objectClass);
             matchAttrs.put(new BasicAttribute("cn", t.getFirstName()));
             matchAttrs.put(new BasicAttribute("sn", t.getLastName()));
             matchAttrs.put(new BasicAttribute("givenName", t.getFirstName()));
             matchAttrs.put(new BasicAttribute("mail", t.getCommonId()));
             matchAttrs.put(new BasicAttribute("userPassword", diggest("MD5",t.getPassword())));                
              getConnection().createSubcontext("uid="+t.getCommonId()+","+userContext,matchAttrs);
         }
         else
             throw new PersistenceException("This user already exists.");

     } catch (NoSuchAlgorithmException ex) {
         throw new PersistenceException("LDAP exception creating user - Hash algorithm not found.");
     } catch (NamingException ex) {
         ex.printStackTrace();
         throw new PersistenceException("LDAP exception creating user.");
     }
     return t;
 }

当我调用此代码时，它会生成一个哈希 MD5（我将“MD5”作为算法传递），然后它在 Base64 中编码并返回要用于 LDAP（apacheds）服务器的新用户的密码。

然而，服务器总是创建用户并将“SSHA”作为创建用户的算法。我该如何解决？我尝试了很多选项都没有成功，现在我决定问一下。有没有办法告诉 LDAP 服务器密码是用特定的哈希编码的？

试试这个来添加一个用户...

当 LDAP 存储加密密码时，它以以下形式存储：

{MD5}<md5hashInBase64>

尝试"{MD5}"像这里明确添加：http: //andrew-stephanie.ca/ldap-md5-java

matchAttrs.put(new BasicAttribute("userPassword", "{MD5}" + digest("MD5",t.getPassword())));
