我在linux系统下使用ldapsearch命令获取win2003搭设的AD域，如果里面包括姓名，获取的值为看起来像是base64加密的信息，而且使用c解码后，显示为乱码
linux下执行：
ldapsearch  -LLL -l 2 -h 172.16.1.125 -b "dc=testldap,dc=billion,dc=com" -x -D 1 -w 1234567 objectClass=user

结果：

objectClass: top
objectClass: person
objectClass: organizationalPerson
objectClass: user
cn: Administrator

其中sAMAccountName:后面应该是中文，然而看起来我获得是base64加密后的编码
请问是否中文一定是用base64加密后送过来，还是其他加密方法？
另外我要把该信息用c处理，应该如何转化为utf8或者gb2312编码？
不甚感激！！！！

显示的结果：中文字符转换为utf8再用base64
iconv命令和函数可以处理

可以用ldap其他工具找出具体中文，然后用iconv -f gb2312 -t utf8 file.txt >b.txt
然后再找个base64在线转换b.txt的查看下，是否跟ldapsearch显示结果一致
