出了个奇怪的现象！！
用ldapadd -x -f admin.ldif -D 'cn=Manager,dc=zhaohengtai,dc=com' -W
提示：ldapadd:Invalid syntax(21)
      additional info: objectClass:value #2 invalid per syntax
可添加root.ldif ,vmail.ldif ,bsdlife.ldif base_ou.ldif 时：都成功的呀！
＃less root.ldif
dn: dc=zhaohengtai,dc=com
ObjectClass: dcObject
ObjectClass: organization

我的添加顺序是这样的，是添加顺序的问题吗？还是别的问题？
