我正在尝试进行LDAP搜索,但它无法在我的Active Directory测试服务器上运行.我用这个代码：

#include <winldap.h>
...
LDAP* ld = ldap_init("AD-servername", 389);
int myVersion =LDAP_VERSION3;
ldap_set_option(ld, LDAP_OPT_PROTOCOL_VERSION, &myVersion);
ldap_connect(ld, NULL);
//ldap_simple_bind_s(ld, NULL, NULL); I tried using this line too. but got the same error
LDAPMessage *pMsg = NULL;
int retVal = ldap_search_s(ld, "dc=myDomain,dc=extension", LDAP_SCOPE_SUBTREE, "(samAccountName=testaccount)", NULL, NULL, &pMsg);
//retVal = 1 which is LDAP_OPERATIONS_ERROR

我究竟做错了什么？

解决方法:

除非另行配置,否则必须使用Microsoft Active Directory服务器的有效帐户名和密码进行绑定,否则将返回除a very small handful之外的所有查询的操作错误.

即：

ldap_simple_bind_s(ld, NULL, NULL);

需要替换为：

char *username = "cn=aUser,ou=Users,dc=myDomain,dc=extension";
char *password = "this is the password";
ldap_simple_bind_s(ld, username, password);
