如何使用Java连接到Active Directory
我正在使用Weblogic,Ejb3.0。Java 1.6
我需要通过Java代码访问Active Directory。我读了几种方法(Kerberos,LDAP)
有人可以建议我这样做的舒适方式吗?在哪里可以找到一些完整的代码示例,
谢谢,雷。

这是一个简单的代码,用于在W2K3上的JNDI中进行身份验证并进行LDAP搜索:
class TestAD{
static DirContext ldapContext;
public static void main (String[] args) throws NamingException
{
try
{
System.out.println("Début du test Active Directory");
Hashtable<String, String> ldapEnv = new Hashtable<String, String>(11);
ldapEnv.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
//ldapEnv.put(Context.PROVIDER_URL, "ldap://societe.fr:389");
ldapEnv.put(Context.PROVIDER_URL, "ldap://dom.fr:389");
ldapEnv.put(Context.SECURITY_AUTHENTICATION, "simple");
//ldapEnv.put(Context.SECURITY_PRINCIPAL, "cn=administrateur,cn=users,dc=societe,dc=fr");
ldapEnv.put(Context.SECURITY_PRINCIPAL, "cn=jean paul blanc,ou=MonOu,dc=dom,dc=fr");
ldapEnv.put(Context.SECURITY_CREDENTIALS, "pwd");
//ldapEnv.put(Context.SECURITY_PROTOCOL, "ssl");
//ldapEnv.put(Context.SECURITY_PROTOCOL, "simple");
ldapContext = new InitialDirContext(ldapEnv);
// Create the search controls
SearchControls searchCtls = new SearchControls();
//Specify the attributes to return
String returnedAtts[]={"sn","givenName", "samAccountName"};
searchCtls.setReturningAttributes(returnedAtts);
//Specify the search scope
searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);
//specify the LDAP search filter
String searchFilter = "(&(objectClass=user))";
//Specify the Base for the search
String searchBase = "dc=dom,dc=fr";
//initialize counter to total the results
int totalResults = 0;
// Search for objects using the filter
NamingEnumeration<SearchResult> answer = ldapContext.search(searchBase, searchFilter, searchCtls);
//Loop through the search results
while (answer.hasMoreElements())
{
SearchResult sr = (SearchResult)answer.next();
totalResults++;
System.out.println(">>>" + sr.getName());
Attributes attrs = sr.getAttributes();
System.out.println(">>>>>>" + attrs.get("samAccountName"));
}
System.out.println("Total results: " + totalResults);
ldapContext.close();
}
catch (Exception e)
{
System.out.println(" Search error: " + e);
e.printStackTrace();
System.exit(-1);
}
}
}
