如何使用Java操作LDAP之LDAP连接

public static void main(String[] args) {

String url = "ldap://10.0.0.10:389/";

String domain = "dc=dtas,dc=com";

String user = "cn=administrator,cn=users";

String password = "111111";

HashtableString, String env = new HashtableString, String();

env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory"); // LDAP 工厂

env.put(Context.SECURITY_AUTHENTICATION, "simple"); // LDAP访问安全级别

env.put(Context.PROVIDER_URL, url);

env.put(Context.SECURITY_PRINCIPAL, user+","+domain); // 填DN

env.put(Context.SECURITY_CREDENTIALS, password); // AD Password

env.put("java.naming.ldap.attributes.binary", "objectSid objectGUID");

LdapContext ldapCtx = null;

try {

ldapCtx = new InitialLdapContext(env , null);

queryGroup(ldapCtx);

//queryUser(ldapCtx);

} catch (NamingException e) {

e.printStackTrace();

} finally {

if(ldapCtx != null) {

try {

ldapCtx.close();

} catch (NamingException e) {

}

}

}

}

private static void queryGroup(LdapContext ldapCtx) throws NamingException {

SearchControls searchCtls = new SearchControls();

searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE);

String searchFilter = "objectClass=organizationalUnit";

String searchBase = "ou=myDeptSubDept,ou=myDept,dc=DS-66,dc=com";

String returnedAtts[] = {"distinguishedName", "objectGUID", "name"};

searchCtls.setReturningAttributes(returnedAtts);

NamingEnumerationSearchResult answer = ldapCtx.search(searchBase, searchFilter, searchCtls);

while (answer.hasMoreElements()) {

SearchResult sr = answer.next();

Attributes Attrs = sr.getAttributes();

if (Attrs != null) {

NamingEnumeration? ne = Attrs.getAll();

while(ne.hasMore()) {

Attribute Attr = (Attribute)ne.next();

String name = Attr.getID();

Enumeration? values = Attr.getAll();

if (values != null) { // 迭代

while (values.hasMoreElements()) {

String value = "";

if("objectGUID".equals(name)) {

value = UUID.nameUUIDFromBytes((byte[]) values.nextElement()).toString();

} else {

value = (String)values.nextElement();

}

System.out.println(name + " " + value);

}

}

}

System.out.println("=====================");

}

}

}

Java获取Ldap叶子节点

使用netscape的ldap工具包。使用其它的工具包，写法类似。

注：必须知道base dn，以下假定ou=admin为base dn。若有明确的base dn，那写法比如：ou=admin,o=test1

源代码如下：

==========================

import netscape.ldap.*;

public class SearchTest {

public static void main(String[] args) {

LDAPConnection lc = null;

LDAPEntry findEntry = null;

int status = -1;

try {

// lc = ConnectionPool.

lc = new LDAPConnection();

/* Connect to server */

String MY_HOST = "localhost";

int MY_PORT = 389;

lc.connect(MY_HOST, MY_PORT);

System.out.println("1=========" +lc.isConnected());

lc.authenticate("cn=Directory Manager","password");

System.out.println("2=========" +lc.isConnected());

/* search for all entries with surname of Jensen */

String MY_FILTER = "(objectclass=*)";

String MY_SEARCHBASE = "ou=admin";

LDAPSearchConstraints cons = lc.getSearchConstraints();

cons.setBatchSize(0);

cons.setMaxResults(5);

MY_FILTER = "(objectclass=*)" ;

LDAPSearchResults res = lc.search(MY_SEARCHBASE,

LDAPConnection.SCOPE_ONE,

MY_FILTER,

null,

false,

cons);

while (res.hasMoreElements()) {

LDAPEntry cLDAPEntry = res.next() ;

System.out.println("" + cLDAPEntry.getDN());

System.out.println("" + cLDAPEntry.toString());

}

status = 0;

} catch (LDAPException e) {

System.out.println("Error: " + e.toString());

e.printStackTrace();

}

/* Done, so disconnect */

if ((lc != null) lc.isConnected()) {

try {

lc.disconnect();

System.out.println("3=========" +lc.isConnected());

} catch (LDAPException e) {

System.out.println("Error: " + e.toString());

}

}

System.out.println("4=========" +lc.isConnected());

System.exit(status);

}

}

用JAVA取LDAP数据库中的信息

Context.SECURITY_PRINCIPAL这个相当于账号。不给你你怎么登陆ldap服务器。估计你能给出客户给了哪些信息吗。不需要你全部给出。
