java连接ldap服务器_从Java应用程序连接LDAP服务器「建议收藏」

我正在构建一个基于GXT(J2EE)的应用程序.现在的问题是我必须将应用程序连接到LDAP服务器.您能告诉我如何从我们的Java应用程序连接LDAP服务器以及我将使用哪些库或API？

解决方法:

要连接到LDAP,请查看以下包/类：

javax.naming.directory.*

javax.naming.ladp.*

com.sun.jndi.ldap.LdapCtxFactory

com.sun.jndi.ldap.ControlFactory

示例代码：

//build a hashtable containing all the necessary configuration parameters

Hashtable environment = new Hashtable();

environment.put(LdapContext.CONTROL_FACTORIES, conf.getProperty(“ldap.factories.control”));

environment.put(Context.INITIAL_CONTEXT_FACTORY, conf.getProperty(“ldap.factories.initctx”));

environment.put(Context.PROVIDER_URL, conf.getProperty(“ldap.host”));

environment.put(Context.SECURITY_AUTHENTICATION, “simple”);

environment.put(Context.SECURITY_PRINCIPAL, conf.getProperty(“ldap.user”));

environment.put(Context.SECURITY_CREDENTIALS, conf.getProperty(“ldap.password”));

environment.put(Context.STATE_FACTORIES, “PersonStateFactory”);

environment.put(Context.OBJECT_FACTORIES, “PersonObjectFactory”);

// connect to LDAP

DirContext ctx = new InitialDirContext(environment);

// Specify the search filter

String FILTER = “(&(objectClass=Person) ((sAMAccountName=” + user.getUsername() + “)))”;

// limit returned attributes to those we care about

String[] attrIDs = { “sn”, “givenName” };

SearchControls ctls = new SearchControls();

ctls.setReturningAttributes(attrIDs);

ctls.setSearchScope(SearchControls.SUBTREE_SCOPE);

// Search for objects using filter and controls

NamingEnumeration answer = ctx.search(searchBase, FILTER, ctls);

…

SearchResult sr = (SearchResult) answer.next();

Attributes attrs = sr.getAttributes();

surName = attrs.get(“sn”).toString();

givenName = attrs.get(“givenName”).toString();

…

在这个例子中,我有一个Configuration对象,它从配置文件中读取这些值.

价值观将是：

# LDAP parameters

ldap.host = ldap://ldap.mydomain.com:389

ldap.factories.initctx = com.sun.jndi.ldap.LdapCtxFactory

ldap.factories.control = com.sun.jndi.ldap.ControlFactory

ldap.searchbase = dc=mydomain,dc=us

ldap.user = MYDOMAIN.COM\\ldap-user

ldap.userBase= MYDOMAIN.COM\\

ldap.password = ******
