具有JNDI.LDAP的LDAP属性

Question

我正在使用LDAP模块登录我的Web应用程序。 我可以使用以下代码成功检查登录名。

env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "LDAP://my-company.com:389/ou=people,ou=intranet,dc=company,dc=com");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "uid="+ user +",dc=company,dc=com");
env.put(Context.SECURITY_CREDENTIALS, pwd);

try {
// Create initial context
DirContext ctx = new InitialDirContext(env);
// Close the context when we're done
b = true;
ctx.close();
}

但是我试图从连接中获取属性，例如，名字，通用名，邮件ID等

在您的try块中尝试

SearchControls constraints = new SearchControls();
constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);

String[] attrIDs = { "CommonNames","firstname","givenName","uid","email"};
constraints.setReturningAttributes(attrIDs);

NamingEnumeration answer = ctx.search("", "uid="+user, constraints);
if (answer.hasMore()) {

Attributes attrs = ((SearchResult) answer.next()).getAttributes();
CommonNames= (attrs.get("CommonNames").toString());
System.out.println(CommonNames);


}
