JNDI LDAP在同一InitialDirContext对象中创建2个连接

Question

I need to create 1 ldap connexion (I use a application account ) and from this connection i need to create other connexion (user connection) from check if the uid and password is ok.

Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, ldapServerUrl);
env.put(Context.SECURITY_AUTHENTICATION, "none");

SearchControls searchCtrls = new SearchControls();
searchCtrls.setReturningAttributes(new String[] {});
searchCtrls.setSearchScope(SearchControls.SUBTREE_SCOPE);

String filter = "(&(cn=" + identifier + "))";

DirContext ctx = null;
ctx = new InitialDirContext(env);
NamingEnumeration<SearchResult> answer = ctx.search(
   ldapBaseDN, filter, searchCtrls);

String fullDN = null;
if (answer.hasMore()) {
    fullDN = answer.next().getNameInNamespace();

    ctx.close();
    ctx = null;

    env.put(Context.SECURITY_AUTHENTICATION, "simple");
    env.put(Context.SECURITY_PRINCIPAL, fullDN);
    env.put(Context.SECURITY_CREDENTIALS, password);

    ctx = new InitialDirContext(env);
    // here I must create the user connection for check if the uid and password is good.

    return true;
}

Thank you.

After you find the user in the LDAP DIT you should then modify tne environment to contain the user's DN and password and then issue LdapContext.reconnect() using the same Context .

You don't need to create a separate 'physical' connection.
