适合云计算存储的认证

听说云计算这个词，是在2007年末。刚开始，感觉挺牛的。
这里，根据这一年的工作，把我常用树型存储的SunOne、OpenLDAP、AD和Domino的认证过程，以java语言方式，分别总结如下：
OpenLDAP
public static void main(String[] args) throws Exception {
Hashtable m_env = new Hashtable(5, 0.75f);
m_env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
m_env.put("java.naming.ldap.version", "3");
m_env.put(Context.PROVIDER_URL, "ldap://192.168.0.60:389");
m_env.put(Context.SECURITY_AUTHENTICATION, "simple");
m_env.put(Context.SECURITY_PRINCIPAL, "cn=Manager,dc=chinautrust,dc=com");
m_env.put(Context.SECURITY_CREDENTIALS, "secure");
LdapContext ctx = null;
try {
// Open an LDAP association
ctx = new InitialLdapContext(m_env, null);
if (ctx == null) {
try {
throw new ConnectException(
"Cann't connetect to ldap server");
} catch (ConnectException e) {
e.printStackTrace();
}
}
} catch (LinkException e1) {
e1.printStackTrace();
}
String rootDn = "ou=person,ou=utrust,dc=chinautrust,dc=com";
String filter = "objectclass=utrustbaseperson";
ArrayList<Object> listDn = new ArrayList<Object>();
try {
SearchControls constraints = new SearchControls();
// Set up search mode
constraints.setCountLimit(50);
constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
// Search
NamingEnumeration enumSearch = ctx.search(rootDn, filter, constraints);
constraints = null;
if (enumSearch == null) {
System.out.println("Have no NamingEnumeration.");
}
if (!enumSearch.hasMoreElements()) {
System.out.println("Have no element.");
}
while (enumSearch != null && enumSearch.hasMoreElements()) {
Object obj = enumSearch.nextElement();
if (obj instanceof SearchResult) {
SearchResult si = (SearchResult) obj;
if (!si.getName().equals("")) {
if ("".equals(rootDn) || rootDn == null) {
listDn.add(si.getName());
} else {
listDn.add(si.getName() + "," + rootDn);
}
}
si = null;
}
obj = null;
}
enumSearch = null;
} catch (Exception e) {
try {
throw e;
} catch (Exception e1) {
e1.printStackTrace();
}
}
System.out.println(listDn);
}
SunOne
public static void main(String[] args) throws Exception {
Hashtable m_env = new Hashtable(5, 0.75f);
m_env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
m_env.put("java.naming.ldap.version", "3");
m_env.put(Context.PROVIDER_URL, "ldap://192.168.0.60:389");
m_env.put(Context.SECURITY_AUTHENTICATION, "simple");
m_env.put(Context.SECURITY_PRINCIPAL, "cn=Directory Manager");
m_env.put(Context.SECURITY_CREDENTIALS, "secure");
LdapContext ctx = null;
try {
// Open an LDAP association
ctx = new InitialLdapContext(m_env, null);
if (ctx == null) {
try {
throw new ConnectException(
"Cann't connetect to ldap server");
} catch (ConnectException e) {
e.printStackTrace();
}
}
} catch (LinkException e1) {
e1.printStackTrace();
}
String rootDn = "ou=person,ou=utrust,dc=chinautrust,dc=com";
String filter = "objectclass=utrustbaseperson";
ArrayList<Object> listDn = new ArrayList<Object>();
try {
SearchControls constraints = new SearchControls();
// Set up search mode
constraints.setCountLimit(50);
constraints.setSearchScope(SearchControls.SUBTREE_SCOPE);
// Search
NamingEnumeration enumSearch = ctx.search(rootDn, filter, constraints);
constraints = null;
if (enumSearch == null) {
System.out.println("Have no NamingEnumeration.");
}
if (!enumSearch.hasMoreElements()) {
System.out.println("Have no element.");
}
while (enumSearch != null && enumSearch.hasMoreElements()) {
Object obj = enumSearch.nextElement();
if (obj instanceof SearchResult) {
SearchResult si = (SearchResult) obj;
if (!si.getName().equals("")) {
if ("".equals(rootDn) || rootDn == null) {
listDn.add(si.getName());
} else {
listDn.add(si.getName() + "," + rootDn);
}
}
si = null;
}
obj = null;
}
enumSearch = null;
} catch (Exception e) {
try {

System.out.println(listDn);
}
AD

Domino
