【问题描述】:
您好,我正在尝试从 LDAP 和该组中的用户获取所有 posixGroup。下面的代码是我到目前为止所做的,它返回了所有组,但我不确定如何获取这些组的用户。请指导我这种方法好吗?还是我应该先获取用户,然后根据 GID 获取组名?
public static void main(String[] args) {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL,"ldap://192.168.*.*:389");
env.put(Context.URL_PKG_PREFIXES, "com.sun.jndi.url");
env.put(Context.REFERRAL, "ignore");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "cn=manager,dc=*,dc=*");
env.put(Context.SECURITY_CREDENTIALS, "****");
DirContext ctx;
try {
ctx = new InitialDirContext(env);
} catch (NamingException e) {
throw new RuntimeException(e);
}
NamingEnumeration results = null;
try {
SearchControls controls = new SearchControls();
controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
results = ctx.search("ou=path,dc=*,dc=*", "(objectClass=posixGroup)",controls);
// Go through each item in list
while (results.hasMore()) {
SearchResult nc = (SearchResult)results.next();
Attributes att= nc.getAttributes();
System.out.println("Group Name "+ att.get("cn").get(0));
System.out.println("GID "+ att.get("GidNumber").get(0));
}
} catch (NameNotFoundException e) {
System.out.println("Error : "+e);
} catch (NamingException e) {
throw new RuntimeException(e);
} finally {
if (results != null) {
try {
results.close();
} catch (Exception e) {
System.out.println("Error : "+e);
}
}
if (ctx != null) {
try {
ctx.close();
} catch (Exception e) {
System.out.println("Error : "+e);
}
}
}
}
