问题描述
我正在使用 LDAP 和 Java 搜索.这是我的 LDIF 导出的简单组织
I am playing with LDAP and Java search. Here's my LDIF export with a simple organization
version: 1 dn: dc=example,dc=com objectClass: organization objectClass: dcObject objectClass: top dc: example o: MyOrganization description: Test Description dn: ou=people, dc=example,dc=com objectClass: organizationalUnit objectClass: top ou: people description: All users in demo company dn: cn=Johnny Doe,ou=people,dc=example,dc=com objectClass: organizationalPerson objectClass: person objectClass: inetOrgPerson objectClass: top cn: Johnny Doe sn: Johnny homephone: 123-456-7890 mail: johnny@johnny.com ou: Development uid: jjohnny userpassword:: johnny dn: cn=Samuel Johnson,ou=people,dc=example,dc=com objectClass: organizationalPerson objectClass: person objectClass: inetOrgPerson objectClass: top cn: Samuel Johnson sn: Samuel homephone: 123-456-7890 mail: sam@ssam.com ou: Accounts uid: ssam userpassword:: sammy
如何运行 Java 片段以从 LDAP 服务器获取所有用户?我的 Apache DS 目录服务器上没有身份验证设置.
How do I run a Java snippet to get all users from the LDAP server? There's no authentication set-up on my Apache DS Directory Server.
Hashtable env = new Hashtable(11);
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://localhost:10389/dc=example,dc=com");
env.put(Context.SECURITY_AUTHENTICATION, "none");
try {
// Create initial context
DirContext ctx = new InitialDirContext(env);
Object obj = new Object();
// want to print all users from the LDAP server
System.out.println(obj.toString());
ctx.close();
}
推荐答案
try {
LdapContext ctx = new InitialLdapContext(env, null);
ctx.setRequestControls(null);
NamingEnumeration<?> namingEnum = ctx.search("ou=people,dc=example,dc=com", "(objectclass=user)", getSimpleSearchControls());
while (namingEnum.hasMore ()) {
SearchResult result = (SearchResult) namingEnum.next ();
Attributes attrs = result.getAttributes ();
System.out.println(attrs.get("cn"));
}
namingEnum.close();
} catch (Exception e) {
e.printStackTrace();
}
private SearchControls getSimpleSearchControls() {
SearchControls searchControls = new SearchControls();
searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);
searchControls.setTimeLimit(30000);
//String[] attrIDs = {"objectGUID"};
//searchControls.setReturningAttributes(attrIDs);
return searchControls;
}
