Active Directory validate service account and user accounts
- by Padur
Hello folks
I have an issue here, I guess you all know what is AD service account and why it is used for, if not please see the below description ?
SSL-Explorer requires a dedicated Active Directory account to use for authenticating AD users. This account serves as a link to your Active Directory database. If the Service Account is not found on your AD database then the SSL-Explorer service will not start.
Well I have Active Directory service account details and user submitted login/password details.In the code below I validated service account by giving MEMBER_GRPUP and adminPassword and I check whether the user exists in Active Directory by submitting samaaccountname but my question here is how do I validate the password submitted for that user? I am not sure how to do this, I appreciate if anybody has any suggestions on this. Thanks for your time.
public boolean validateUserFromActiveDirectory(String userId) {
final String MEMBER_GROUP = "CN=asdadasd,OU=asdasdasd Accounts,OU=adasdas,OU=asdasdas,DC=asdasdas,DC=asdasdas,DC=adasdasd,DC=asdasdasd";
String employeeNumber = "";
final String LDAP_INIT_CTX = "com.sun.jndi.ldap.LdapCtxFactory";
final String LDAP_URL = "ldap://xx-ssssssss.eee.eee.eeeee.eeeee:636";
final String MY_ATTRS[] = { "employeeNumber" };
String adminPassword = "somepassword";
String securityProtocol = "ssl";
boolean isValidUser = false;
try {
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, LDAP_INIT_CTX);
env.put(Context.PROVIDER_URL, LDAP_URL);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.REFERRAL, "follow");
env.put(Context.SECURITY_PRINCIPAL, MEMBER_GROUP);
env.put(Context.SECURITY_CREDENTIALS, adminPassword);
env.put(Context.SECURITY_PROTOCOL, securityProtocol);
//C:\Documents and Settings\yourusername\Local Settings\Temp
File tf = File.createTempFile("adentTruststore", ".jks");
tf.deleteOnExit();
byte buffer[] = new byte[0x1000];
ClassLoader cl = JNDI.class.getClassLoader();
InputStream in = cl.getResourceAsStream(
"someTruststore.jks");
FileOutputStream out = new FileOutputStream(tf);
int cnt;
while ((cnt = in.read(buffer)) != -1)
out.write(buffer, 0, cnt);
in.close();
out.close();
System.setProperty("javax.net.ssl.trustStore", tf
.getAbsolutePath());
DirContext context = new InitialLdapContext(env, null);
SearchControls searchControls = new SearchControls();
searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);
NamingEnumeration results = context.search(
"XX=ent,XX=abc,XX=aaaaa,XX=aaaa", "(sAMAccountName="
+ userId + ")", searchControls);
if (results != null && results.hasMore()) {
//some logic
}
}
} catch (Exception e) {
e.printStackTrace();
}
return isValidUser;
}
