Determining password expiry using java + ADLDS

If authentication fails, I have to determine that password has expired.
I can not use 'pwdLastSet' attribute because password policy depends on domain server.
I have to check the attribute 'msDS-UserPasswordExpired' whether it is true or false.
But I am not able to do it since it is constructed attribute.
I have seen it is done in .NET using 'RefreshCache' method.
How it can be done in Java?
Please note this is a repetition of an earlier thread as it was not answered

You may alter your profile beforehand:
ALTER PROFILE XYZ LIMIT PASSWORD_REUSE_MAX UNLIMITED

Setting password expiry using the SDK

Without using the iDS console, meaning just by using the SDK, could I set the period for password expiry?
Since the userPassword is a multi-value attribute, how can I differentiate between which is the password for signing-onto the server and which are passwords for other applications?

If you mean to configure the password policy using the SDK, a Modify operation for the base object "cn=config" and replacing the value of "PasswordMaxAge" attribute will work.
If you intend to set a specific expiration time for a specific user, you should not do this and let the server set the expiration time based on the configured password ploicy.
For more information on the password policy configuration, you can refer to the Administration Guide.
Also, although userPassword is multivalued, the pasword policy as currently defined in the Directory server suppose that the userPassword attribute contains only 1 value. If the password contains more than 1 value, the result of the password policy is undefined.
And there is no way to differentiate between passwords.

LDAP password replace using java script

Hi all!
I wrote a perl script to generate random password. It works great.
I have an existing java class which currently changes user password to
match user id in LDAP database.
I am trying to call my perl script from within java and parse the output
of the perl script to string value.
What would be the best way to approach this problem. I am new to java. I
know shell and perl programming and simple command substitution (back
quotes) would do the trick there. I know there is no such thing in java.
Your help is greatly appreciated.
Thank You.

It's probably because your id used in the Javascript to find the h:inputSecret tag is wrong. JSF appends parent id's in front of the children id's (and separates them with a colon). Check your HTML source and see.
The id you should be using is something like: "createUserForm:passwd"
Hope this helps,

Determining RAM size using Java

Hi,
Apologies in advance if this seems to be an oft-repeated topic. I just wanted to confirm if I am missing something or not.
I am trying to find the total amount of RAM available to the OS and am using the java management API to do it (I am using JDK 1.6 update 7):
import java.lang.management.ManagementFactory;
import com.sun.management.OperatingSystemMXBean;
public class Mem{
     public static void main(String[] args){
          OperatingSystemMXBean osb = (com.sun.management.OperatingSystemMXBean)ManagementFactory.getOperatingSystemMXBean();
          System.out.println(osb.getTotalPhysicalMemorySize());
}This code seems to return the correct value of total RAM on Linux. On Windows, however, I get some random value. I believe it could be because of this bug: [http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=132bbb6b3cbd535627637e96a07c?bug_id=6628662|http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=132bbb6b3cbd535627637e96a07c?bug_id=6628662] So I doubt I can use this approach on Windows.
An alternate way would be to call OS specific commands from within Java, parse the results I receive and use them. I would like to keep that as the last resort. I want to avoid JNI too.
My question is, is there any other way to retrieve the information? Are there lightweight third-party tools which can be integrated into my java code?
Any input will be greatly appreciated.
Thank you!

I need this info for a "setup" program which allows the end-user to choose how much max heap memory they want to allocate for their application. I don't want to display values which are beyond what is physically available in the system.Ok. IMHO this is not a great use of your time. First of all, total RAM is not nearly as important as total RAM - memory manager - OS. Second of all, system memory is more than just RAM. Virtual memory allows you to have much more in memory than your RAM.
IMHO you should leave this to the user to performance tune their own machine.

Password expiry redux

After an exhaustive RTFM session reading the docs on SGD 4.4; Kerberos, etc. and bombing out with password expiry time and time again I was told, in this forum, that there is an "unpublished bug" in the jre that ships with SGD 4.4, breaking AD password expiry. No fix or patch was mentioned.
Before wasting more time, could anyone tell me if there are any other "known issues" with AD password expiry using SGD 4.31? (BTW, it isn't working either).
regards,
-damon

this is correct, there is a bug in Java 1.6 that ships with both 4.31 and 4.40. The fix is in 1.6.0 update 4. Please check http://java.sun.com in the next week or so for details on when the update will be released. Please open a case with Sun Support so that the instructions for upgrading the existing JVM can be provided.

Unable to raise password expiry warning exception in OID using JAVA API

Hi,
We are maintaing the user information for our application in OID(9.2). During logon, it is required that a warning is given to the user according to the value set in "Password Expiration Warning" parameter.
A pl/sql program (using DBMS_LDAP/DBMS_LDAP_UTL packages) written to test password expiry raises the PWD_EXPIRE_WARN exception as expected. However we are unable to simulate the same using the JAVA APIs.
We did try some thing like the following:
public class SampleExpire {
public static void main(String argv[])
throws NamingException {
// Create InitialDirContext
InitialDirContext ctx = ConnectionUtil.getDefaultDirCtx( "TCS-UUODC4",
"4032",
"cn=orcladmin",
"welc0me" );
System.out.println("Hello");
// Create User Objects
User myuser = null,
try {
// Create User using a subscriber DN and the User DN
myuser = new User ( ctx,
Util.IDTYPE_DN,
"uid=C100013, ou=People, o=UUSD",
Util.IDTYPE_DN,
"ou=People, o=UUSD",
false );
catch ( UtilException e ) {
* Exception encountered in User object constructor
System.out.println("User creation failed");
// Authenticate User
try {
myuser.authenticateUser(ctx,User.CREDTYPE_PASSWD,"Z100013");
catch ( UtilException e ) {
* Authenticate fails
System.out.println("Authentication failed");
} // End of SampleExpire.java
The authenticate user does not raise any exception.
Am I missing something ?

If they've implemented the password system correctly there probably isn't a way of getting the password at all.

***How to use Java to change user password in *mdw file?

Hi,
Is it possible to use java to change user's password in the MS Access workgroup file(*mdw)? I have been searching for this topic for a long time, but no discoveries yet. Anyone has any idea?
Sincerely,
nonameisname

There is probably a windows API call that does it.
Once you find it, you wrap it in C code and then use JNI to call it from Java.

How to dynamically configure JPA setting at runtime using java code?

Hi,
I am new to EJB 3.0 and JPA. I am trying to help my company to deploy the use of JPA in EJB3.0. Currently, i am trying out with OpenJPA in IBM Webshpere Application Server 7.0. We have four different WAS servers running for testing, system integration testing, user testing and production respectively, and in each region, the configurations for data source, JDBC username and password, schema, etc are different. So i think i would need to configure the JPA setting during runtime using Java code that determines which is the environment. And apparently i am stuck with the limited knowledge i have.
1) I understand that i could override the JDBC in the persistence xml by creating entity manager using entity manager factory. But is it possible that i do similar thing by using inejction of persistence context on entity manager to obtain a container managed entity manager?
2) Alternatively, it is possible to create multiple persistence unit in the XML and inject different PU to the entity manager, am i right? But how to inject dynamically since @PersistenceContext(unitName="xxx") only accepts constant declaration.
3) Is it possible that the JDBC username and password are read from properties file?
Thanks for your help in advance!

Hi
Thanks for the reply.
Are you saying that i have to configure the data source authentication to the backend DB2 using the JAAS-J2C? Correct me if i am mistaken. I guess i am unable to do so as the application server setup only contains one data source, and the server hosted a number of applications. Every applications has their own JDBC username and password supply to the data source (the ID supplied at the DB2 side will decide which resource can access) and thus, i have to supply the username and password at runtime. Talked to the server guy and seems that it is not feasible to have seperate datasource for each applications as considered to the volume of applications hosted inside the server.
Any suggestion?

Update database logon in reports using java

Please review the code below and let me know where did I go wrong! I am able to login to CMS and able to retrieve the list of reports. Now, I am trying to update the database credentials for a single report using java (My requirement is to update all 200 reports though!).
This is the 100th time I go this error message: Failed to open the connection.report.lib.ReportSDKServerException: Failed to open the connection.
I also wrote a sample java program which tries to connect to the sql server database with same login credentials - this works perfectly fine. But, if I use the same connection url, driver name and login credentials, this report fails to update for whatever reason. Please help me ASAP..Thanks!

another interface is receive the password and determine whether it is valid or not...
Two interfaces is on different computer.....
I have to link these interfaces together using java....
PLS HELP!!!!!!

It sounds like you should probabally use RMI.That is, remote method invocation...these guys are doing a more complicated version of what you want to do:
http://www.experts-exchange.com/Programming/Programming_Languages/Java/Q_20680356.html#8935218
Be sure to check out Sun's RMI tutorial:

Happy coding! Sounds like a fun little project...I want to do some RMI sometime when I get a chance...
