Hi Experts

I have manage to change the password but I have a few issues
1. When I change the password its still holds the old pass and new password
2. When I try and change a user password that's not direct under the base but under a folder (CN=Users) it does not allow me. What troubles me is that by scope is set to SUBTREE_SCOPE.

I will await any replies.

My New Code is posted below

>>When I change the password its still holds the old pass and new password
Where does it hold it? You mean that you end up with two different attributes with the same name?

>>2. When I try and change a user password that's not direct under the base but under a folder (CN=Users) it does not allow me. What troubles me is that by scope is set to SUBTREE_SCOPE.
What is the error in this case? I suspect permission issues - that's why I ask.

Hi

>>When I change the password its still holds the old pass and new password
    Meaning I can use the old password and the new password. Hope this make sense

>>2. When I try and change a user password that's not direct under the base but under a folder
     I have created a user called javaldaptest3 under the base with member of only (Domain Users) Then I          created a user called (ABooysen2)  under a folder called Users with member of only (Domain Admins & Domain Users). I can use the javaldaptest3 account to authenticate but not the ABooysen2.

Hope this help

Many Thanks

Yeah - sounds like keeping both properties which soudsn familar but I need to try to remember where I had seen this happening.

Can you login with ABooysen2 from an ldap browser? Or change password using some other type of connection (let's eliminate the Java and see if the LDAP is not blocking you). Do you see an error message?

Hi

There was something wrong with ABooysen2 i created a javaldaptest6 under cn=Users with the same memeber list as ABooysen2 and it works 100%. So that means that somehow ABooysen2 was corrupted.

So now it's just the this issue that I need assistance/help with

OK, this is the user changes his own password?  

try this (keep in mind that this user now have both old passwords so you might need to clean a bit around it (or use another user):

ModificationItem mods[] = new ModificationItem[2];
mods[0] = new ModificationItem(DirContext.REMOVE_ATTRIBUTE, new BasicAttribute("unicodePwd", oldUnicodePassword));            
mods[1] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, new  BasicAttribute("unicodePwd", newUnicodePassword));

it's permission related - the Admin can reset a password but the user need to remove and add. Let me know if this did work and if not -- do you see any exceptions.

Hi

When I put
ModificationItem mods[] = new ModificationItem[2];
mods[0] = new ModificationItem(DirContext.REMOVE_ATTRIBUTE, new BasicAttribute("unicodePwd", oldUnicodePassword));            
mods[1] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE, new  BasicAttribute("unicodePwd", newUnicodePassword));


I am getting a Error

javax.naming.directory.NoSuchAttributeException: [LDAP: error code 16 - 00002085: AtrErr: DSID-0319067C, #1:
      0: 00002085: DSID-0319067C, problem 1001 (NO_ATTRIBUTE_OR_VAL), data 0, Att 9005a (unicodePwd):len 30

Is this with the user that have 2 passwords now?

OK.. that's because you login with one user and try to change the password of another. Which is a reset. So you do not remove/replace; just replace Do you know the password of the user you try to change the password  for? If you do -- use the method above. If you do not, it should not be saving it as a second password.

Need to run on a meetinng. Please see http://forums.sun.com/thread.jspa?threadID=592611 -- there are some explanations and examples there.
