Password validation script checking against stored passwords

I am able to create a script to check and validate for the password complexities outlined by our Active Directory GPO, but is there a way to check the password against the 1-24 stored passwords to validate that it hasn't been used before?
Thanks

Sorry Bill, I have written a forms based application in VB.NET that will allow the end-user to type in a proposed password. upon the press of the "Test" button the application loops through the characters in the textbox.text and determines if it
meets at least three of the following requirements:
1) the proposed password has at least one uppercase character
2) the proposed password has at least one lowercase character
3) the proposed password has at least one numeric value
4) the proposed password has at least one symbol
5) the proposed password has at least one Unicode character (non upper/lower case)
and an over all check that it meets the length requirements
I am hoping to find a way to check against the stored passwords to find out if the password has been used before.
Thanks,
-Ken

Fire fox will not save any passwords even after checking the save passwords box

I don't know how else to say it, the save password does not work even after checking the save password box if I can't get it fixed I'll use some one else

Go to Tools | Options and choose the Security tab from the Options dialog. Check the "Remember passwords for sites" checkbox. Click the Exceptions button to make sure the site you want to remember is not listed.
From that point on, Firefox will record the username and password combination you enter for a site provided it can recognized those fields in the website form. If the username and password are not already recorded for that site, a bar will expand down at the top of the webpage below the page tabs asking you if you want to remember or ignore that new information. Clicking the Remember button will record that information for that site. When you visit that same form again, either the single recorded username and password should automatically appear in the form fields, or a drop-down list of choices will appear when you set the focus to that field. The choices can be filtered by typing the first letters.
If the "Save password" checkbox you mentioned is displayed on the webpage, it is not a part of Firefox and is a function of the webpage of that site, so it does not affect the ability of Firefox to remember usernames and passwords for a particular site.

Mail not using stored password after failure to connect

I am using Mail to access several mail accounts on OSX Lion.
If Mail fails to connect to one of these accounts, when it next tries to connect, it prompts for a password instead of using the stored password.
This is proving a problem as I have one account which I frequently have problems connecting to. Therefore I get frequent annoying pop-ups asking for the password when Mail automatically checks for new mail.
Is there any way to change this behaviour?

I agree this can be annoying. But sometimes it's difficult to fix because it could be on the Server end vs a Keychain issue. You could go to Keychain and do a few things.
1) First, in Keychain, make sure your Keychain password is correct.
2) Close Mail. Delete the Keychain item associated with your mail password for the account you're having trouble with.
3) Open Mail, you'll be prompted for your passwork: select to save in Keychain
Keychain is Located in .../Applications/Utilities/Keychain Access. Below is an example of the Keychain

How can I see stored passwords in Mavericks?

I recently installed Mavericks but am having a problem seeing any of my passwords saved in Safari. Previously, I simply clicked on Safari, Preferences, Passwords and then checked the "Show Passwords for Selected Websites" box for the site I wanted to see the Password for. Since upgrading to Mavericks, it won't allow me to check the Show Passwords box and it won't allow me to see any of my previously saved passwords for any sites. This is not good news as I have a dreadful memory and can't remember passwords at all and have always relied on my Mac to do it for me. Has anyone else found the same thing and any suggestions as to how I can fix this?

Then, revert back to your MLion installation and see if the issue persists. Otherwise, I'm out of ideas, except to suggest that you contact Apple's Support, formerly Apple Express Lane.

Check if username/password is valid in database

In this old thread:
HTMLDB Connection Pooling with Oracle usernames
sspadafo mentions that it is possible (at least for apex when processing a database account authentication) to check if a given username/password is valid in the current database. Look for " the login API will call a new function in the database to check a username/pw combination." in the above thread.
Question: is this "function in the database" available to developers? if so, how to use it?

Hello,
and thanks for your answer. I'm aware of that old trick with 'alter user identified by values' but wish to avoid that, exactly for its drawbacks. I'm not creating a custom authentication solution, DB account is fine for me.
I wish to provide users the ability to change their (database) password in the apex application (which of course uses database account authentication). Changing the password is trivial; but usually in a 'change ypur password' form the users are prompted for their current password too (it is for security reasons). So:
1.user enters their current password and desired new password (twice)
2.app checks if current password is valid <-here I hope to use the beforementioned DB function
3.app issues the 'alter user identified by' statement

Powershell script monitor with encrypted password

I have created a powershell script based monitor in my management pack and everything is ok but I can't get my credentials work inside the script. I want to open pssession to another computer with my credentials. I have triple checked that my pssession is
working because I can access it from powershell console.
This works perfectly at local server from PSconsole:
$EncryptedPassword ="01000000d08c9ddf0115d1118c7a00c04fc297eb01000000534b2....etc...etc..."
$pw = convertto-securestring -String $EncryptedPassword
$cred = new-object System.Management.Automation.PSCredential -argumentlist "MyDOMAIN\MyACCOUNT",$pw
$s = New-PSSession -ComputerName "MyServer" -Port MyPort -Credential $cred
But when I run the same lines inside my management pack the convertto-securestring
does nothing, it just wont convert the encrypted password to secure string!
I have tried this plain text method and it works
inside my management pack, but I don't want to use it because you can see the password in plain text:
ConvertTo-SecureString -String "myPlainTextPassword" -AsPlainText -Force
This is the $error variable, so it's basically says that I don't have anything in the password secure string variable because the convertion did not work for some reason:
The argument is null. Provide a valid value for the argument, and then try running the command again. Cannot process argument transformation on parameter 'Credential'. PromptForCredential Exception calling ".ctor" with "2" argument(s):
"Cannot process argument because the value of argument "password" is null. Change the value of argument "password" to a non-null value." The system cannot find the file specified. Exception calling "SecureStringToBSTR"
with "1" argument(s): "Value cannot be null. Parameter name: s" The system cannot find the file specified. Exception calling "SecureStringToBSTR" with "1" argument(s): "Value cannot be null. Parameter name: s"
The system cannot find the file specified.
So is there some known issue with SCOM Agent / management pack when you are dealing with convertto-securestring
function with encrypted passwords?
I used these methods to encrypt the password: Technet article about encryption

I got it to work!

Ability to check password history without trying to set password?

Is there a way to check a given password against a user's current password & password history without trying to set their password?
The user's policy has the "passwordInHistory" and some other password policies enabled.
If possible, could this be done via a non root (cn=directory manager) account granted the correct permissions?
Edited by: raymondrewalker on Feb 2, 2010 10:02 AM

The attribute with past password is pwdHistory. The current password is in userPassword. You can do a ldapsearch to fetch them.
And you can use the pwdhash command to check if the hashed value match a specific password. The command should look like this:
/opt/SUNWdsee/ds6/bin/pwdhash -D ... -c {SSHA}encryptedpassword== testpassword
With a little script it's possible to do this in an automatic way. I don't know if anyone can run the pwdhash command and how to give permission to the userPassword and pwdHistory attributes.

DB password on scripted JDBC adapter

I am evaluating IDM 7.0 and tried to make a scripted JDBC Resource adapter
based on the simple table example. I succeeded in testing the DB connection
(Oracle 10.1 on Linux), but when I try to add the resource to an account, I get
[codeThere was an error while attempting to check the dictionary for the new password. Failure : com.waveset.util.WavesetException: XPRESS <invoke> exception
==> com.waveset.util.WavesetException: Can't call method queryString on class com.waveset.util.JdbcUtil
==> com.waveset.util.WavesetException: 
==> java.sql.SQLException: ORA-01017: invalid username/password; logon denied
]
which implies that the db user name (or password) is not right. But it should
be, since the connection test succeeded ?!

Yes, you are right, there was problems with dictionary password. I had
set the password dictionary , since it was dropped for some reason.
Now the resource works; well actually not. I get error
Account 'base' not found in Resource 'Oracle JDBC'.
But, I am trying to add the resource to existing account. The Linux resource
creates the account if it does not exist, so how can I do this on scripted JDBC?
BTW where is the password dictionary documented? I had to trace
Oracle to see what name the table is and then guess the attribute name
and type. I found a file dictionary.txt which describes the DDL, but not for
what it is (i.e. password list is not mentioned).

I have no folder for firefox in application support... where can I find the stored passwords from my time machine back up!!?

Everywhere I look it says I should have a folder for Firefox in library/applicationsupport/ BUT I don't have one! I'm looking to restore passwords from a time machine back up but there's no Firefox folder so I don't where to look. I even did a fresh install of Firefox on my mac and even then it never created a Firefox folder in library/applicationsupport/... they must be store somewhere in my back up...!?

Hello kamilr, check also in :
~/Library/Mozilla/Firefox/Profiles/<profile folder>
The tilde character (~) refers to the current user's Home folder, so ~/Library is the /Macintosh HD/Users/<username>/Library folder.
note that in mac 10.7 and above, the ~/Library folder is hidden by default, see : http://kb.mozillazine.org/Show_hidden_files_and_folders#Mac_OS_X
when you find the file seek for '''key3.db''' and '''signons.sqlite''' files.
Your passwords are stored in two different files, both of which are required:
'''key3.db''' - This file stores your key database for your passwords. To transfer your saved passwords, you must copy this file along with the following file.
'''signons.sqlite''' - Saved passwords
thank you

J_security_check in form-based authentication - not checking for blank passwords

I am using the LDAP Security Realm to authenticate against an iPlanet
Directory Server. All works as expected when a user-id and password
are entered for form-based authentication.
However, when a userid is entered but no password, j_security_check
logs the user in successfully. Aparently, this is correct LDAP
behaviour as anonymous login to the LDAP server is permitted. It seems
that the j_security_check servlet should check for blank passwords
before trying to authenticate against the LDAP server and fail
authentication if this is the case.
Has anyone else experienced this problem?

Hi Brian,
I do not believe it is j_security_check's job to check for blank
passwords.
In many security realms, it is "legal" for a user to have a blank
password. j_security_check forwards whatever password was entered so that
even users with blank passwords can be authenticated by the realm on the
backend. For this reason I believe that j_security_check is "doing the
right thing" by just forwarding whatever is presented to it, rather than
having its own logic. It is best if j_security_check just acts as a very
dumb middle man.
If behavior was altered, it is true that your particular problem would be
solved, but then many other people would have a problem with their users
with blank passwords authenticating properly...
Try looking into how to disable anonymous logins on the LDAP end of
things. Hope this helps.
Cheers,
Joe Jerry

Bringing back an old password validation rule

Good afternoon
On our old 4.6C system, there was a password validation rule that stated the first three characters of the password cannot occur in the same order in the user ID. This rule was removed when we upgraded to ECC 6.0
While the users hated that rule, that rule was a SOX requirement at our company and I would like to have it back. Before I resort to programming user exits, is there a way to reactivate or at least simulate that rule? I cannot use USR40 because not only does it effect all users on the system, it only works on the second logon and not at validation time.
If programming user exits like EXIT_SAPLSUSF_001 is my only option, where can I get the password at logon time? From my understanding, SAP does not store this in a system value or even a global variable or table to prevent the recording of passwords. While this is a valid security reason, it would solve the resurrection of this password role through programming.
Please advise.
Kind Regards
Moggie

Hi Moggie,
> Pending the result of the contract programmer's research, placing a 3 character prefix of each new user ID in table USR40 is looking like the best option, though I do hate to place that kind of check for all user IDS when only one ID really needs that validation rule.
A problem with that will soon arise when you have for example 10000 user ID's and want the users to have the opportunity to use strong pass-phrases (not just pass-words). Additionally, the passwords are now case-sensitive but the user ID is not. A pass-phrase for users such as "The_D0g_&_Cat_r_FAT" would go undetected even if you have any "THERON's" in the system, but why should it not be allowed? It's a good one!
Users will soon notice that only passwords which are very cryptic can be used, and they will start writing them down on Post-It's.
While that is going on... the "real sinners" who dish out weak or the same initial / reset passwords (like "INIT1234") or administrate the users for whom passwords don't change (like "RFC4PROD") will not have any further "idiot-proof" controls as it is only a warning, which is intentional.
> If the passwords are cycled regularly, adhere to profile values in the instance that encourage strict password rules, and are kept private and secure, it is not a compliance issue to the auditors.
There you have it.
Tell them that. Even if they do use the first 3 bname characters as the first 3 CAPS_ON password characters, they won't be able to do it for long anyway if the password rules are appropriate...
Incase you are not aware of it, please also take a look at (and search here and SAP notes for) infos about instance parameter login/password_compliance_to_current_policy (e.g. SAP Note 862989). With appropriate minimum password rules (not overkilled - because the system must still be able to generate compliant wizard-passwords!), you will catch the bigger risks than any one 'BSM?????'s in there somewhere....
Cheers,

Extend WL Authentication Provider Password Validation

Hi folks
I'm looking for any advice on how to extend the OOB password validation that is available and documented here:
http://docs.oracle.com/cd/E12840_01/wls/docs103/secmanage/atn.html#wp1212100
Specifically we'd like to test whether the desired password has been used in the last 8 they've used and also to enforce that it expire after x days. Any pointers would be much appreciated.
Thanks,
Paul

1- How can an authentication provider supports password validation providers ?
We decided to make our own authentication provider so I doubt we support it
Yes, your custom authentication provider will not support it.
2- How it is suppose to work ?
Now, when a user change his password (or any of his attributes), we call a stored procedure (DB) which updates the user table ...
The way I see it, the web application should call the password validation provider before (or instead and then the provider will call the stored procedure)
Have u configured the a databse authenticator? Looks like you are modifying the password in the database directly ( using stored procedures) so Password Validator will not come in picture at all.

Storing password in property file

i have an application which needs to read some values from property file but one problem is
i need to store the password there as well. storing password as a plaintext is not acceptable for this case. is there any suggestion how to do it? and ofcourse this property file needs must be easy to modify.

Instead of storing the password as plaintext you can
just store its digest with an algorithm like MD5 or
SHA. In order to check the user password your
application just have to compute the hash of the user
password and compare it with the stored digest.
In this case, be VERY carrefully with your
implementation: there's a lot of tricks that can
collapse all your application security features.Storing a digest is appropriate if you are trying to implement an authentication mechanism, but I expect the original poster is storing passwords in a properties file so his program can read them in and use them when connecting to external resources.
For such purpose, storing a digest would not be useful. It is this scenario that is discussed in the thread I directed him too.
Regards.

I loaded what I guess is the new version of Firefox and it completely changed my whole task bar. I don't have my Norton Logins with stored passwords, and it's hard to find my favorites. Help get it back to how it was.

To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data. See https://support.mozilla.com/kb/Uninstalling+Firefox
You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.
To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.
For details of how to find your profile folder see https://support.mozilla.com/kb/Profiles

How to access the stored password list of N9 native browser?

most everything should be listed here.
there was a way to see the website data and stored information, but not the passwords. they were ************
you were only able to delete the login information, and unfortunately, since i have not used the device in so long, have forgotten the language.
so you will have to dig a bit.
it was a command that you would enter into the browser address bar.
if it comes to me i will repost, but for now...check here.
