Account lockout for failed attempts in acs 5.1.0.44.6

Hi All ,
I have ACS1121 running version 5.1.0.44.6 on my network environement , I need to enable account lock-out for internal user during failed attempt for more than 8 times , How to achieve this .
I could see account lock-out for administrator user account , not for internal user .

In general this feature is not supported and is part of the CS 5.3 release which is scheduled for FCS later this year
However, looking at the list of patches I can see that the 5.2.0.26.4 cumulative patch includes a fix for the following:
CSCth12406: ACS 5 does not have option to disable local account on failed attempts
I am not familiar specifically with these changes but looking at the CDETS it appears that after the installation of the patch the following options are available:
1.Selected 'System Administration' in ACS under left pane in primary server.
2.Selected 'Users -> Authentication Settings -> Advanced ' . Account Disablement section will be displayed.
3.Selected check box 'Failed attempt exceeds' and provide count of number of attempts after which account is disable
Since you are on a 5.1 release you would need to upgrade to 5.2 and then install the patch (or 5.2.0.26.5 which is in fact the latest patch)

Blocking clients with repeating failed attempts in ACS 5.4

Hi
I use my ACS to authenticate clients from both LNS ans wireless.
There are always users with wrong configuration that repeat the authentication process and fail thousands time and 'hammer' the ACS servers.
Is there a way to block repeated failed attempts?
Thanks!
Naor.

Hi, and thanks for the quick reply! Few questions:
That will prevent clients from re-authenticating for 15 minutes?
If so, how client will be able to roam on campus? that requires re-authentication...

Random Account Lockout (How to trace source?)

In Windows 2003 server native domain environment: XP Pro machines have no issues, but all ~10 PCs that have Win7 Pro (in different offices) have their domain accounts locked out randomly throughout the day. Workstations have no passwords listed in credentials
management.
Suspect it is something on the workstations that is sending incorrect logon and triggering the invalid password lockout limit on domain policy. Found MSFT tools to trace in XP, but nothing for Win7. Does anyone know how to use Procmon or similiar tool to
trace such source on the workstations? Thank you.
(Procmon.exe from systernals)

Hi,
The user account has been automatically locked because too many invalid logon attempts or password change attempts have been requested.
We can run the LockoutStatus.exe on domain controller to identify and investigate the account lockout issue.
Troubleshooting tools:
By using this tool, we can gather and displays information about the specified user account including the domain admin's account
from all the domain controllers in the domain. In addition, the tool displays the user's badPwdCount value on each domain controller. The domain controllers that have a badPwdCount value that reflects the bad password threshold setting for the domain are the
domain controllers that are involved in the lockout. These domain controllers always include the PDC emulator operations master.
You may download the tool from the link
Download Account Lockout Status (LockoutStatus.exe)
http://www.microsoft.com/downloads/details.aspx?familyid=D1A5ED1D-CD55-4829-A189-99515B0E90F7&displaylang=en
Once we confirm the problematic computer, we can perform further research to locate the root cause. Actually, there are many possible
causes for bad password, such as cached password, schedule task, mapped drives, services, etc. Please remove the previous password cache which may be used by some applications and therefore cause the account lockout problem.
Troubleshooting steps:
1. Click Start, click Run, type "control userpasswords2" (without the quotation marks), and then click OK.
2. Click the Advanced tab.
3. Click the "Manage Password" button.
4. Check to see if these domain account's passwords are cached. If so, remove them.
5. Check if the problem has been resolved now.
If there is any application or service is running as the problematic user account, please disable it and then check whether the problem
occurs.
For your convenience, I'd like to list the common troubleshooting steps and resolutions for account lockouts as the following:
Common Causes for Account Lockouts
To avoid false lockouts, please check each computer on which a lockout occurred for the following behaviors:
Programs:
Many programs cache credentials or keep active threads that retain the credentials after a user changes their password.
Service accounts:
Service account passwords are cached by the service control manager on member computers that use the account as well as domain controllers.
If you reset the password for a service account and you do not reset the password in the service control manager, account lockouts for the service account occur. This is because the computers that use this account typically retry logon authentication by using
the previous password. To determine whether this is occurring, look for a pattern in the Netlogon log files and in the event log files on member computers. You can then configure the service control manager to use the new password and avoid future account
lockouts.
Bad Password Threshold is set too low:
This is one of the most common misconfiguration issues. Many companies set the Bad Password Threshold registry value to a value lower
than the default value of 10. If you set this value too low, false lockouts occur when programs automatically retry passwords that are not valid. Microsoft recommends that you leave this value at its default value of 10. For more information, see "Choosing
Account Lockout Settings for Your Deployment" in this document.
User logging on to multiple computers:
A user may log onto multiple computers at one time. Programs that are running on those computers may access network resources with
the user credentials of that user who is currently logged on. If the user changes their password on one of the computers, programs that are running on the other computers may continue to use the original password. Because those programs authenticate when they
request access to network resources, the old password continues to be used and the users account becomes locked out. To ensure that this behavior does not occur, users should log off of all computers, change the password from a single location, and then log
off and back on.
Stored user names and passwords retain redundant credentials:
If any of the saved credentials are the same as the logon credential, you should delete those credentials. The credentials are redundant
because Windows tries the logon credentials when explicit credentials are not found. To delete logon credentials, use the Stored User Names and Passwords tool. For more information about Stored User Names and Passwords, see online help in Windows XP and the
Windows Server 2003 family.
Scheduled tasks:
Scheduled processes may be configured to using credentials that have expired.
Persistent drive mappings:
Persistent drives may have been established with credentials that subsequently expired. If the user types explicit credentials when
they try to connect to a share, the credential is not persistent unless it is explicitly saved by Stored User Names and Passwords. Every time that the user logs off the network, logs on to the network, or restarts the computer, the authentication attempt fails
when Windows attempts to restore the connection because there are no stored credentials. To avoid this behavior, configure net use so that is does not make persistent connections. To do this, at a command prompt, please type net use /persistent:no. Alternately,
to ensure current credentials are used for persistent drives, disconnect and reconnect the persistent drive.
Active Directory replication:
User properties must replicate between domain controllers to ensure that account lockout information is processed properly. You should
verify that proper Active Directory replication is occurring.
Disconnected Terminal Server sessions:
Disconnected Terminal Server sessions may be running a process that accesses network resources with outdated authentication information.
A disconnected session can have the same effect as a user with multiple interactive logons and cause account lockout by using the outdated credentials. The only difference between a disconnected session and a user who is logged onto multiple computers is that
the source of the lockout comes from a single computer that is running Terminal Services.
Service accounts:
By default, most computer services are configured to start in the security context of the Local System account. However, you can
manually configure a service to use a specific user account and password. If you configure a service to start with a specific user account and that accounts password is changed, the service logon property must be updated with the new password or that service
may lock out the account.
Internet Information Services:
By default, IIS uses a token-caching mechanism that locally caches user account authentication information. If lockouts are limited to users who try to gain access
to Exchange mailboxes through Outlook Web Access and IIS, you can resolve the lockout by resetting the IIS token cache. For more information, see "Mailbox Access via OWA Depends on IIS Token Cache" in the
Microsoft Knowledge Base.
MSN Messenger and Microsoft Outlook:
If a user changes their domain password through Microsoft Outlook and the computer is running MSN Messenger, the client may become locked out. To resolve this behavior,
see "MSN Messenger May Cause Domain Account Lockout After a Password Change" in the
Microsoft Knowledge Base.

DSEE user account lockout notification

I am a new administrator for an Oracle Directory Server Enterprise Edition 11g installation. Currently we have an account lockout policy in place to lock an account after 20 failed attempts. Is there a way within the DSEE application to set it up to notify me by email when an account gets locked? If there is not a way to configure the application to send notification, what would be the best way to accomplish this task?
Thank You.

Hello,
There is no notification email or similar notif mechanims. Such feature is available with Oracle Unified Directory though.
I would say the simplest way would be to parse access logs and search for errors like
[09/Jun/2009:16:15:03 +1000] conn=2946 op=0 msgId=1 - BIND dn="uid=testuser,ou=people,ou=unix,dc=..." method=128 version=3
[09/Jun/2009:16:15:03 +1000] conn=2946 op=0 msgId=1 - RESULT err=53 tag=97 nentries=0 etime=0, Account inactivated. Contact system administrator.
Note: This is a old dsee log sniplet, so exact message might vary slighly.

ISE Guest Account Lockout

Hi,
I would like to disable account lockout for ISE Guest accounts resulting from login failures. In the ISE, there is a setting for Maximum Number of Login Attempts (with values from 1-9) in:
        Administration>Guest Management>Settings>Guest>Portal Policy
Can someone tell me where or how account lockout can be turned off for Guest accounts in the local database of the ISE/WLC.
Many thanks.

ACS 5.3 and Windows AD account lockout

Currently on 5.3.0.40.2 when a invalid password is attempted via TACACS or RADIUS to the AD identity store is locks the account out on the first failed attempt. The AD policy is lockout after three attempts. Is there a way to fix this issue so the account is not locked out with only one failed attempt? I see options for local password policys in ACS but nothing for the identity store. For what its worth this happened also with ACS 4.X deployment before we moved to ACS 5.3.
Just wanted to see if this is the expected behavior or if I should open a TAC case to see what is causing this.
Thanks.

Hi;
Well, we got it working. Not sure of the exact fix, but allow me to ramble, perhaps it will help someone else.
We think that a combinationof factors caused the problem. First, we had clock drift, and that resulted in clock skew messages in the logs like these:
Sep 20 18:06:03 ecb-acs1 adclient[8322]: INFO base.adagent start: Problem connecting to domain controller (KDC refused skey: Clock skew too great), will try again later.
and
ecb-acs1 adclient[1163]: WARN base.bind.cache LDAP fetch CN=bubba,OU=staff,OU=edcenter,OU=edcenterarea,OU=episd,DC=episd,DC=org threw unexpected exception: SASL bind to ldap/[email protected] - GSSAPI Mechanism with Kerberos error ": Clock skew too great"
Somehow the ACS lost the ntp config, very disturbing, because I know that one of the first things I did was setup NTP. So I re-did the ntp config, confirmed the time was accurate. Still failed. Then, because I was annoyed by the log entries comning out in UTC, I did a clock timezone to set it to local. That made the logs come out in local time, but might have caused other problems (I saw another forum entry for that) so I set it back to UTC.
This begs the question - how to leave the timezone at UTC but fix the timestamps for the logs? This is easy on Cisco switches.
Various reboots of the ACS after deleting the object in AD did not fix the problem. During these reboots I continued to use the original userid and password to authenticate. At all times, the "test connection" button showed that the credentials were OK.
Because we had recently added our first Win2008 domain controller to our world (all ther other DCs are Win2k3), we started worrying about this:
http://support.microsoft.com/kb/978055/en-us
But, after some checking, it seems as if we already had the fix applied.
Next, we created a dedicated user in AD for the ACS to use when authenticating. Deleted the ACS object, restarted the ACS, applied those new credentials. Still broken.
Our AD admin looked in various logs and found some things, here is his summary:
----------- from Danny --------
Checked the domain controller log under system. Found the following:
While processing an AS request for target service krbtgt, the account ecb-acs1$ did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 1). The requested etypes : 17. The accounts available etypes : 23 -133 -128 3 1. Changing or resetting the password of ecb-acs1$ will generate a proper key.
and
While processing an AS request for target service krbtgt, the account stcrye did not have a suitable key for generating a Kerberos ticket (the missing key has an ID of 2). The requested etypes : 18. The accounts available etypes : 23 -133 -128 3 1. Changing or resetting the password of stcrye will generate a proper key.
This may be related to either clock scew between acs and the domain or introducing server 2008 domain controllers into an existing server 2003 domain.
On a desperate hunch, after yet again deleting the ACS object in AD and reloading the ACS, I used the new dedicated ACS user account, but gave it a wrong password. Hit save, watched it fail. Then I put in the correct password, hit save, and it worked! Finall we have re-joined and are connected to the domain.
BUT ... I have now lost all confidence in ACS 5.3 . We are in the middle of a major rollout of WiFi clients using 802.1x authentitcation, replacing our previous pre-shared WPA setup. We are talking > 20,000 WiFi clients. If ACS <--> AD is not rock-solid, I need to try something else. Should we consider using LDAPS instead?

ACS v5.1 - Can internal users be disabled after x failed attempts?

I have noticed under authentication settings for internal user accounts there is no setting to disable the account after x number of failed attempts (ACS v5.1). This is such a fundamental requirement for user accounts that I am wondering whether I have missed something. (They include this option on Administration accounts)
Does anyone know if can this be set somewhere else or is Cisco going to implement it in a later version?
Many Thanks

Hello jrabinow ,
Thanks a lot for the reply .
We already have our AD setup to lock account of users who failed 3 consecutive windows login attempts .
However when network administrators fail to login after 3 consecutive attempts into a network device, they can still login into a network device if they provide their correct AD credentials .
Is there any specific configuration that needs to be done on the AD to be aware of the failed login attempts on the network devices and count it the same as a failed windows login attempt ?!
Kind Regards ,
Moussa

"Disable account if failed attempts exceed x on" group object

When setting up a group in ACS 4.1, how do you include the "disable account if failed attempts exceed x" on the Group object. I see there have been some topics on this for older ACS versions (3.x) where it was not possible. Just wondering if anyone knows if this is possible on ACS 4.1 or possibly 4.2?

Hi,
In newer version also 4.x, this can only be set on only user setup.
Can't set this on group level.

Password Aging & Account Lockout in ACS 4.2

I have a requirement that in ACS the user accounts should get disabled after 1 day , so in the group setting under the Password Aging Field I configured the same as 1 day , the Grace & Warning Period is 0 days
I want that all these user accounts would be active for 30 days , and the moment the account is used (i.e the Start Message appears in the Radius Accounting ) then after 1 day from the usage then as per the Password Aging Rule the account should get expired.
Now my query is this password aging rule will start from the day I create the account in the ACS or from the day the user logs in.
I don’t want to use the Account Lockout Tab as I don’t know when the guest account would be used.
Request someone to help pls clarify my doubt.
Regards

Hi Yusuf,
Password Aging on ACS will just prompt to change the password. it will not disable the account.
The Account is present on the AD. So the Disabling and lockout features for an account will come from the AD.
I don't think a change in password for a guest account is what you would want to do.
Also according to me disabling the account should be a feature only for the AD admin and not open. A lockout can definately happen but that also has to be defined on the AD.
The link to password Aging on ACS is as follows:

Strange username in failed attempt log in ACS

I have an access point configured to use dot1x (MS-PEAP) which authenticates against ACS. Everything work fine, but there are some strange logs appearing in failed attempts. I think it is some sort of misinterpretation in ACS.
My ACS is 4.1
My access point is AIR-AP1231G version 12.3
I also have attached the logs. Hope anyone can help me clarify this.

This document provides a sample configuration for LEAP or MAC authentication.
Note: This guide assumes the most basic configuration. It does not cover configuration of more advanced encryption modes such as Cisco Key Integrity Protocol (CKIP) and Cisco Centralized Key Management (CCKM).

Event 4740 Not Logged for a Single Account Lockout

Domain Functional Level: 2003
PDC Emulator: 2008 R2
Lockout Origin DC (also the RADIUS server): 2003 R2
For quite a while now I have been relying on Event 4740 on the PDC Emulator to track account lockouts. Usually when the RADIUS server causes an account lockout, the Caller Computer Name is blank in the Event 4740. This usually tells me that our
Cisco WLAN Controller caused the lockout.
Our Default Domain Policy is set to audit Account Logon Events for failure, Account Management for success/failure, and Logon Events for success/failure (plus numerous other things).
This time there is no Event 4740 for this account lockout and I can't figure out why. The events are there for other lockouts several minutes before or after this one. Windows just hates me so it decided to skip this one. The main reason
this is a problem is because I just set up Scheduled Task on the PDC Emulator, triggered by Event 4740, to run a PowerShell script that will provide the help desk with a report for each account lockout, even parsing the IIS logs on the Client Access Server
to identify which ActiveSync device caused it. Of course the week after I announce that, Windows decides not to log one.
Using LockoutStatus.exe I determined that the Origin DC for the lockout was the RADIUS server.
NetLogon debug logging is enabled on the RADIUS server, however I took a nap today after being let out of work early for the holiday so by the time I checked the netlogon.bak file it had already been overwritten with newer data.
There was, however, an Event 644 locked on the RADIUS server (pasted below with domain/computer/user details edited for privacy). I don't even know where to start as far as trying to prevent this from happening again. Anyone have any suggestions?
Within the next couple months I will spin up a 2012 RADIUS server and a separate 2008 R2 DC to replace the 2003 multipurpose server, but it's not high on my boss's priority list so it's a tough sell considering the WLAN is functional right now.
Event Type: Success Audit

Hi,
I suggest you use Auditpol command to check the current auditing status on Domain Controller.
You can type this command below:
Auditpol /get /Category:Logon/Logoff
If the Account Lockout subcategory is set to no auditing, please use /set option to enable auditing:
Auditpol /set /Subcategory:”Account Lockout” /Success:enable /Failure:enable

Anyone know's how to make isight camera take snapshot for failed login attempts ?

I want my macbook pro to take pictures with the isight camera when someone has a failed login attempt ; anyone know of any programs and or apps ? I've searched all over & even called apple support and no luck.
Thanks !

If I want to count the number of failed login attempts what might be the best course of action?
Off the top of my head I figure I could:
Have a session variable that counts up to number X
Have a cookie variable
Insert the users IP address into a database table for each failed attempt and when the form loads I check to make sure there aren't X number of strikes in the last 30 minutes.
A combination of those might be a good idea. Most hackers are, luckily, amateurs with one-track minds. Create a database table to log failed login attempts. For every failed attempt, log at least the datetime, IP, sessionID, username (which should be unique on your site), reason for failure and failure count.
In a query following a failed login, verify whether the IP, sessionID or username match any in the failed_login table, and, if so, whether the current datetime is within, say, 12 hours of the last failed login. If yes, increment the failure count by 1. If no, insert a new row in the table.
Use client-friendly messages to inform your visitors why their login fails. Study failed logins for common patterns. It just might be that you are the culprit, and that you have to improve your login design. There is one good reason for doing all that. Then you will know that those in your failed_login table really had it in for you.
If your site traffic is high, then consider archiving old data. Throw nothing away!
