Supported devices/users on Cisco ACS 4.2

Hi,
Does anyone know how many devices/users does Cisco ACS 4.2 support ?
I need to know this information for a very large deployment.
Regards,

Hello,
The following items are general answers to common system-performance questions. The performance of ACS in your network depends on your specific environment and AAA requirements.
•Maximum users supported by the ACS internal database—There is no theoretical limit to the number of users the ACS internal database can support. We have successfully tested ACS with databases in excess of 100,000 users. The practical limit for a single ACS authenticating against all its databases, internal and external, is 300,000 to 500,000 users. This number increases significantly if the authentication load is spread across a number of replicated ACS instances.
•Transactions per second—Authentication and authorization transactions per second depend on many factors, most of which are external to ACS. For example, high network latency in communication with an external user database lowers the number of transactions per second that ACS can achieve.
•Maximum number of AAA clients supported— ACS has been tested to support AAA services for approximately 50,000 AAA client configurations. This limitation is primarily a limitation of the ACS memory.

Netscreen firewall authentication by Cisco ACS

Since Netscreen firewall only supports RADIUS authentication, is Cisco ACS server able to support it? If yes, which version and where can I find more info about it?

If it supports RADIUS then ACS should be able to support it.
I belive the latest version of ACS is V6.33, you can download a trial version from this site.
All the information you require should be here:

Cisco ACS 5.2 with NX-OS devices (Nexus) - User issues

Hey Community, I am having a really strange issue with Cisco ACS 5.2 and NX-OS Nexus Devices.
I create an account on ACS, let's call it User1, and give it privilege 15. With User1, I'm able to access on all of our IOS, IOS-XE, ASA, and PIX devices with privilege 15.
When I use that same User1 account into our NEXUS devices, I do NOT get privilege 15 access. As you probably know, NEXUS devices have roles: pre-defined or custom-made roles. So I assumed I would get the role of 'network-admin' (priv 15 read/write) with User1 when logging in, but instead I get the role of 'vdc-operator' (priv 1 read-only).
So then I tried to tweak User1 and give it network-admin under Shell profile >> Custom Attributes. I logged into the NEXUS and sure enough I was able to get network-admin access. However, my access to ALL the other devices (IOS, ASA, PIX, etc) doesn't work AT ALL! I'm not even able to log in with my username and password to these devices.
Has anyone ever run into this problem? Please Help!
Thanks,

ACS support Kerberos User Database?

Hi,
I've a customer currently having kerberos user database. I proposed to him to implement ACS to enable 802.1x on wireless client. Can ACS support or integrate with Kerberos User Database? If yes, any user guide which list out the steps on doing so?
I searched through Cisco website but failed to find any info related to the integration of ACS with Kerberos User Database.
Thank.
Delon

For network users who are authenticated by a Windows user database, Cisco Secure ACS supports user-changeable passwords upon password expiration. You can enable this feature in the MS-CHAP Settings and Windows EAP Settings tables on the Windows User Database Configuration page in the External User Databases section.

User authentication in Cisco ACS by adding external RADIUS database

Hi,
I would like to configure the below setup:
End user client (Cisco Any connect/VPN client) -> ASA 5500 (AAA client) -> ACS server -> External RADIUS database.
Here ACS server would send the authentication requests to External RADIUS server.So, i have added the external user database (RADIUS token server) in
ACS under External databases.I have added AAA client in Network configuration (selected authenticate using RADIUS(VPN 3000/ASA/PIX 7.0) from the drop down.
Here how do i make ASA recognize that it has to send the request to ACS server. Normally when you use ACS as RADIUS server you can add an AAA server in ASA and test it.But here we are using an external RADIUS server which has been configured in ACS, so how do i make ASA to send the requests to ACS server?
Any help on this would be really grateful to me.
Thanks and Regards,
Rahul.

Thanks Ajay,
As you said nothing needs to be done on ASA side, if we are using an external user database for authentication.
Im a newbie to ACS and this is the first time i'm trying to perform a two factor authenticaton in Cisco ACS using external user database.
By two factor authentication i mean, username + password serves as first factor (validated by RADIUS server), username + security code (validated by RADIUS server) serves as second factor.So, during user authentication i enter only username in username field and in "password" field i enter both "password + security code". Our RADIUS server has already been configured with AD as user store, so we dont have to specify AD details in ACS. I have done the following in ACS to perform this two factor authentication.
-> In external user databases, i have added a external RADIUS token server.
-> In unknown user policy , i have added the external data base that i configured in ACS into the selected databases list.
-> under network configuration, i have added the Cisco ASA as AAA client (authenticate using RADIUS (Cisco VPN 3000/ASA/PIX 7.x+)).
Just to check whether user authentication is successful, i launched the ACS webVPN using https://IP:2002, it asked me to enter username and password. So, i entered username and in password field i entered "password + security code". But, the page throws an error saying "login failed...Try again".I cant find any logs in external RADIUS server.
Here is what i found in "Failed attempts" logs under Reports and activities.

RSA SecurID and Cisco ACS integration for user(s) with enable mode

I thought I had this problem figured out but I guess not.
I have a Cisco 2621 router with IOS 12.2(15)T17. Behind the
router is a Gentoo linux, RSA SecurID 6.1 and Cisco ACS 3.2.
I use tacacs+ authentication for logging into the Cisco router
such as telnet and ssh. In the ACS I use "external user databases"
for authentication which proxy the request from the ACS over
to the RSA SecurID Server. I installed RSA Agents with
sdconf.rec file on the Cisco ACS server. I renamed "user group 1"
to be "RSA_SecurID" group. In the "External user databases" and
"database configurations" I assign SecurID to this "RSA_SecurID"
group.
Everything is working fine. In the "User Setup" I can see dynamic
user test1, test2,...testn listed in there as "dynamic users". In
other words, I can telnet into the router with my two-factor
SecurID.
The problem is that if test1 wants to go into "enable" mode with
SecurID login, I have to go into "test1" user setting and select
"TACACS+Enable Password" and choose "Use external database password".
After that, test1 can go into enable mode with his/her SecurID
credential.
Well, this works fine if I have a few users. The problem is that
I have about 100 users that I need to do this. The solution is
clearly not scalable. Is there a setting from group level that
I can do this?
Any ACS "experts" want to help me out here? Thanks.

That is not what I want. I want user "test1" to be able to do this:
C
Username: test1
Enter PASSCODE:
C2960>en
Enter PASSCODE:
C2960#
In other words, test1 user has to type in his/her RSA token password to get
into exec mode. After that, he/she has to use the RSA token password to
get into enable mode. Each user can get into "enable" mode with his/her
RSA token mode.
The way you descripbed, it seemed like anyone in this group can go directly
into enable mode without password. This is not what I have in mind.
Any other ideas? Thanks.

CISCO ACS, How to Limit User Session ?

Hi Guys,
hope you would help me,
how to limit the user session in ACS 5.x ?
i'm aware the menu on
Access Policies >Max User Session Policy > Max Session Group Settings
i already set the global value to 1, Max Session for User in Group to 1, and Max Session for Group to 1.
so it means the user only could open 1 connect at the same time right?
the problem, it didn't works.
i had 1 ACS 5.5
2 CISCO Cisco IOS Software, 3700 Software (C3725-ADVENTERPRISEK9-M), Version 12.4(15)T13, RELEASE SOFTWARE (fc3)
(let's call it R1 and R2 )
i'm trying to telnet both of them at the same time, and it works ( it means the session limit didn't works, cmiiw )
i already include :
radius-server attribute 44 include-in-access-req
radius-server host 192.168.217.98 auth-port 1645 acct-port 1646 key somekey
on the line vty :
accounting connection acs
login authentication acs
am i missing something?
also, is this feature works on tacacs+ too?
Thanks,

Dash,
You can leverage the group mapping feature where members of a certain AD group are mapped to a local group in ACS with the max sessions defined.

Cisco ACS 5.4 + Anyconnect 3.1 NAM with 802.1x, problem with changing ACS Radius user password

Dear all,
Presently, we are testing 802.1x using Cisco ACS 5.4 and Cisco Anyconnect v3.1 as 802.1x supplicant. We have created predefined NAM profiles (with Cisco Profile Editor) and applied as default in on our test machine. We are using PEAP (MsCHAPv2) and ACS local user credentials for authenticating process. We have noticed that, when we try to authenticate the network with predefined profile (network profile has Administrator Network privileges) and Windows user on test machine has no Admin privileges we are not able to change ACS user password (checked "Change password on next login" in the ACS user profile). In the Monitoring and Report View we get Failure Reason "24203 User need to change password" but no popup window apears in Anyconnect. When we change Windows local user privileges to Admin or create Anyconnect network profile localy (privileges User Network) then, we are able to finish the process.
Have you ever been facing the problem described above. Is it Anyconnect bug? How can we fix it?
Best regards,
Piotr

If this happens with all machines then if a microsoft guy can look the app logs/privileges. It seems the app is requesting privilege that it is not authorized to and that's why the propmt window fails to appear. If we know what that privilege is we can probably fix it. If that privilege is not even required for smooth work Cisco need probably to fix this behavior.
I am sorry if I am not able to help but I am not using the anyconnect for production.

Amjad

Cisco Works "Devices not configured in ACS"

Hi!
I have instaled Cisco Works ver. 4.3.1
I have added using the Device Discovery, my devices. Some of them where not configured already on ACS with the loopback address, that was the one on the discovery configurations. Because of that, i could not manage those devices, althoug i could authenticate on them. I then updated the ACS with the loopback address, and configured the router's to authenticate using the source-interface of the loopback.
The problem is that i keep not being able to manage this devices on the cworks, because the are still as "Devices not configured in ACS".
Can anyone help me here?
Regard's
Miguel Amaral

Hi,
This happens, when you integrate the ciscoworks with ACS and Router/switches not configured with ACS. Try to reconfigure the device in ACS, try removing and adding it again in common services...Try for a single device and check it out... Try stopping/starting cw services after that // net stop crmdmgtd, net start crmdmgtd. Revert with the results..

Need to Create More Options in Cisco ACS 5.2 User section

Hi Team,
I Need to create more options on Cisco ACS 5.2 under internal identity store in users. please help how to do add, default not showing all.
i have seen on internet. attaching doc.
Regards
MR

To create additional attributes for internal users do the following:
- go to System Administration > Configuration > Dictionaries > Identity > Internal Users
- Press Create to define the additional attributes you require
For each attribute can
- define the type
- give a default value. This will be applied to all existing users and appear as default when new user is created
- indicate whether the attribute is required and must be defined for each user
- define a policy condition. If define such a condition will appear as an option when customize rules in a policy

Cisco PI 2.0 supported devices

hi all,
I need to install cisco PI 2.0 and I have Cisco switches 2950 in my network. do this model is supported on Cisco PI2.0 or not?
i searched on the supported devices excel sheet but I did not get any result
please advice.

Check the Attached Excel file for PI 2.0 Compatibility, check the Detailed Device support matrix tab you will find. it is supported.

Cisco ACS 4.2 one user in multiple local groups

Currently i have group mapping like this
ACS Groups           Window Groups
    Grp-A-B             Grp-1 and Grp-2
    Grp-A                        Grp-1
    Grp-B                        Grp-2
For example currently one user test1 is part of both groups 1 and 2 in windows and is mapped to Grp-A-B in ACS. Is it possible if i delete the Grp-A-B mapping in ACS and can see the user test1 speratley in both groups ( Grp-A and Grp-B) in ACS?

Salam Muhammad,
If you have a local user in ACS, that user can not be a member of two groups at the same time.
The same concept applies to the external users. They can not be mapped to two different groups at the same time.
If you remove the Grp-A-B configuration, the user test1 will be mapped to the first group in the list because ACS 4.2 process the goup mapping in order:
'''snip'''
Group Mapping Order
ACS always maps users to a single ACS group; yet a user can belong to more than one group set mapping. For example, a user named John could be a member of the group combination Engineering and California, and at the same time be a member of the group combination Engineering and Managers. If ACS group set mappings exist for both these combinations, ACS has to determine to which group John should be assigned.
ACS prevents conflicting group set mappings by assigning a mapping order to the group set mappings. When a user who is authenticated by an external user database is assigned to an ACS group, ACS starts at the top of the list of group mappings for that database. ACS sequentially checks the user group memberships in the external user database against each group mapping in the list. When finding the first group set mapping that matches the external user database group memberships of the user, ACS assigns the user to the ACS group of that group mapping and terminates the mapping process.
