Cisco AAA/Identity/Nac :: ACS 4.2.1 Authentication And Database Replication?
Mar 27, 2011
Firstly the ACS 4.2.1 for Windows database replication does any one have and documentation on the processes required?Secondly I have a single system installed which is providing TACACS authentication for management access to a Cisco 5508 WLC, the controller prompts with a login box on connection to the web interface. When you put in the username and password pair the box comes back as if the authentication has failed. On the ACS I was unable to see any failed authentications so enabled passed authentication reporting and can see the user passing the process. The WLC is running software version 6.0.199.4. On the ACS I have added the extra two options within the TACACS interface configuration and have a ‘role1=all’ against both the user and the group the user is part of so I am confused as to why the user is still denied access.

I am not able to replicate Database between two ACS SE 4.2. I am getting the following error:
Inbound database replication from ACS 'ACS_BEX_001' denied - shared secret mismatch.
The configuration apparently is ok. I am attaching the configuration from both ACS.

Just upgraded from 4.0 - to 4.2 then to 4.2.1 15. As you may have seen with periovous posts of mine its not been an esay ride.I have now managed to get it all working - backups AAA etc but for some reason i cannot get the replication to work! Its states the following...
Within the Database Replication active log - Error OutBound database replication failed - refer to CSAuth log file.Other lines in the log state its ok eg - Component logging reports was updated - being replicated to slave...
Please note that the $ is a symbol that i have used because the symbol in the log is strange and i cannot seem to be able replicate here with this text, for example $etworks - should be networks.

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?

We have recently upgraded acs 5.1 to 5.3 ( normal upgrade process), all secondary (ACS-B) was deregistered from primary (ACS-A , used as configuration server and log collector) and updated successfully. But while upgrading primary acs server was rebooted manually. But later primary server was re upgraded successfully to 5.3.
Just to ensure database is not lost on primary acs (ACS-A) , primary acs was registered to one of the secondary acs (ACS-B). Initially ACS-A registered with ACS-B, both ACS was showing proper role now. ACS-A ( secondary ) and ACS-B (primary). But on New primary ACS (ACS-B) is showing new secondary (ACS-A) offline and replication pending. Whereas on Secondary ACS-B its shows primary ACS-A online and updated. But ACS replication id is gradually incrementing. ACS system is in this system for last 2 day, But not sure if there is real replication happening at backend? How long it take place to replicate completely? and how to check / verify status of upgrade?

on the dashboard of the "Monitoring & Report Viewer" I see a lot of system alarms related to the database.The explanation of the alarm says to look at the Collector logs for the details.

i'm trying to configure acs 5.2 to LDAP external idenity store, when LDAP failes ACS 5.2 should use internal indenity store. I configured A sequence to use LDAP 1st then Internal and i shut off the link to the LDAP but ACS will not use internal, AAA Diagnostics keeps telling me that Cannot establish connection with LDAP server and will not use the internal store.

I am working on project with Secure ACS 5.2. I am trying to determine the proper External Database to use. LDAP or direct to AD?
Additionally, the Domain that I am connecting to has Multiple sub domains. All of the users are currently in the Sub domains, but will be moving to root domain later. How should I configure the connection, do I need to connec to each sub domain or can I just connect to the root?

On Cisco ACS 5.2.0.26 Patch 10, I got this system alarm:Incremental backup is not configured. Configuring incremental backup is necessary to make the database purge successful. This will be useful to avoid disk space issues. View database Size is 2.92GB and size it occupies on the harddisk is 2.91GB
In "Monitoring Configuration > System Operations > Data Management > Removal and Backup", we got this information:
Database Purging:If database size exceeds 120 GB, a backup (if configured) and purge will be initiated. If database size exceeds 150 GB, a purge will be initiated.
Could View database size reach 120 GB ?I want to know how long will Cisco ACS works without problem and if I need to hurry to configure purge.

I am running windows based acs 3.3 in my lan environment going to be replaced with acs 1120 appliance running acs 4.2.1.15 , ACS 3.3 database has been built upto 4.2.0.124 ,step by step by upgrade process
1) acs 3.3.3.14---> 4.1.1.24
2) acs 4.1.1.24 ----> 4.2.0.124 .
now my database is with 4.2.0.124 dmp file , I cannot upgrade my database to 4.2.1.15 because 4.2.1.15 patch is not applicable & executable on 90 days evalution package of 4.2.0.124 of windows platform .
can i import my windows based 4.2.0.124 datbase directly to my acs appliance running 4.2.1.15.3 ??? , else its requires any step to be done to modify the windows based databse matching to appliance windows verison once .
I could see on appliance under restore settings the following options (restore from 4.2.0 backup file to acs 4.2.1)

i am running NX-OS image n5000-uk9.5.1.3.N1.1.bin on the nexus 5020 platform.i have configured authorization with tacacs+ on ACS server version 5.2 with fall back to switch local database.a user test with priv 15 is craeted on ACS server, password test2 everything works fine, until i create the same username on the local database with privilege 0. ( it doesnt matter if the user in local database was created before user in ACS or after ) e.g.: username test password test1 role priv-0 (note passwords are different for users in both databases)
after i create the same user in local database with privilege 0,if i try to connect to the switch with this username test and password defined on ACS, i get only privilege 0 authorization, regardless, that ACS server is up and it should be primary way to authenticate and authorizate the user.

I am configuring new ACS 1121 appliance with version 5.3 and wanted to know how to configure Remote Database settings in ACS5.3 Is that necessary to configure that option ?
Also one more thing I can see that ACS 5.3 generates lots of logs is there any solution to reduce such logs. It seems many unuseful logs which are system related are getting logged into device which might no be good for memory requirements of device.

I have a weird issue. I recently setup an ASA 5510 and had SSH working. To make it easier on my VPN users I then decided I wanted to setup a Windows 2008 Network Policy Server for RADIUS authentication. Ever since I added the RADIUS part to aaa authentication, when I use SSH to connect to the ASA it will not take the local user name and password I have setup. I can however get in using a Domain user name and password. Below is the SSH and AAA configuration. Am I missing something here? The username and password in the ASA is not on the domain and it's like the ASA is not even trying LOCAL when it tries to authenticate. I want it to use the local username and password if possible. I'm kind of new to ASA's..
On another note, I have never been able to SSH in on the internal interface. I always get a "The remote system refused the connection" error message. I can only use the outside interface.
Site-ASA# sh run | in ssh
aaa authentication ssh console SERVER_RADIUS LOCAL
ssh 0.0.0.0 0.0.0.0 outside
ssh 0.0.0.0 0.0.0.0 inside
ssh timeout 60

I configured before ACS v4.2 to authenticate network devices using internal users at first, and if the user is not found use AD list users. But with v5.3 I have some problems doing this, on identity policies I use rule based result selection option, I configured 2 polices for Identity source, one for Internal Users and other policy for AD user, but it only works with the first policy, internal users or AD, but works only for the first policy identity. how to do that, if the user is not found on first policy, continue to the next policy.

I need a specify users to allow access to particular devices and give privilege only for show command or show run. Here is how I tried to configured.
1. Configured two seperate Shell Profile and Command set with privilege level 4-5 and allowing only show run command
2. create seperate service selection rule with adding the require NDG and protocol TACACS and maching service "RestrictAccess"
3. In the RestrictAccess Service I have following configured; Identity: internal users, Group Mapping to a particular group where the user exists, authorization: matching the above created identity group, NDG, shell profile, command sets
All the steps are attached in the .doc file. However when I tried with the particular user he is able to access everything and he is not hitting the correct access rule.

In order to restrict access to websites on our internal network, would we be able to put an ASA in front of the web server and force users to authenticate through the ASA and, once authenticated, allow only port 80 or 443 traffic for that use? The ASA would query the ACS 5.1 server for authentication/authorization using AD as the identity store. Is this even possible with TACACS?

My customer has a large installed base of MACs, all connected via controller-based (5508) WLAN. He wants to grant access to the network based on the device's mac addresses and move the WLAN-clients to a specific VLAN.I added all devices with their mac addresses to the ACS internal identity store for hosts.According to the following message the client sends the user-login credentials (chegger) within the RADIUS-request instead of the clients mac address and of course it has to fail. After many configuration changes, I ended up always with the same result.

I have question on EAP-TLS with ACS 5.2. If I would like to implement the EAP-TLS with Microsoft CA, how will the machine and user authentication take place? Understand that the cert are required on both client and server end, but is this certificate ties to the machine or ties to individual user?
If ties to user, and I have a shared PC which login by few users, is that mean every user account will have their own certificates?
And every individual user will have to manually get the cert from CA? is there any other method as my environment has more than 3000 PCs.
And also if it ties to user, all user can get their cert from CA with their AD login name and password, if they bring in their own device and try to get the cert from CA, they will be able to successfully install the cert into their device right?

We got recently a Cisco Secure ACS 1120 and i upgraded the Appliance to 5.1 from 5.0 with all your support
Now I need to integrate Cisco ACS 5.1 with RSA Authentication Manager 6.1 . I Successfully Downloaded config file from RSA ACE Server and exported into ACS 1120.
I also Added ACS as a NetOS Agent in the RSA Server , during the process i found few warnings . The ACE Server is not able to Resolve the IP Address to NAme ( DOes it Necessary ?? ).
I havent created any secret Key file for communication between ACS and RSA and encryption i used is DES.
Now when I log into ACS and search for Devices in the Identity Store Sequences i am not able to Look for RSA Token Sever .
