Cisco ACS 3.1 Database Replication error

I set up two new Cisco ACS servers on Win2k and followed directions on setting up database replication. However, when I try to replicate the databases I get the following error message in the log:

ACS has denied replication request. I could not find any information on this error can somebody tell me what am I doing wrong.

Re: Cisco ACS 3.1 Database Replication error

This an authentication error. When primary ACS replicate the secondary one, it sends its ip as its idenfier and the password that you have defined for itself. So, if you go to Network configuration on primary server, and click on your primay AAA server (which is the machine itself) in the AAA Servers table, you will have the option to put your password. This is the password that it uses to authenticate with the secondary server. So, on the secondary one when you define the AAA server for this primary server, please make sure to enter this same password that you have define on the primay for itself. As primary server is replicating the secondary one, secondary server will authenticate the primary (0ne way authentication).

Please let me know if this ressolves the issue. Thanks,

Re: Cisco ACS 3.1 Database Replication error

I have the same issue. I have reset the keys to the same value and I still get the error message saying that the secondary is denying the replication. Is there anything else to check?

Never mind. I found an earlier post that has thesolution: Do not select the primary ACS sever on the secondary as a replication partner.

Re: Cisco ACS 3.1 Database Replication error

Thanks I got it to work. I had to take the Primary ACS server off from the Secondary Server as a replication partner. Now I am able to replicate database. However, if the primary server will go down and the secondary will handle authentication and I need to add a user to the secondary server how will it replicate if it is only set to receive updates from the primary. I tried to add a user to the secondary ACS server and it was not replicated to the Primary ACS server. It seem that you can not replicate from the secondary server. In ver 2.6 I was able to do so.

Re: Cisco ACS 3.1 Database Replication error

Hi, yes, you cannot define primary as your replication partner on the secondary server. Replication in both way is not allowed in ACS. It has be done in one way. All the configuration changes must go to one server (primary). In your case, the best you can do is, if/when the primary goes down, and if you need to make the changes on the secondary then primary came back, reconfigure your replication that is make the secondary as primary and primary as secondary, then do just one time manual replication. After that make the changes the back as it was before. Thanks, Mynul
