Re: ACS Evo

Hi Guro,

ACS eval is a full software (for 90 days) and there is no license required for ACS windows. Once the 90 days period expires you need to reinstall full version of acs(need to purchase full version)



Do rate helpful posts

Re: ACS Evo

After you used the eval, you can backup your config and restore it on the full version so you dont loose any data

Re: ACS Evo

You have to configure replication of ACS.

There was a defect CSCsk64715 in 4.1 where manual replication worked for the AD group mapping but not auto replication. This is fixed in 4.2

AD group mapping can be replicated.

Documentation for configuring replication:

Make sure to read this section:

Replication of Network Access Profiles contradicts the replication of Network Configuration Device tables; therefore, do not check both of these components at the same time. NAP settings will override all other settings. Dynamically mapped users are not replicated, only statically added users are replicated.

Re: ACS Evo

Thanks for your i have read the doco now what i have understand is as follow:

secondry server will replicate username and passwords from primary server

primary server has windows ad where all the user is authenticated (current scenario).

now what if the server dies the primary one physical how secondry will get the info....all i am trying to get my head around as i am v new to this.....

Re: ACS Evo

the authenticated users remain authenticated, the failover will handle the new users that try to login.

Re: ACS Evo

you have to change the configuration, to make it not a partner anymore on the primary.

Did you read the configuration guide I sent earlier? It's well explained there:
