Active Directory and ACS 5.2.0.26

I want to create an SSID that will only allow teachers to authenticate at my school.  Is this possible using ACS?  In other words can ACS allow only certain groups in AD access to a particular SSID or subnet?

Thanks for any suggestions.

In order to restrict access for a specific AD group to specific SSID this is what you need to perform.

When the WLC sends an authentication request to the  ACS, it will include  the SSID that the user is connecting to, in the  attribute  Calling-Station-Id(31). We can use this information to create  multiple  rules in ACS 5.x in order to take actions based on the  information  contained in the attribute.

Under the  Users and Indetity Stores > click on Directory Groups > select  > check the group name you want to add and hit ok. Save the changes.

We  just need to  create a DNIS rule that includes the name of the SSID and  use it as a  condition in any rule that we create for authentication.  The * is  required because the attribute not only contains the SSID but  also a MAC  address so the * is use as a regular expression.

Now go to access-policies > default-network access > identity should be AD1.

Go  to authorization > click on customize > move the  AD1:ExternalGroups and end-station filter attribute on the right side  and hit ok.

After that slect the appropriate ad group for teachers and end-station filter.

Save changes.
