Hi Tabish:

Unfortunately, there is no specific document for wireless authentication with ACS 5.x

If you wish you can check the below listed sections from acs 5.1 user guide:

You can configure AD on Windows to use as external database, you can use the following link to integrate your AD


For authorization using TACACS+


For configuring managing access

Hi Tabish,

Did you find out how to do it? I'm facing the same issue. I have WLC authenticate via ACS4.2 to AD, however I'd like to upgrade 4.2 to 5.1.

Please let me know if you found any useful info.

I could be wrong, but I thought that ACS 5.0 and 5.1 didn't work well with

AD '08.  ACS 5.2 is out that should work with AC '08

  • Cisco Employee,


When doing this setup please make sure you are running ACS or later due to a major issue with WLCs.

Only patch 6 or later versions work with WLCs.

Regarding AD 2008 support, please note that only ACS 5.2 supports all editions of:

Windows AD 2003

Windows AD 2008

Windows AD 2008 R2.

Please takea a look into this document showing how to integrate with AD and how to create the authentication flows (it shows switches as AAA clients, however the phylosofy is the same for WLCs):
