Integrate ACS verison 5.x

Yes. AD integration is a key function of all versions of ACS and is quite commonly deployed that way.

Windows Server 2012 support specifically was introduced as of ACS 5.4, Patch 2 (released February 2013). This is noted in the Compatibility Guide.

The configuration guide has details here.


Hi Marvin,Hope you're well!I

Hi Marvin,

Hope you're well!

I am facing some access issue after completed the ACS (5.1) and AD (Windows 2003) integration, details underneath.

Enable password for (Router, Switches) is working fine if identify source is "Internal Users", unfortunately after completed the integration between ACS to MS AD, and change the Identity source to "AD1" I got the following result

1. able to access network device (cisco switch) using MS AD username and password via SSH/Telnet.

2. Enable password is not working (using the same user password configured in MS AD.

3. When I revert back and change the ACS identity source from "AD1" to "Internal Users" enable password is working fine.

Your device-side setup looks

Your device-side setup looks fine. I suspect it's on the AD or ACS-AD end.

Have you had a look at the configuration guide example for ACS-LDAP here? It has some tips on verifying the ACS-LDAP connectivity.

Once you've confirmed the simple ones there are check out OK, we can look more closely at what remaining issues (if any) you might be seeing.
