I see in my 5508 that it shows I'm not connected to AD. I test the connection and receive (clock skew error). I can see that my WLAN and ACS times are within 7 seconds https://community.spiceworks.com/topic/579625-cisco-acs-clock-skew-error apart. My DC time is 5 mins faster thought. I haven't had any issues like http://www.firstdigest.com/2011/05/acs-5-1-with-active-directory-integration-part-ii/ this in the past 2 years. Anyone seen this issue and have a way to resolve it?

Even your electronic wrist watch will gain or lose a few seconds a day cisco acs (and the clocks in computers are no better, usually much worse). Consider syncing everything with NTP.

You don't have to specify the source interface, but I prefer to do so. Then choose your 3+ time sources (internal or external): ntp source GigabitEthernet0/0ntp master 2ntp server 64.250.229.100ntp server 128.138.140.44ntp server 132.246.11.229 prefer Typically, you should have a specific NTP server on your network or use your gateway router to update externally from NTP pool. http://support.ntp.org/bin/view/Servers/NTPPoolServers Point your DC to update from that router and use your Windows W32tm with DOMHIER, built-in services to update your network. 0 This discussion has been inactive for over a year.

I described a little bit the installation process for Microsoft Active Directory. Now it's time to go ahead and talk about the ACS 5.x integration with AD. In the meantime I changed the version "5.1" to "5.x" as version 5.2 is already out there. This tutorials work for both versions. Maybe you are wondering why I don't have a separate chapter about the installation process of ACS 5.x. The reason is that the installation is pretty straightforward, as you can see below. You have to follow some instructions, add some mandatory information (IP address, username, password…) and you're done. Very simple. Because an image worth a thousand words, I took some screenshots during the process to make explanation more easy to follow. Load the ACS 5.x image and after the initial screen you have to see the following warning. YES is the correct answer. ACS 5.x will start the installation If everything goes well, you should see a screen asking to type the keyword "setup" Next, ACS 5.x will ask for some mandatory information: Next, ACS 5.x will install all core files and when done it will show a prompt to login. You can go ahead and login or open a web browser and type https://your-ip/acsadmin (in my case this would be https://172.31.82.8/acsadmin , according to the image above). You should see something like this: Default username: acsadmin and password: default. The system will require to change the default password: Last step, before system is operational, require you to add the license file. If you got the ACS 5.x image from Cisco website they will provide you with a trial license file or a standard / extended license , if your company already acquired one. If the installation part is very simple, the next lines I'm sure are critical for some of you. ACS 5.x is available for 2 platforms: bare metal system (that means a dedicated machine) or VMware appliance. If you are like me, then you don't have a dedicate machine for testing some ACS 5.x solutions and VMware can be difficult sometimes to install and operate. The next alternative, which
