Segregating Wireless User from regular AD user

Hello,

To get rid of account lockout problem that happens due to an account being configured in Android or IOS devices, I am thinking of segregating such users from regular accounts that are normally used to login to domain through computer account. Probably we can enable password never expire for such accounts and disable their login to all computer (default setting). I am not sure if there can be other GPO settings that can put in more restrictions on those user accounts. I do believe this may reduce the security risk of compromising a regular account that is a member of local administrators group in their respective computers. 

Anyone has done that? I believe it is already implemented by many. If anyone can share their experience or points that need to be considered, it will be really great!

Regards, Anupam

Fine Grained Password policy may be useful if you’ve a select few with these issues and you have DFL to support it.

Just use Radius for the authentication on the wifi, and enable radius lockout on the radius server.

And make sure the number of invalid attempt for the RADIUS server is less than that for AD.

I've always assumed the behavior to the end-user would be the same. Can you elaborate how the RADIUS lockout behaves differently (and better) than an AD lockout?

 

Anupam, the trick we've discovered which drastically reduces (but didn't completely eliminate) mobile device account lockouts, is to set the password policy Enforce Password History setting to "2" remembered passwords rather than 1. Thus a password change

does not cause the old saved password to count against the bad password count, which triggers the lockout condition.

The RADIUS lockout is limited to trying to connect via the RADIUS server. So if you set the lockout to be 4 attempts on the RADIUS server and 6 on AD, once you

lock yourself out of RADIUS, any more attempts will not be passed to AD. Connecting to AD via other methods  (like logging into a domain joined computer) will not be affected by the RADIUS lockout..
