Clearpass Guest MAC caching - cannot connect again from the same device

  • 1.  Clearpass Guest MAC caching - cannot connect again from the same device

    Posted Oct 02, 2017 09:34 AM

    I am testing Clearpass guest with MAC caching and self-registration.  I have been using an iPad to test.  I have followed the setup using the Clearpass Workshop Series

     

    The guest mac caching is working now since I added "Allow All MAC Auth" to the authentication method.  Now when I test with my iPad, after the account expires, I cannot re-connect to my guest SSID unless I delete the iPad from the endpoint's database.  Is there a way to delete the endpoint from the database after the account has expired or is there a better way that I am missing?

    In your enforcement policy remove the amount of unique-devices per user allowed

    Victor,

     

    Thanks for the quick response.  Do you mean under the "Role"?

    You can either increase the amount of unique devices allowed per user or remove the rule if you think that enforcement is not needed

    Hmm, I took it out of the role completely and it still won't let my iPad on.  I wouldn't expect it to be an issue with unique device count since I'm using the same device repeatedly, correct?

    Are you using different names every time you register?

    What do you see in access tracker when your authentication fails ?

    I think I may have found the issue.  I checked access tracker and the client was getting assigned the [Guest] role instead of getting the default [Deny Access Profile].  I removed the second condition on the Enforcement Profile and that forced the client to get the Deny Access Profile and get now it gets the Captive Portal Page.Capture.JPG
