Hello Collin!
Thanks for reply but the client cannot go to 6.5... they got some legacy controllers, some 3400s
I tried doing this but didnt work
https://community.arubanetworks.com/t5/AAA-NAC-Guest-Access-BYOD/How-to-display-custom-error-messages-on-a-weblogin-page/ta-p/271994
Then someone on TAC told me a easier way to send a custom message which was the way i said in first message, but was just wondering if there is if thats was the only way. The only thing with the way the tac told me is that it input a entry on my my endpoint database with social media information, and if the user go to IT department to get his device added because he changed his laptop or trablet or whatever, they might need to manually blacklist the user and then unblacklist so accelerate the process. I mean it has another role that the only thing that does is showing the error message and he wont get the login again untile he change of role, thats the only downside i see of that.
The thing i like is that it shows a nice message.
I just wanted to have different options to show the client.
Cheers
Carlos
