Setting up Prime Infrastructure to manage 2504 WLC, trying to add Lobby Ambassador and I get this error message:
User add failed : Some unexpected internal error has occurred. If the problem persists please report to the Tech Support.
Technically, this is my second attempt at setting up PI. I set it up initially with the wrong version of PI and created a lobby ambassador. I followed the instructions from the forum with a similar problem that said to remove the trap receiver on the WLC from my first attempt at installing PI.
I'm now able to add a Lobby Ambassador as long as its not the same username that I created on the previous PI setup. So I suspect this Lobby Ambassador username is somewhere on the 2504 WLC, but I can't find it anywhere to remove it.
I had the same problem. At first I try a link you posted, but this workaround failed.
Second I did:
no, your idea is not correct. As I wrote in my previous post, you can do anything (point No. 3).
I changed user to controller group and it simply works.
I have fresh news, I had successfully login with lobby ambassador accout, & had create guest user.
I have just been struggling with a similar issue on a fresh install of Prime 2.1 Upgraded to 2.1.1.
If I try to create the user with lobby ambassador role it just fails with "unexpected internal error".
I eventually found that by creating the user as a normal admin user first - the user is added. You can then go in a remove the admin role and change the role to lobby ambassador. This works with no internal error and the lobby admin user is working fine.
I would say it is just a bug.
