After upgrade to Enterasys NetSight and NAC from 4.4 to 5.1, sponsorship guest portal stopped working

[Charlie_Altherr]

The guest gets as far as the verification screen. There he sits forever, since no code is coming. The email and txt message that are supposed to be sent are now being rejected by our email server (Exchange). It appears that NetSight is now forcing authentication of those messages. The Exchange server is set to allow these messages anonymously, and so rejects the blank password in the auth exchange. Oddly enough, this action is only happening with the guest portal. Alarm and event notifications are still being successfully sent anonymously from NetSight. WireShark traces have confirmed this behavior. Again this behavior started with the upgrade to 5.1. Does anyone have a cure? Can the email messages sent via guest portal be modified to send anonymously as they did in the past versions?

Charlie,

Thank you for your inquiry. I am posting the solution for the broader audience.

After investigation, we have found that we are sending the Friendly User Name “Network Administrator” as the password to the email server. As a resolution, you can clear out the message string for “registrationVerificationEmailSentFromName”.

This will clear out the password we are sending to the email client.

Take care

Brian
