We are using a sponsor based guest captive portal. Guests fill in the form on the captive portal and enter the e-mail address of the sponsor, after which the sponsor gets an e-mail prompting him to authorize the guest request. After authorization the guest gets access to the guest wifi network.
This works just fine in our Clearpass virtual appliance version 6.6.8.
Yesterday we upgraded the appliance to version to 6.7.1. After the upgrade all the settings seem to be just the same as before the upgrade, but somehow the mails related to the sponsor/guest receipts are no longer being sent.
I've checked my mailserver (internal mailserver) and I am not seeing any request coming in from my Clearpass appliance, which leads me to believe it totally Clearpass related.
When I go to the Messaging Server setup in the Profile Manager and send a test mail it works just fine and the test mail pops up in my mailbox. When I try to send an e-mail from the Guest manager environment it doesn't show up in my mailbox. No error messages are popping up in the logs also.
I've done a rollback (snapshot) to version 6.6.8 and everything works again.
Any ideas?
