I'm hoping for some help with trying to authenticate Apple iOS devices via an Ironport S650.
I'm authenticating devices to the corporate network successfully with NPS, however I'm frequently encountering authentication failures.
In the authlogs I am seeing a number of messages such as:
Tue Nov 20 14:08:14 2012 Info: PROX_AUTH : - : Login for user []\[ipad@domain.com]@[DN6FXBA4DFJ1] failed due to [No such user]
Tue Nov 20 14:27:40 2012 Info: PROX_AUTH : - : NTLM CRAP authentication for user [DOMAIN]\[ipad] returned NT_STATUS_INVALID_WORKSTATION (PAM: 7)
Tue Nov 20 14:27:40 2012 Info: PROX_AUTH : - : Login for user [DOMAIN]\[ipad]@[DN6FXBA4DFJ1] failed due to [Invalid workstation}
I have configured the iPad to use the proxy server on port 80 and entered a valid username (iPad) and password. On launching Safari, I am repeatedly prompted for a username and password still.
Having done a little more reading, I gather that this is just the first of many issues I may encounter. As such, I'm keen to know if anybody has successfully deployed iPads connecting to the web via an Ironport appliance and if so what you would recommend.
Thanks,
Neil
