Symptom
When installing a fresh image of 2.6 on supported hardware, the ip-domain name field should have some input validation to ensure the domain is a valid domain. Currently, if there is an error, the installation wizard proceeds without alerting.
Conditions
ISE 2.6 Initial Setup: prepending dot (.) to the domain name when prompted
Workaround
Do not prepend period to the domain name. ISE will automatically add.
