Symptoms
A customer can not login to the OBAS CP. Although the credentials entered are correct, he/she receives "Session expired due to inactivity" error messages when submitting the login form.
Cause
The issue is caused by the customer's IP address changing. If the customer's IP address changes during the session, the customer is caused to be logged out and cannot successfully log in again (i.e. using new IP address) without manually clearing browser cache/cookies.
