Etherpad integration with Moodle 2.8

[xjtluapp]

Hi
The etherpad can work properly, but when I try to integrate it Moodle using the Plungin,
It appears that the latest version etherpad has some compatible issues with Moodle plungin,

it reports like:
validUntil is in the past
according to the API, it indicates that session is not correct.

When I replace it with the old version etherpad(a backup server created 2 month ago) , it works properly.

much appreciate your support
