Hi Asok,

This comes with the behavior of SSO.
When you register travelocity.com as a service provider in IS and point
travelocity.com webapp to use IS as the identity provider, authentication
process of webapp is totally handled by IS.
Even the page you enter username/password is submitted by IS. Webapp does
not have any idea on the valid user name and password of the user trying to
login as all these details are captured and authenticated at IS side. IS
then just let the webapp knows whether the user is authenticated or not.

This helps to keep the user passwords in a secured centralized place than
saving it in each webapp and helps to provide a better user experience by
not asking users to type username/password several times(If you are logged
into IS, you are automatically logged into travelocity.com as well.).

Therefore any other user in IS also can login to travelocity.com webapp
with his/her credentials.
This article[1] will provide more insight.
Hope this helps.
