i have a WCF service(hosted in IIS) with the following configuration:
basichttpbinding
MTOM
Streaming(for file upload and download)
now i want to implement a security system where i receive username/password
only once. after which i want to issue a custom generated token which should
be used for all subsequent calls to service. i also want to control the
expiration and renewal of the issued token. what should be my approach in
order to acheive this?
please advice, if possible with some code sample.

Hi Sarasam,
You need to use Federation binding and implement an STS that will
issue the token. You can then use an authorization policy and/or
authorization manager with your specific service, and with the service
you can define MTOM for encoding.
