[SR-Users] diameter auth with round trip

[JB]

Thanks for the suggestion about auth_diameter, do you think there would be
an interest in the community if we were to do this modification on ims_auth
or auth_diameter ? could it be integrated to trunk ?

We do not want to publish our own fork of ims_auth or auth_diameter with
that small change and maintain the code repository if it can be avoided, so
it would be nice if we can put it in the trunk and forget about it. Plus it
is more open source oriented to publish to main branch i feel :)
