have sql server access another system to authenticate users.

[tekkerguy]

Is there any way to have sql authenticate users by accessing a different database with user logins and passwords?

We want to use sso to authenticate to the sql analysis services, but we don't want to create a new user in sql for every user in our database (which I believe is oracle, not sure because the company is huge, and I haven't ironed out the details yet).

So, user logs into website, website accesses analysis services, which would then access another site or database to authenticate, not sql's authentication and not windows authentication.

Is this possible?
