Forum .LRN Q&A: Login to dotlrn from an other site

Hello together!

We want to login out of our Homepage with the login mask from dotlrn. A timeout-massage will be shown if the user wants to login into the plattform.
Dotlrn wants the user data again, the problem is caused by the HASH-ID and the TIME-ID.
How it can be related that the user can automaticly login, without a step before(timeout massage).

We need a solution for this problem.
Can anybody help us ?
