Looking for a way to make all users having the same profile

[stefangiuros]

Dear all:
We have a set of Cognos 8.2 reports that are to be run in an organization with 1000+ users. One of these reports act as a "start page"; after the user is authenticated via username and password, the desired result is to automatically run this report. The rest of the reports are to be accessed by clicking buttons provided by the "start page" report.
I think we can define an user with a profile like this and copy its profile to all other users, user by user, but this is quite a difficult task, taking into account the sheer number of users.
Is there any other way to achieve the desired result? Maybe by making groups or roles? Or maybe tampering with Cognos repository?
Thank you for your time.
Stefan

If you want the first report to start automaticly you can create a new portal tab with one cognos viewer added to it. In the Cognos viewer select the start report at "entry" and choose "run the report". 
Add all users who need this report to a group and give acces to the new portal tab to this group. Make sure that the parameter "hideInaccessibleTabs" in de system.xml is set to true so that those users who shouldn't have access to the new tab don't see it. Btw, when updating the system.xml be aware of issue 530291.0.
The new portal tab can be added to the default profile (for all new users) and can be added to existing user profiles with a SDK script (search cognos knowledgebase with id 1021198).
