[TYPO3-dev] Create and login temp user

[Sebastian Gebhard]

Hi list,

i'm currently working on an extension that can be used both by guests 
and logged in FE users. The extension has to store some data while it is 
used and associate the data with the user.
Of course the ragarding table has a field user_id which points to 
fe_users table.
Now for guests I thought about creating a temporary fe_users record and 
log the user in silently.

How can I do that login? I took a look at tslib_feuserauth but none of 
the methods seems to fit my requirements. Would you give me a hint please?

Thanks and regards,
Sebastian
