We should delete all information inside session and session_attribute
tables. We don't have any trac.htdigest file. Maybe 'cause we're storing
pwd in the trac database (SessionStore) [1].

The ideal would be to delete users through the trac-admin utility:

   - List users: trac-admin /project session list

I can find here the same users that we find in the session table.


   - Delete users: trac-admin /project session delete <username1> ...
   <usernameN>

    But doing this for ~90.000 users is not viable.

4. deletion of the users via manage user accounts results in removal
