Have you run the runcronjob after the admin approval ? Look here for more details : http://ez.no/doc/ez_publish/technical_manual/4_0/features/cronjobs/the_cronjob_scripts#workflow.
Yes I clear "all caches".
The user is in the database, in the 'ezuser' table. But not in users account.
Where do you think users can be stored ?
Which kind of problem do I meet ? Thank you for your help.
