hi,
No need to. Did you also make users.auth.php? If you didn't, try to read the link i gave you.
The steps you have to follow:
* Enable ACL (in config)
* Choose the way your users will be controlled (most fo the time plain)
* Choose your nickname and set it as superuser
* Make the files (users.auth.php en check for acl.auth.php)
* Make a user manually (your variables; you can read this in
http://wiki.splitbrain.org/wiki:auth:plain)
* Finetune your installation
These are the rough steps you have to take. If it still doesn't work, just come to our IRC-channel: #dokuwiki :-D
