Remove administrator rights

Hello,

I've got the problem that I want to remove administrator rights from a user (the one, well, it's my own account, which I gave initial admin rights via the ejabberd.config). I've modified the configuration accordingly, gave admin-rights to anonther user and restarted ejabberd. Now the other (new) user can access admin functions (like I intended) but the one wich should be degraded to normal user is still able to access all admin functions.

Any suggestions or am I missing something? Searched the forums but found no answer...
