Add new user menu has no password field


When I try to add a new user as a admin of a subsite/blog a get no password field so i cant set a password for the new user.

Then if I add a new user without setting the password the user gets one mail saying "activate you account"

When the acitvation link is pressed I get another mail saying

You can log in with the following information:
Username: hubertus3
Password: [User Set]

The password i User Set.

The problem is where do I set the password if I don have the password to login.
