can't login with login/pass, after signing up/logging with openid

hi, first i came to the site unregistered and logged with openid tonky.name

then i wanted to use usual login/password to checkout wiki.

didn't know password.

so i unsuccessfully tried to change password - didn't know the old one. i used 'remind password', and got login 'TonKy' and pass to my email.

but i can't login with them, nor change password to something else, after logging with openid.

openid still works, but i want login/password to work too. help!
