[MonetDB-users] authorize! what's wrong?

Hi! I've installed monetdb from sources.

./MonetDB5-server-5.16.4.tar.bz2 ./MonetDB-client-1.34.4.tar.bz2 ./MonetDB-SQL-2.34.4.tar.bz2

merovingan started database test created

but mclient asks for password! and i don't know which one. Manual says that monetdb uses system authorization, but mclient answers:

korisk@pс64:~$ mclient -l sql -d test

user(korisk):

password:

InvalidCredentialsException:checkCredentials:invalid credentials for user 'korisk'

i use Ubuntu 9.10 x86_64

What's wrong?

Thank you.
