Guys, I'm so sorry for wasting your time.

I've just dropped all kamailio mysql users, database and commented kamailioro user in kamctlrc config file and than ran a kamdbctl create command again, to refurbish all the structure.

So that, it didn't create kamailioro user, like it was in previous time.
And now it doesn't requesting the kamailioro user credentials at all.
Works fine, daemon starts without problem.

Thanks for reply!
Question is now closed for me.
