logging into domain

I cannot log into domain. domain name is "mshome", i set up Samba domain server PDS, and i try to log in from Win xp but is when I put in mycomputer, domain name for xp - mshome, which is domain name, it automaticly asks for username and pass. i enter username and pass and it says - "The following errorr... account is not authorizet to log in from this station!" I have created account in smbpasswd, and using pdbedit also. it has machine name like "frano$", i tried using users that i have created but it wont let me. I tried to find an answer in "how to" for samba, an found something that in "ldap" are stored passwords and account for domain. anybody has any clue what to do?
