If I remember correctly, either '*' or '!!' prevents login.

Need some more clarity of problem...

if possible share the passwd file

Two exclamation points in the password field of /etc/shadow mean the account is locked. When you create a new account using the useradd command, a double exclamation mark is placed into the shadow file, until the system administrator assigns a password using the passwd command. In other words, the account exists but the user cannot log in.

Detailed explanation of the user creation process and the involved steps can be found in the RedHat System Administration Guide, here.
