Clarification on /etc/passwd file entry


I am working on a UNIX AIX system and all the entries in /etc/passwd file are in the following format..


I have an idea abt each field, but I am confused abt the values in the second field.

If the value of the second filed is 'x' then it means the password is stored in /etc/shadow file.

* means you cant login using this id in unix login prompt

but what does the value '!' means?

and I checked, there is no /etc/shadow file in the system, so where the password is stored.

From the AIX documentation:
If a user ID has a password, then the password field will have an ! (exclamation point). If the user ID does not have a password, then the password field will have an * (asterisk). The encrypted passwords are stored in the /etc/security/passwd file.
