Hi,

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

root:!:0:0::/:/usr/bin/ksh

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.
