The comanay wants the user to be deleted with in a week of the user leaving the organization.

For example I have a user named test1 with id 202 - now he has left the organization and I have deleted the id 202.How can I make sure that after a month nobody else creates another user with an Id 202.This is my actual question.
I don't know of another way. You could create a dummy user to hold the UID in the /etc/passwd file but why not just leave the user in there in a disabled state. This works everywhere else. AIX will reuse that UID if it doesn't find it in the /etc/passwd file.

Name
       shexp - display password expiration information for a user

Syntax
       shexp [-q] [username]

Description
       The command is used to display a user's password expiration information.  The specified username, or logname if no username is supplied, is
       converted to a UID by searching through the passwd file.  The UID is then used to look up the user's entry in  the  Auth  Data  Base.   The
       password expiration information is then printed out in format.
       % shexp
       Expires Tue Dec	6 10:49:18 EST 1988
       If  the	password  has  already expired the word Expires will be replaced with the word Expired. If password expiration is disabled for the
       particular user in question the output of will be Never expires.

Options
       -q   Instead of displaying the expiration date and time in format, outputs it as three decimal numbers: the minimum password lifetime,  the
	    maximum password lifetime, and the password modification time.  All three numbers are displayed as they are found in the database.

Restrictions
       Only the super-user may obtain information about users with UIDs other than the real UID of the invoking process.

Diagnostics
       User not found in passwd data base.
       There is no entry in for the specified username.

       Cannot stat auth file.
       The database is missing (security features may not be enabled).

       Insufficient privilege.
       An insufficiently privileged user is asking for information about a username with a UID different then their current real-UID.

       An exit value of 0 indicates a successful operation, any other exit status indicates an error.
