Check password age
Hi Guys,
I hope one of you has already done this and is kind enough to share your script with me.
I have a Solaris8 server that uses password aging for its local user accounts. I need a script that checks the age of the password and then sends the user an email if the password is about to expire. It needs to send an email when the password will expire in 10 days then it needs to send a second email when there is 5 days left before it expires. It also needs to send an email to an admin account if a password has already expired, including the root password.
Thanks...

Hi there,
There's something I don't understand. The same string does not give the same md5 hash everytime. I wanted to find a way to check someone's password but the following script obviously shows that it's not possible that way :

Hi All,
I got a definition on /etc/login.defs
PASS_MAX_DAYS 41
and on /etc/shadow, most of the user id fifth column (max age) is 40.
Is that different policy or not? If it is the same policy, then the above policy don't match, right.
Thanks for any comment you may add.
Cheers,... (2 Replies)

shadow
SHADOW(5) File Formats Manual SHADOW(5)
NAME
shadow - encrypted password file
DESCRIPTION
shadow contains the encrypted password information for user's accounts and optional the password aging information. Included is
Login name
Encrypted password
Days since Jan 1, 1970 that password was last changed
Days before password may be changed
Days after which password must be changed
Days before password is to expire that user is warned
Days after password expires that account is disabled
Days since Jan 1, 1970 that account is disabled
A reserved field
The password field must be filled. The encryped password consists of 13 to 24 characters from the 64 character alphabet a thru z, A thru
Z, 0 thru 9, . and /. Refer to crypt(3) for details on how this string is interpreted.
The date of the last password change is given as the number of days since Jan 1, 1970. The password may not be changed again until the
proper number of days have passed, and must be changed after the maximum number of days. If the minimum number of days required is greater
than the maximum number of day allowed, this password may not be changed by the user.
An account is considered to be inactive and is disabled if the password is not changed within the specified number of days after the pass-
word expires. An account will also be disabled on the specified day regardless of other password expiration information.
This information supercedes any password or password age information present in /etc/passwd.
This file must not be readable by regular users if password security is to be maintained.
FILES
/etc/passwd - user account information
/etc/shadow - encrypted user passwords
