Re: [Samba] How to get password expiration?




On my ubuntu machines I added

auth    required        pam_exec.so /scripts/password_expire.sh

to the beginning of /etc/pam.d/common-auth

it looks pretty similar to what I did below.
In the /etc/bash.bashrc
I added a check to wait for the file to be less than 1 second old before
looking at it.
break out after 5 seconds in case something failed or is taking longer then
it should.

now people get how many days till their password expires. Thank you all so
much :-)
