unix_chkpwd – Helper binary that verifies the password of the current user
 

Synopsis



unix_chkpwd [...]


 

DESCRIPTION


unix_chkpwd

is a helper program for the
pam_unix
module that verifies the password of the current user. It also checks password and account expiration dates in
shadow. It is not intended to be run directly from the command line and logs a security violation if done so.

It is typically installed setuid root or setgid shadow.

The interface of the helper – command line options, and input/output data format are internal to the
pam_unix
module and it should not be called directly from applications.
