            Greetings,

                 chklogin,(or  check login) is simple command line util-
            ity to examine if the given user credentials  are  valid  or
            not.  One  can invoke chklogin as shown below, with required
            arguments. chklogin uses the Linux-PAM module for  authenti-
            cating the supplied user information.

                 Usage: chklogin [-[b|h|v]] [-u username] [-p password]

            if  username is omitted, the credentials are checked against
            the user who has invoked chklogin; if password  is  omitted,
            chklogin  prompts  user  for  the  password string. Then, if
            given username and password is valid, chklogin asserts  this
            by   saying   ’authentication   successful’  otherwise  says
            ’authentication failed’.   In  boolean  mode(enabled  by  -b
            switch), chklogin displays 1 if authentication is successful
            and 0 otherwise.

            Installation

                 Installing chklogin is quite simple, go to  the  direc-
            tory  containing source of chklogin and issue following com-
            mand  as root
