NAME
       pam_debug - PAM module to debug the PAM stack
SYNOPSIS
       pam_debug.so [auth=value] [cred=value] [acct=value]
                    [prechauthtok=value] [chauthtok=value] [auth=value]

       determining how the PAM stack is operating. This module returns what
       its module arguments tell it to return.

       acct=value
           The pam_sm_acct_mgmt(3) function will return value.
       prechauthtok=value
           The pam_sm_chauthtok(3) function will return value if the
           PAM_PRELIM_CHECK flag is set.
       chauthtok=value
           The pam_sm_chauthtok(3) function will return value if the
           PAM_PRELIM_CHECK flag is not set.
