NAME

pam_dial_auth - authentication management PAM module for dialups

SYNOPSIS

/usr/lib/security/pam_dial_auth.so.1

DESCRIPTION

The dialup PAM module, /usr/lib/security/pam_dial_auth.so.1, authenticates a user according to the /etc/dialups and /etc/d_passwd files. Only pam_sm_authenticate( ) is implemented within this module. pam_sm_setcred( ) is a null function. /usr/lib/security/pam_dial_auth.so.1 is designed to be stacked immediately below the /usr/lib/security/pam_unix.so.1 module for the login service.

pam_sm_authenticate( ) performs authentication only if both the /etc/dialups and /etc/d_passwd files exist. The user's terminal line is checked against entries in the /etc/dialups file. If there is a match, the user's shell is compared against entries in the /etc/d_passwd file. If there is a matching entry, the user is prompted for a password which is validated against the entry in the /etc/d_passwd file. If the passwords match, the user is authenticated. The following option may be passed in to this service module:

debug

syslog(3) debugging information at LOG_DEBUG level.
