pam_dial_auth(5)pam_dial_auth(5)NAMEpam_dial_auth - authentication management PAM module for dialups
SYNOPSIS
/usr/lib/security/pam_dial_auth.so
DESCRIPTION
The dialup PAM module, /usr/lib/security/pam_dial_auth.so, authenti‐
cates 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/secu‐
rity/pam_dial_auth.so is designed to be stacked immediately below the
/usr/lib/security/pam_unix.so 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 pass‐
words match, the user is authenticated. The following option may be
passed in to this service module:
debug syslog(3) debugging information at LOG_DEBUG
