NAME
pam_unix_auth − PAM authentication module for UNIX
SYNOPSIS
pam_unix_auth.so.1
DESCRIPTION
The pam_unix_auth module implements pam_sm_authenticate(), which provides functionality to the PAM authentication stack. It provides functions to verify that the password contained in the PAM item PAM_AUTHTOK is the correct password for the user specified in the item PAM_USER. If PAM_REPOSITORY is specified then user’s passwd is fetched from that repository. Otherwise the default nsswitch.conf(4) repository is searched for that user.
RETURN VALUES
The following
values are returned:
PAM_AUTH_ERR
Authentication failure
PAM_BUF_ERR
Memory buffer error
PAM_PERM_DENIED
Permission denied
PAM_SYSTEM_ERR
System error
PAM_SUCCESS
Successfully obtains authentication token
PAM_USER_UNKNOWN
No account present for user

NOTES
The interfaces in libpam(3LIB) are MT-Safe only if each thread within the multi-threaded application uses its own PAM handle.
The pam_unix(5) module might not be supported in a future release. Similar functionality is provided by pam_authtok_check(5), pam_authtok_get(5), pam_authtok_store(5), pam_dhkeys(5), pam_passwd_auth(5), pam_unix_account(5), pam_unix_auth(5), and pam_unix_session(5).
