| pam_passwd_auth - authentication module for password |
SYNOPSIS
|
pam_passwd_auth provides authentication functionality to the password service as implemented by passwd(1). It differs from the standard PAM authentication modules in its prompting behavior.
The name of the user whose password attributes are to be updated must be present in the PAM_USER item. This can be accomplished due to a previous call to pam_start(3PAM), or explicitly set by pam_set_item(3PAM). Based on the current user-id and the repository that is to by updated,
the module determines whether a password is necessary for a successful update of the password repository, and if so, which password is required.
The following option can be passed to the module:
- debug
-
syslog(3C) debugging information at the LOG_DEBUG level
- nowarn
- Turn off warning messages
|
|
The following values are returned:
- PAM_SUCCESS
- Successfully obtains authentication token
- PAM_SYSTEM_ERR
- System error
- PAM_BUF_ERR
- Memory buffer error
