Name

pam_authtok_store– password management module

Synopsis

pam_authtok_store.so.1

Description

pam_authtok_store provides functionality to the PAM password management stack. It provides one function: pam_sm_chauthtok().

When invoked with flags set to PAM_UPDATE_AUTHTOK, this module updates the authentication token for the user specified by PAM_USER.

The authentication token PAM_OLDAUTHTOK can be used to authenticate the user against repositories that need updating (NIS, LDAP). After successful updates, the new authentication token stored in PAM_AUTHTOK is the user's valid password.

This module honors the PAM_REPOSITORY item, which, if set, specifies which repository is to be updated. If PAM_REPOSITORY is unset, it follows the nsswitch.conf(4).

The following option can be passed to the module:

debug

syslog(3C) debugging information at the LOG_DEBUG level

server_policy

If the account authority for the user, as specified by PAM_USER, is a server, do not encrypt the authentication token before updating.

Errors

PAM_SUCCESS

Successfully obtains authentication token

PAM_SYSTEM_ERR

Fails to get username, service name, old password or new password, user name null or empty, or password null.

Attributes

See attributes(5) for descriptions of the following attributes:

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 is no longer supported. 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).

If the PAM_REPOSITORY item_type is set and a service module does not recognize the type, the service module does not process any information, and returns PAM_IGNORE. If the PAM_REPOSITORY item_type is not set, a service module performs its default action.
