13 pam_authtok_store provides functionality to the PAM password management
14 stack. It provides one function: pam_sm_chauthtok().
15
16
17 When invoked with flags set to PAM_UPDATE_AUTHTOK, this module updates
18 the authentication token for the user specified by PAM_USER.
19
20
21 The authentication token PAM_OLDAUTHTOK can be used to authenticate the
22 user against repositories that need updating (NIS, LDAP). After suc‐
23 cessful updates, the new authentication token stored in PAM_AUTHTOK is
24 the user's valid password.
25
26
27 This module honors the PAM_REPOSITORY item, which, if set, specifies
28 which repository is to be updated. If PAM_REPOSITORY is unset, it fol‐
29 lows the nsswitch.conf(4).
30
31
32 The following option can be passed to the module:
33
34 debug syslog(3C) debugging information at the LOG_DEBUG
35 level
36
37
38 server_policy If the account authority for the user, as specified by
39 PAM_USER, is a server, do not encrypt the authentica‐
40 tion token before updating.
41
42
44 PAM_SUCCESS Successfully obtains authentication token
45
46
47 PAM_SYSTEM_ERR Fails to get username, service name, old password or
48 new password, user name null or empty, or password
49 null.

77 The pam_unix(5) module is no longer supported. Similar functionality is
78 provided by pam_authtok_check(5), pam_authtok_get(5), pam_auth‐

83 If the PAM_REPOSITORY item_type is set and a service module does not
84 recognize the type, the service module does not process any informa‐
85 tion, and returns PAM_IGNORE. If the PAM_REPOSITORY item_type is not
86 set, a service module performs its default action.
