|
|
.In security/pam_appl.h
|
|
.Ft "int"

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
function returns the cached authentication token,
|
|
or prompts the user if no token is currently cached.
|
|
Either way, a pointer to the authentication token is stored in the
|
|
location pointed to by the
|
|
.Fa authtok
|
|
argument.
|
|
.Pp
|
|
The
|
|
.Fa item
|
|
argument must have one of the following values:
|
|
.Bl -tag -width 18n
|
|
.It Dv PAM_AUTHTOK
|
|
Returns the current authentication token, or the new token
|
|
when changing authentication tokens.
|
|
.It Dv PAM_OLDAUTHTOK
|
|
Returns the previous authentication token when changing
|
|
authentication tokens.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Fa prompt
|
|
argument specifies a prompt to use if no token is cached.
|
|
If it is
|
|
.Dv NULL ,
|
|
the
|
|
.Dv PAM_AUTHTOK_PROMPT
|
|
or
|
|
.Dv PAM_OLDAUTHTOK_PROMPT
|
|
item,
|
|
as appropriate, will be used.
|
|
If that item is also
|
|
.Dv NULL ,
|
|
a hardcoded default prompt will be used.
|
|
.Pp
|
|
If
|
|
.Fa item
|
|
is set to
|
|
.Dv PAM_AUTHTOK
|
|
and there is a non-null
|
|
.Dv PAM_OLDAUTHTOK
|
|
item,
|
|
.Nm
|
|
will ask the user to confirm the new token by
|
|
retyping it.
|
|
If there is a mismatch,
|
|
.Nm
|
|
will return
|
|
.Dv PAM_TRY_AGAIN .
