.SH "DESCRIPTION"
.PP
The
\fBpam_sm_acct_mgmt\fR
function is the service module\*(Aqs implementation of the
\fBpam_acct_mgmt\fR(3)
interface\&.
.PP
This function performs the task of establishing whether the user is permitted to gain access at this time\&. It should be understood that the user has previously been validated by an authentication module\&. This function checks for other things\&. Such things might be: the time of day or the date, the terminal line, remote hostname, etc\&. This function may also determine things like the expiration on passwords, and respond that the user change it before continuing\&.
.PP
Valid flags, which may be logically OR\*(Aqd with
\fIPAM_SILENT\fR, are:
.PP
PAM_SILENT
.RS 4
Do not emit any messages\&.
.RE
.PP
PAM_DISALLOW_NULL_AUTHTOK
.RS 4
Return
\fBPAM_AUTH_ERR\fR
if the database of authentication tokens for this authentication mechanism has a
\fINULL\fR
entry for the user\&.
.RE
.SH "RETURN VALUES"
.PP
PAM_ACCT_EXPIRED
.RS 4
User account has expired\&.
.RE
.PP
PAM_AUTH_ERR
.RS 4
Authentication failure\&.
.RE
.PP
PAM_NEW_AUTHTOK_REQD
.RS 4
The user\*(Aqs authentication token has expired\&. Before calling this function again the application will arrange for a new one to be given\&. This will likely result in a call to
\fBpam_sm_chauthtok()\fR\&.
.RE
.PP
PAM_PERM_DENIED
.RS 4
Permission denied\&.
.RE
.PP
PAM_SUCCESS
.RS 4
The authentication token was successfully updated\&.
.RE
.PP
PAM_USER_UNKNOWN
.RS 4
