.SH "DESCRIPTION"
.PP
The
\fBpam_acct_mgmt\fR
function is used to determine if the users account is valid\&. It checks for authentication token and account expiration and verifies access restrictions\&. It is typically called after the user has been authenticated\&.
.PP
The
\fIpamh\fR
argument is an authentication handle obtained by a prior call to pam_start()\&. The flags argument is the binary or of zero or more of the following values:
.PP
PAM_SILENT
.RS 4
Do not emit any messages\&.
.RE
.PP
PAM_DISALLOW_NULL_AUTHTOK
.RS 4
The PAM module service should return PAM_NEW_AUTHTOK_REQD if the user has a null authentication token\&.
.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 account is valid but their authentication token is
\fIexpired\fR\&. The correct response to this return\-value is to require that the user satisfies the
\fBpam_chauthtok()\fR
function before obtaining service\&. It may not be possible for some applications to do this\&. In such cases, the user should be denied access until such time as they can update their password\&.
.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
User unknown to password service\&.
