.SH NAME
pam_smb_passwd \- SMB password management module
.SH SYNOPSIS
.LP
.nf
\fBpam_smb_passwd.so.1\fR
.fi

.SH DESCRIPTION
.sp
.LP
The \fBpam_smb_passwd\fR module enhances the PAM password management stack.
This functionality supports the changing or adding of SMB passwords for local
Solaris users. The Solaris CIFS server uses SMB passwords to authenticate
connected Solaris users. This module includes the \fBpam_sm_chauthtok\fR(3PAM)
function.
.sp
.LP
The \fBpam_sm_chauthtok()\fR function accepts the following flags:
.sp

.RE

.sp
.ne 2
.na

Updates or creates a new \fBCIFS\fR local \fBLM\fR/\fBNTLM\fR hash for the user
that is specified in \fBPAM_USER\fR by using the authentication information
found in \fBPAM_AUTHTOK\fR. The \fBLM\fR hash is only created if the
\fBsmbd/lmauth_level\fR property value of the \fBsmb/server\fR service is set
to 3 or less. \fBPAM_IGNORE\fR is returned if the user is not in the local
\fB/etc/passwd\fR repository.

The interfaces in \fBlibpam\fR(3LIB) are MT-Safe \fBonly\fR if each thread
within the multi-threaded application uses its own PAM handle.

.LP
The \fBpam_smb_passwd.so.1\fR module should be stacked following all password
qualification modules in the \fBPAM\fR password stack.
