.SH DESCRIPTION
|
|
.LP
|
|
.B Slappasswd
|
|
is used to generate an userPassword value
|
|
suitable for use with
|
|
.BR ldapmodify (1)
|
|
or
|
|
.BR slapd.conf (5)
|
|
.I rootpw
|
|
configuration directive.
|
|
.SH OPTIONS
|
|
.TP
|
|
.B \-v
|
|
enable verbose mode.
|
|
.TP
|
|
.B \-u
|
|
Generate RFC2307 userPassword values (the default). Future
|
|
versions of this program may generate alternative syntaxes
|
|
by default. This option is provided for forward compatibility.
|
|
.TP
|
|
.BI \-s " secret"
|
|
The secret to hash. If not provided, the user will be prompted
|
|
for the secret to hash.
|
|
.TP
|
|
.BI \-h " scheme"
|
|
If -h is specified, one of the following RFC2307 schemes may
|
|
be specified:
|
|
.IR {CRYPT} ,
|
|
.IR {MD5} ,
|
|
.IR {SMD5} ,
|
|
.IR {SSHA} ", and"
|
|
.IR {SHA} .
|
|
The default is
|
|
.IR {SSHA} .
|
|
.TP
|
|
.BI \-c " crypt-salt-format"
|
|
Specify the format of the salt passed to
|
|
.BR crypt (3)
|
|
when generating {CRYPT} passwords.
|
|
This string needs to be in
|
|
.BR sprintf (3)
|
|
format and may include one (and only one) %s conversion.
|
|
This conversion will be substituted with a string random
|
|
characters from [A\-Za\-z0\-9./]. For example, "%.2s"
|
|
provides a two character salt and "$1$%.8s" tells some
|
|
versions of crypt(3) to use an MD5 algorithm and provides
|
|
8 random characters of salt. The default is "%s", which
|
|
provides 31 characters of salt.
|
|
.SH LIMITATIONS
|
|
The practice storing hashed passwords in userPassword violates
|
|
Standard Track (RFC2256) schema specifications and may hinder
|
|
interoperability. A new attribute type to hold hashed
|
|
passwords is needed.
|
|
.SH "SECURITY CONSIDERATIONS"
|
|
Use of hashed passwords does not protect passwords during
|
|
protocol transfer. TLS or other eavesdropping protections
|
|
should be inplace before using LDAP simple bind. The
|
|
hashed password values should be protected as if they
|
|
were clear text passwords.
