when DN is empty).

.TP
.B argsfile <filename>
The ( absolute ) name of a file that will hold the

server's command line options
if started without the debugging command line option.
+.TP
+.B attributeoptions [option-name]...
+Define tagging attribute options or option tag/range prefixes.
+Options must not end with `-', prefixes must end with `-'.
+The `lang-' prefix is predefined.
+If you use the
+.B attributeoptions
+directive, `lang-' will no longer be defined and you must specify it
+explicitly if you want it defined.
+
+An attribute description with a tagging option is a subtype of that
+attribute description without the option.
+Except for that, options defined this way have no special semantics.
+Prefixes defined this way work like the `lang-' options:
+They define a prefix for tagging options starting with the prefix.
+That is, if you define the prefix `x-foo-', you can use the option
+`x-foo-bar'.
+Furthermore, in a search or compare, a prefix or range name (with
+a trailing `-') matches all options starting with that name, as well
+as the option with the range name sans the trailing `-'.
+That is, `x-foo-bar-' matches `x-foo-bar' and `x-foo-bar-baz'.
+
+RFC2251 reserves options beginning with `x-' for private experiments.
+Other options should be registered with IANA, see RFC3383 section 3.4.
+OpenLDAP also has the `binary' option built in, but this is a transfer
+option, not a tagging option.

+They are documented in the
.BR slapd-<backend> (5)
manual pages.
+.TP
+.B bdb
+This is the recommended backend for a normal slapd database.
+However, it takes more care than with the LDBM backend to configure
+it properly.
+It uses the Sleepycat Berkeley DB (BDB) package to store data.
+.TP
+.B ldbm
+This is the database backend which is easiest to configure.
+However, it does not offer the data durability features of the BDB
+backend.
+It uses Berkeley DB or GDBM to store data.
+.TP
+.B dnssrv
+This backend is experimental.
+It serves up referrals based upon SRV resource records held in the
+Domain Name System.
+.TP
+.B ldap
+This backend acts as a proxy to forward incoming requests to another
+LDAP server.
+.TP
+.B meta
+This backend performs basic LDAP proxying with respect to a set of
+remote LDAP servers.
+It is an enhancement of the ldap backend.
+.TP
+.B monitor
+This backend provides information about the running status of the slapd
+daemon.
+.TP
+.B null
+Operations in this backend succeed but do nothing.
+.TP
+.B passwd
+This backend is provided for demonstration purposes only.
+It serves up user account information from the system
+.BR passwd (5)
+file.
+.TP
+.B perl
+This backend embeds a
+.BR perl (1)
+interpreter into slapd.
+It runs Perl subroutines to implement LDAP operations.
+.TP
+.B shell
+This backend executes external programs to implement LDAP operations.
+It is is primarily intended to be used in prototypes.
+.TP
+.B sql
+This backend is experimental.
+It services LDAP requests from an SQL database.
+.TP
+.B tcl
+This backend is experimental.
+It embeds a
+.BR Tcl (3tcl)
+interpreter into slapd.
+It runs Tcl commands to implement LDAP operations.
