Unknown db in slapd.conf

[espeake@oreillyauto.com]

I have a brand new Ubuntu-12.04 server with a brand new build of openldap
2.4.36 on it and I am try to set it up for MMR with mdb.  I get the
following error when I try slapadd my config.

524c62f1 line 61 (databse               mdb)
524c62f1 /usr/local/etc/openldap/slapd.conf: line 61: <database> failed
init (mdb)!

Now when I look at man slapd.conf and these are the database types that are
shown for use.  There is nothing there showing mdb, but I know that it is a
viable selection.

 database <databasetype>
              Mark the beginning of a new database instance definition.
<databasetype>  should  be  one  of  bdb,  config, dnssrv, hdb, ldap, ldif,
meta, monitor, null, passwd, perl, relay, shell, or sql, depending on which
backend will serve the database.

in my slapd.conf file I have the following setup (just partially listing
here):

# Load dynamic backend modules:
 modulepath     /usr/local/libexec/openldap
 moduleload     back_mdb.la
 moduleload     back_ldap.la

############################################################################
database        mdb

I have checked and double cheked to be sure
that /usr/local/libexec/openldap/back_mdb.la exists.

What simple thing am I missing?
