Setup

Install lbdb and libnet-ldap-perl:

aptitude install lbdb libnet-ldap-perl

Once you’ve done that, copy the lbdb configuration files into your home directory:

mkdir .lbdb
cp /etc/lbdb.rc .lbdb/rc
cp /etc/lbdb_ldap.rc .lbdb/ldap.rc

Add your LDAP server to the .lbdb/ldap.rc, e.g.:

%ldap_server_db = (
  'christianschenk' => ['localhost',
            'cn=users,dc=christianschenk,dc=org',
            'givenname sn cn mail', 'givenname cn sn mail o',
            '${mail}', '${givenname} ${sn}', '${o}' ]
);

Then add m_ldap to the line saying METHODS in .lbdb/rc and enable your LDAP server by adding it to the LDAP_NICKS like so:

LDAP_NICKS="christianschenk"

You can test your setup with the lbdbq command: simply call it with a string you’re searching for. Once it works for you like expected, add this line to your .muttrc:

set query_command="lbdbq '%s'"

Mutt will use this to send queries to lbdb.

Usage

If Mutt asks you for the email address simply enter some string and hit CTRL+t or TAB: this will auto-complete the address for you. That’s it.
