Most of the configuration of the ldap server has to do with getting correct
access controls to keep the data safe. Here is a sample:
-# Turn on automatic last modification time
-lastmod on
-# Index some things
-index uid eq
-index keyfingerprint eq
-index cn,sn approx,sub,eq
+# only allow plain text auth when we do crypto
+security simple_bind=128
-# Administrate
-#rootdn "uid=admin,ou=users,dc=debian,dc=org"
-#rootpw
+# and the database definition
+include /etc/ldap/userdir-ldap-slapd.conf
-# Restrict reading/modification of the password to administration and self
-access to attrs=userpassword,sshrsaauthkey
- by self write
- by dn="uid=admin,ou=users,dc=debian,dc=org" write
- by group="uid=admin,ou=users,dc=debian,dc=org" write
- by * compare
+# Overlays are useful to enforce constraints:
-access to attrs=emailforward
- by dn="uid=admin,ou=users,dc=debian,dc=org" write
- by group="uid=admin,ou=users,dc=debian,dc=org" write
- by self write
- by addr=127.0.0.1 read
- by domain=.*\.debian\.org read
- by * none
-access to attrs=c,l,loginShell,ircNick,labeledURL
- by dn="uid=admin,ou=users,dc=debian,dc=org" write
- by group="uid=admin,ou=users,dc=debian,dc=org" write
- by self write
-access to attrs=facsimileTelephoneNumber,telephoneNumber,postalAddress,postalC
-ode,loginShell,onvacation,privateSub,latitude,longitude
- by dn="uid=admin,ou=users,dc=debian,dc=org" write
- by group="uid=admin,ou=users,dc=debian,dc=org" write
- by self write
- by dn="uid=.*,ou=users,dc=debian,dc=org" read
- by * none
-access to *

+Note that in more modern versions of slapd, the "by addr" and "by domain"
+syntax has changed and the following should be used instead:
+ by peername.ip=127.0.0.1 read
+ by domain.subtree=debian.org read
+
+

Here is the initial seed file to import and setup the proper entries:
dn: dc=org
