This relates to it being used in your slapd configuration. However, the man

That is not sufficient, you would at least need:
in the affected database. Additionally, note that the overlay only maintains
the memberof attribute for *changes* to the member (or attribute specified by
memberof-member-ad) attribute, the initial population is up to you (or, you
could probably send trivial modifications to all your groupOfNames entries to
force the overlay to update the attributes.

Firstly, you should be using memberof=DN, not memberof-dn=DN, secondly, does
your user have a matching attribute?

Please consult the nss_ldap documentation for nss_base_passwd, but, typically,
it should use the value you have supplied as a filter to a search operation.
Have you manually verified that the accounts you expect to be matched by your
filter do, in fact, match the filter? For example, by using:
$ ldapsearch -x -b ou=people,dc=ldn,dc=sw,dc=com "(memberof-
Note: I copied from your configuration, if your configuration is wrong, fix it,
and re-paste the filter, to make sure you are testing what you have configured
