I am trying to implement memberof overlay on Ubuntu 10.04.4 LTS and

created the following ldif:

adding new entry "olcOverlay={2}memberof,olcDatabase={1}hdb,cn=config"
ldap_add: Other (e.g., implementation specific) error (80)
        additional info: member attribute="memberUid" must either
have DN (1.3.6.1.4.1.1466.115.121.1.12) or nameUID
(1.3.6.1.4.1.1466.115.121.1.34) syntax

overlay memberof only supports DN as membership attribute (as DN and
nameUID type). I don't know any workaround for your case.
