i noticed that root@master:~# /usr/share/univention-ldap/ldap_setup_index --add-eq memberOf
was adding some permanent stuff
after restarting slapd and doing erata updates, the memberOf is back again in /etc/slapd.conf and slapd is not starting because of that Attribute
so i removed it again
root@master:~# service slapd stop
root@master:~# /usr/share/univention-ldap/ldap_setup_index --rm-eq memberOf
root@master:~# service slapd start
I would be still interested in how to handle the index in this case related to “memberOf”
