title: How to set autogroup in openLDAP
body: <p>I try setting autogroup in openLDAP. I added module</p>
  
  <pre><code>ldapsearch -LLL -o ldif-wrap=no -QY EXTERNAL -H ldapi:/// -b cn=module{0},cn=config
  dn: cn=module{0},cn=config
  objectClass: olcModuleList
  cn: module{0}
  olcModulePath: /usr/lib/ldap
  olcModuleLoad: {0}back_mdb
  olcModuleLoad: {1}memberof.la
  olcModuleLoad: {2}refint.la
  olcModuleLoad: {3}autogroup.la
  </code></pre>
  
  <p>added overlay:</p>
  
  <pre><code>dn: olcOverlay={2}autogroup,olcDatabase={1}mdb,cn=config
  objectClass: olcOverlayConfig
  objectClass: olcAutomaticGroups
  olcOverlay: {2}autogroup
  olcAGattrSet: {0}groupOfURLs memberURL member
  </code></pre>
  
  <p>I created group:</p>
  
  <pre><code>dn: cn=wusers,ou=wiki,ou=Services,ou=Groups,dc=domain,dc=com
  objectClass: top
  objectclass: groupOfURLs
  cn: wusers
  memberURL: ldap:///ou=People,dc=domain,dc=com??one?(&amp;(objectClass=inetOrgPerson)(!(memberof=cn=groupname,ou=Groups,dc=domain,dc=com)))
  </code></pre>
  
  <p>But I do requesting group then it empty. </p>
  
  <p>I see <a href="http://stackoverflow.com/questions/24762149/openldap-dynamic-groups-not-searching-by-member">a similar problem</a>, but did not help. </p>
  
  <p>I testing on Debian 9 slapd version 2.4.44.</p>
