Full_Name: Emmanuel L.charny Version: 2.4.44 OS: Linux CentOS 6 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (176.154.3.51) Start an OpenLDAP server using the dynamic configuration (slapd.d) from a slapd.conf file that does not contain a synprov module : $ /opt/symas/bin/slaptest -f /opt/symas/etc/openldap/slapd.conf -F /opt/symas/etc/openldap/slapd.d $ /etc/init.d/solserver start -d 256 $ grep -ri "olcSpNoPresent" slapd.d $ ... Then inject the syncprov module in the server : dn: cn=module{0},cn=config changetype: modify add: olcModuleLoad olcModuleLoad: syncprov.la - The olcSpNoPresent attribute is not present : $ grep -ri "olcSpNoPresent" slapd.d $ ... You can stop and restart the server, the attribute is still not present. Going back to the slapd.conf file, add the module : ... # Uncomment the mululeloads as needed to enable additional # functionalityi when configured. NOTE: We package many # more modules options than those found below. moduleload back_mdb.la moduleload back_monitor.la moduleload syncprov.la # Added module ... and regenerate the slapd.d content : $ /etc/init.d/solserver stop $ rm -rf /opt/symas/etc/openldap/slapd.d/* $ /opt/symas/bin/slaptest -f /opt/symas/etc/openldap/slapd.conf -F /opt/symas/etc/openldap/slapd.d $ grep -ri "olcSpNoPresent" /opt/symas/etc/openldap/slapd.d slapd.d/cn=config/cn=schema.ldif:olcAttributeTypes: ( OLcfgOvAt:1.3 NAME 'olcSpNoPresent' DESC 'Omit Present slapd.d/cn=config/cn=schema.ldif: $ olcSpSessionlog $ olcSpNoPresent $ olcSpReloadHint ) ) $... This is problematic...
