commit c21515b1577d5e71fddc20b91bae7abfda6c90e1

    Branch: master
    Fix Description: Changed the ldbm_config for idlistscanlimit to allow running
    change.  Added a new attribute nsIDListScanLimit that works just like
    nsLookThroughLimit for user entries.  For each search operation, calculate
    the idlistscanlimit to use based on any nsIDListScanLimit or database config.
    The biggest change was to extend the internal database API to allow the
    idlistscanlimit (aka allidslimit) to be passed down into the lowest level of
    the code where it is used.
    Platforms tested: RHEL6 x86_64
    Flag Day: no
    Doc impact: Yes - will need to document how nsIDListScanLimit and
    nsslapd-idlistscanlimit work now

nsslapd-requiresrestart: cn=config,cn=ldbm:nsslapd-idlistscanlimit
nsslapd-idlistscanlimit: 300


I could successfully run ldapmodify against idlistscanlimit per user and global config attributes. Hence marking the bug as verified.
