No change? Which tests are failed?
AFAIK, the following tests would be passed w/ the fix.

    Test v6LC.3.1.2: Receiving DAD Neighbor Solicitations and Advertisements
    åà€#3 Part B: NUT receives DAD NS (target == NUT)
    åà€#5 Part D: NUT receives DAD NA (target == NUT)

    Test v6LC.3.1.3: Validation of DAD Neighbor Solicitations
    åà€#14 Part I: NUT receives valid DAD NS (Reserved Field)
    åà€#15 Part J: NUT receives valid DAD NS (contains TLL)

    Test v6LC.3.1.4: Validation of DAD Neighbor Advertisements
åà€    #23 Part H: NUT receives valid DAD NA (Reserved Field)
åà€    #24 Part I: NUT receives valid DAD NA (contains SLL)

If these tests are still failed, it might be a timing problem.
Setting this variable via rc.local sounds sightly later than expected.
The result might change by using sysctl.conf instead, like this;
  net.ipv6.conf.default.accept_dad=2
