ezmlm with dash-trick patch

[HF Kwan]

If I want to use the qmail-ldap(patched with 20010301) with ezmlm, 
which patch dash-trick should be the best among the following 
3 patches?

  20010301
  20010305
  20010306

It seems that 20010301 should be workable with the 
ldap patch 20010301, but how about the 20010305 and 20010306?
What is the difference among 0301,0305 and 0306?
