md2 is required for the python-ldap module. Using the python-ldap module is currently the only supported way to run ldap within Salt.

@dwoz I don't mean to cause notification spam but this is a serious issue for Enterprise environments. Salt is not using a pure python ldap implementation (I think a switch should be done, but that's a large overhaul) and this is preventing python-ldap from installing.

@Sxderp I will prioritize this.
