Configuration of APN on Build 6013 & 6100 has a bug and DOES NOT work.
It is very bad to see that bugs are not identified well before releasing of new builds by ManageEngine. 

Same bug existed in 6013 and now again in 6100. ManageEngine ticket number logged for this issue reported is  #4067007 

This is causing a huge hold up in configuring & using ADSSP to users of the company. 

There should be reward points or something offered by ManageEngine for such bugs reported by end-users. Cause apparently, there seems to be no Testers at ManageEngine
