Finally I get the problem. The interface have two field i.e. primary field to provide password and then the second field to enter password again.
The UI is bad for this as the font color is white and it blends with backgorund. It does not appear that second field even exist.
If you zoom into key field in picture I have attached, you will find they are two input fields but just by looking at it you can not make out.
DT you guys need to fix this UI issue. I spent 2 hours searching and later found out this stupid issue.
Now, this is working for me but now I have landed into another issue (Icloud Sync problem on iPad).
