Greetings,

I would like to present patch for replacing StandardError exception
with Exception class in ipapython/adminutil.py. Also replacing
BaseException class with Exception class. 

Though the use of StandardError is many places. I would like to start
with ipapython/adminutil.py

This is my first patch. Please let me know if my approach on this is 
correct.

Regards
Niranjan

Subject: [PATCH] Use Exception class instead of BaseException

1. Replace BaseException with Exception class.
2. Remove StandardError and use Exception class. StandError is deprecated 
(Python3)
3 .From python3.0 use of , is not recommended, instead
use "as" keyword (PEP 3110)
