The signature of ldap2.get_entry() changed so normalize wasn't being
handled properly so the basedn was always being appended causing our
entry in cn=config to be not found.
ticket 414
Neither of these was working properly, I assume due to changes in the ldap
backend. The normalizer now appends the basedn if it isn't included and
this was causing havoc with these utilities.
After fixing the basics I found a few corner cases that I also addressed:
- you can't/shouldn't disable compat if the nis plugin is enabled
- we always want to load the nis LDAP update so we get the netgroup config
- LDAPupdate.update() returns True/False, not an integer
I took some time and fixed up some things pylint complained about too.
