wip ... cleanups for pull request
fully working/tested code - many improvements and fixups:
1) servers in config can now be tab, space, comma or semi-colon separated
2) default userkey for authorization has been changed to take advantage of Stripped-User-Name if present
3) the module no longer attempts to create the Stripped-User-Name and Stripped-Domain attributes and instead relies on policy
4) example configuration and readme have been updated to reflect the changes
