THE Idmap patch :-)

includes a --with-idmap=no switch to disable idmap usage if you find
problems.

cosmetic fixes and param aliases to separate winbind from idamp roles.

A temporarily remote idmap winbind compatibility backend.
As I have time I will further change code to not call directly winbind
(partly done but not tested) and a specilized module will be built in place
for the current glue hack.

The patch has been tested locally in my limited time, the patch is simple and
clear and should not reserve problems, if any just disable it.

As usual, comments and fisex are welcome :-)

Simo.
