r23085: Activate the winbindd validation code in 3_0_26, too.

Original comment of the 3_0 checkin (r23040):

Activate the winbindd cache validation code in the                                    
winbindd main function.                                                               
                                                                                      
I have tested and somewhat extended the code, and it seems                            
to do a good job. I have possibly not caught all error                                
conditions though.
