I don't know, the problem I have is I can't use any software/hardware 
that use group authentication. Perhaps setting on some debug... but I 
don't know how can I do it.

Ok I'll try.

yes of course:

if you need all smb.conf I can send you...

I have to reopen a new bug in glibc or do you think you can forward it 
to glibc BTS?

Thank you very much Steve, indeed!

Have a great day
