[Samba] 2 questions: Linux filesystems that truly compare to NTFS / winbind causes Linux to lockup when connectivity to AD is lost

Thank you for the info Jeremy

I think I will try EXT4 and see if I have better results then - also I 
agree with you about streams - I just think some of my more foolish 
clients wont.
Better just tell them "NO" firmly and then give them the example you 
gave - ;-)

Any workaround for the winbind problem I have? This to me is a very 
serious problem and all I can think of for a solution is of making a 
script that would ping the DC and if the connection to the DC was gone, 
to kill winbind, then if the DC is back, start winbind back up.
IS this a good idea? It seems very very bad and hacky to me... I am 
hoping with all my fingers crossed that you have a better solution!

Again, thank you - and keep up the excellent work!
