[Samba] smbd doesn't start anymore

Tue Sep 23 08:42:23 MDT 2014

Thanks for your answer Rowland but when I read again smb.conf man 
(https://www.samba.org/samba/docs/man/manpages-3/smb.conf.5.html#SOCKETOPTIONS) 
I don't see any line mentionning that socket options mustn't be used.....

I'm really sorry to have made some mistakes (i'm just a human ... me), 
schema instead of schema_mode is a typo and some options reverted to 
default are used for tuning (and not deleted .... sorry again)

Thanks again for your answer pointing some of my mistakes that have 
nothing to do with my problem.... but my smb.conf is clean now (i keep 
socket options for the moment).

Regards
Bruno
