Hi people...

i have this same problem in a FreeBSD 9.0 with samba rc3 and git version

Andrew, this patch work only in git version ?

other issue...

i can use the sysvol path in other place ? for example:

[sysvol]
   path = /samba/sysvol
   read only = No

obvious... with netlogon path correct too.

thanks
