[Samba] Import idmap database error on classicupgrade process

[Elias Pereira]

You're right, man! Sorry! My mistake!

I put that file because I read in somewhere about the persistent and
temporary files regarding .tdb files. The winbindd_idamp.tbm was on that
list, and I think that's why I left it in the folder. :D

Another doubt. For the provisioning starts, I had to comment out the line
referring to the ldap backend in the smb.conf of samba3.

# passdb backend   = ldapsam:ldap://empresa.com

This can affect the provisioning?
