[Samba] classic upgrade error

[Arnaud FLORENT]

Hello

i have a problem after classicupgrade on ubuntu 14.04/samba 4.3.11

i know this version is not supported, sorry no way for the moment to do 
ubuntu upgrade...


before migration

netbios name in smb.conf (irisserv) did not match dns hostname (noordo)

so AD was provisionned but with irisserv
and there are no servicePrincipalName in irisserv ldap entry...


is there a way to fix this?

Thank you
