i will try this asap

in AD smb.conf there was netbios name = noordo (dns hostname)

if i change to netbios name = irisserv
and restart samba
servicePrincipalName attributes are created...

i did not see any warning about this
is it supported?

root at noordo:/var/log/kwartz# samba-tool spn list irisserv

root at noordo:/var/log/kwartz# samba-tool spn list noordo

ldbsearch cn=irisserv servicePrincipalName
