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
irisserv
ERROR: User irisserv not found
root at noordo:/var/log/kwartz# samba-tool spn list noordo
noordo
ERROR: User noordo not found

but
ldbsearch cn=irisserv servicePrincipalName
works...
