Kerberize .local domain (Bonjour problem)

Hello and Happy New Year to all Ive setup an OD master using the .local name and Im trying to kerberize the VPN service. The kerberos daemon is running but when im trying to run the slapconfig I keep getting this: sudo slapconfig -kerberize diradmin SERVER.xxx.LOCAL diradmin's Password: xxxx Hostname server.xxx.local is from Bonjour Skipping Kerberos configuration. Also there is no "Kerberize" button in any service. Is there any way to Kerberize this server or do I have to setup again? If I dont want to use the company's internet domain name .com waht are the valid names that should I use (.private, .lan.....) Kostas
