Hi. I'm trying to use NFSv4 as it is supposed to work trough NAT (as I know it uses only TCP port 2049). Both client and server are running FC3. After spending lot of time trying and retrying to mount an export, I found the following guide on internet: ---- http://www.vanemery.com/Linux/NFSv4/NFSv4-no-rpcsec.html ---- I followed instructions from this guilde, however Im still getting 'Mount: permission denied' error - even if I try to mount an export from localhost (FS type nfs4 produce the mentioned error, however nfs is working fine on localhost). I guess that the problem is related to KRB (Kerberos-5). My authentication backend is OpenLDAP. I don't want to change. Do I really need KRB to use NFSv4? If yes ... is it posible to use data from OpenLDAP for KRB? Any hint? Best regards, Dezo
