permission denied with BSD

[Eduardo Ceva]

Hi, I setup my backup scheme like this. I mount all of my server using NFS under /mnt/backup/servername, for exemple if the server is PIAUI I mount using NFS at /mnt/backup/piaui. All my linux servers works fine bacouse at exports file I include the option no_root_squash, and the backup finish with success every day, but in the BSD this option doesn�t exist, and I get the message "permission denied". I read the man page of exports on BSD and I found the option rootmap. Someone knows how to make the rootmap option works like no_root_squash?   thanks   Eduardo Ceva
