Would you mind elaborating a bit? Are you talking about security, authentication, encryption? Kerberos is primarily authentication. It provides some information to authorization systems built on top of it and has some small authorization conventions for managing the domain. It uses encryption to enable the authentication, but doesn't necessarily enforce any protocol-level encryption on applications using it for authentication. From what I understand, permissions on files under AFS are not really handled the way a simple UNIX filesystem is (uid/gid/perms in the inode, optional acl extensions). Instead, files are owned and permissions granted based on your Kerberos principal for the domain the AFS is in. Essentially, a Kerberos infrastructure is necessary to use AFS, at least a minimal one. And, with a truly minimal Kerberos configuration, I don't think it would be any more secure and probably more poorly performing than an equivalent NFS. -- Boyd Stephen Smith Jr. ,= ,-_-. =. b...@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/\_/ signature.asc Description: This is a digitally signed message part.

You mean '... than an equivalent nis or ypbind' configuration since we are talking authentication here? IIRC, you can enforce ssl / tls with nfs+krb. It seemed pretty fast but I didn't benchmark it.

btw, i just ran across this (looking at perlbal) but this looks related to the 'network file system' conversation. http://www.danga.com/mogilefs/
