Lets recap: 1. Requirements: - Linux or Solaris - NFS automounter set up at /net - Kerberos5 configured for realm EXAMPLE2.COM, rpc.gssd running - A NFS server (version 4 only) nfsserver.most.gov.cn exists in the realm MOST.GOV.CN, with a subdir of test3
2. Goal: A user provides his password to obtain a ticket for [email protected] (optionally [email protected], if this is a requirement to do a mount), and is then able to cd into /net/nfsserver.most.gov.cn/test3, and do a successful ls -al there Is that possible?

You'll need to have Solaris krb configured which stores its config in /etc/krb5 not /etc as is the MIT default. You'll also need read access to /etc/krb5/krb5.conf and have the system properly configured to do NFS with krb in general (read the Solaris 10 online docs). Beyond that, whether a user kinit'ing is enough depends on which version of NFS you are using. On the client side NFSv3 sec=krb5p shares will automount if the user triggering the mount has a krb cred in their ccache (klist will show that) and does not require any keys in the system keytab nor does it require root to have a krb cred in general. NFSv4 on the other hand does require that the root on the NFS client system have a krb cred in its ccache. This can be done either by running kinit as root or having at least one set of keys for either the root/<host> or host/<host> service princ in the system keytab which will be automatically used to acquire a krb cred for root. On the client system "nfsstat -m" will show what version of NFS is being used. -- Will Fiveash Oracle Solaris Software Engineer -- Wang Shouhua - [email protected] 中华人民共和国科学技术部 - HTTP://WWW.MOST.GOV.CN
