mount.nfs: access denied by server while mounting (Kerberos authentication)
- by Nick
There's plenty of references to this error on Goggle, and even a question here with the same title, but it seems that "access denied by server while mounting" is a catch-all error. I've tried suggestions that others have used to fix this problem, but they did not work in my case.
I'm trying to set-up a Kerberos-based NFS file server with shared homes for a Linux network. I'm using Ubuntu 11.04 Servers and clients.
When trying to mount a share using:
mount 192.168.1.115:/export/home/ /media/tmp
I get:
mount.nfs: access denied by server while mounting 192.168.1.115:/export/home/
This is the same if I mount it from a client machine or from the server itself.
On the server, in /var/log/syslog I get:
Aug 25 06:22:37 nfs mountd[1580]: authenticated mount request from
192.168.1.115:835 for /export/home (/export/home)
Aug 25 06:22:37 nfs mountd[1580]: authenticated unmount request from
192.168.1.115:766 for /export/home (/export/home)
Which is odd, since it says it's authenticated the request, not denying it.
/etc/exports:
/export *(rw,fsid=0,crossmnt,insecure,async,no_subtree_check,sec=krb5p:krb5i:krb5)
/export/home *(rw,insecure,async,no_subtree_check,sec=krb5p:krb5i:krb5)
On client:

Any suggestions I could try?
