nfsv4 mount using kerberos 5p fails after upgrading to ontap 9.9.1
- Ontap 9.9.1
- kerberos 5p
When an export policy rule has been configued to allow only kerberos 5p connections and the system is running 9.9.1 or later.
- Is necessary to specify krb5p mount option on the client for mont to be successful as as security flavor negotiation would not work properly
- Automount configurations may not allow mounting nfs resources
If NFS sktraces are enabled the following subsequent lines would appear in sktrace.log when the issue is hit
