Ontap 9.9.1
NFS
kerberos 5p

Issue

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

[1:0] Nfs4Req_5:  CurrentFlags before NGProcessExportCheck: cfs=0x1004, EAI=0x0
[1:0] Nfs4Req_5:  Result EXPORT_NOACCESS: Result=3106
