Despite that, mount attempts continue to fail with the the following error, indicating that ArcFour is still being used:
7/24/2019 16:46:34 <node-02> ERROR secd.nfsAuth.problem: vserver (<test-svm>) General NFS authorization problem. Error: RPC accept GSS token procedure failed [ 12 ms] Acquired NFS service credential for logical interface 1035 (SPN='nfs/<test-svm.realm.com@REALM.COM>'). **[ 18] FAILURE: Failed to accept the context: Unspecified GSS failure. Minor code may provide more information (minor: Encryption type ArcFour with HMAC/md5 not permitted).
Is there another location I need to be specifying which encryption type Kerberos should be using?
