GSS, Shared Key and Kerberos support is currently broken in master branch. It is indeed impossible to set any flavor for sptlrpc, whereas it is gssnull or ski or krb5
{n,a,i,p}
.
For instance, when doing 'lctl conf_param lustre.srpc.flavor.default=krb5n' or 'lctl set_param -P lustre.srpc.flavor.default=krb5n', the command returns no error, but the value is never applied.
The commit introducing this regression is the following, and aims at making 'lctl set_param -P' functional:

As mentioned in this patch's comment, "currently virtual attributes failover.nid, sptlrpc, and quota
are not fully supported. They will be addressed in later patches".
As I understand 'lctl set_param -P' needs more work to make it work for sptlrpc, the patch should not break 'lctl conf_param' functionality for sptlrpc.
