[NFS-Ganesha-Support] ganesha.nfsd and krb5

I am a new user, compiled the sources with HAVE_GSSAPI and would like to be able to choose to run with or without kerberos. Is there a config option for this or I have to compile 2 versions? With Active_krb5 false it still gives "gssd_refresh_krb5_machine_credential failed"
