Login is currently disabled because the license could not be determined

hi all,

i followed these instructions:
https://www.elastic.co/guide/en/x-pack/v5.0.0-alpha4-docs/installing-xpack.html#xpack-enabling
to install x-pack receive the error:

Login is currently disabled because the license could not be determined

this is rhel7, elastic and kibana installed from rpm.
the two nodes show:

[root@node100 elasticsearch]# /usr/share/elasticsearch/bin/elasticsearch-plugin list
x-pack
[root@node100 elasticsearch]# /usr/share/kibana/bin/kibana-plugin list
x-pack@5.0.0-alpha4-SNAPSHOT

[root@node101 Linux]# /usr/share/elasticsearch/bin/elasticsearch-plugin list
x-pack
[root@node101 Linux]# /usr/share/kibana/bin/kibana-plugin list
x-pack@5.0.0-alpha4-SNAPSHOT

elastic.yml has the following settings on both hosts:

xpack.security.enabled: false
action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*

even so, after i restart kibana and elastic i see the message " Login is currently disabled because the license could not be determined. " and i cannot interact with the Username or Password fields

it's a two node cluster:
"_nodes" : {
"total" : 2,
"successful" : 2,
"failed" : 0

a similar problem in another thread was resolved by installing x-pack on all hosts in the cluster but i don't think that is my problem here. any ideas?

thank you

When you start ES and KB, does it show something like loaded plugin [x-pack] in the logs?
