Unable to login to Opendistro kibana with the default admin credentials for the first time

Hi Team,

I have set up 3 node cluster in windows and ES is up and running and the kibana page is loading however im not able to login to using the admin/admin credentials. pls help, really stuck here…

server.host: ""
server.port: 5601
elasticsearch.ssl.verificationMode: none
elasticsearch.username: kibanaserver
elasticsearch.password: kibanaserver
elasticsearch.requestHeadersWhitelist: ["securitytenant","Authorization"]

opendistro_security.multitenancy.enabled: true
opendistro_security.multitenancy.tenants.preferred: ["Private", "Global"]
opendistro_security.readonly_mode.roles: ["kibana_read_only"]

# Use this setting if you are running kibana without https
opendistro_security.cookie.secure: true

newsfeed.enabled: false
telemetry.optIn: false
telemetry.enabled: false
security.showInsecureClusterWarning: false
# To configure a WMS map server for use with Kibana, see:
# https://opendistro.github.io/for-elasticsearch-docs/docs/kibana/maptiles/
map.includeElasticMapsService: false

Please note I have disabled the opendistro.security in elasticsearch.yml. Is that the reason ?
