username admin can't login

[yuchangfu]

I use provision/provision.sh to run usergrid on docker.I change the provision.sh as below:
echo "+++ provision.sh"
USERGRID_HOST=localhost
ORG_NAME=Future-Tech
APP_NAME=easybook
ADMIN_PASS=891152

echo "+++ stop running docker containers"
docker stop $(docker ps --quiet)

echo "+++ remove existing container images"
docker rm -f usergrid cassandra elasticsearch portal

echo "+++ start containers"
docker run -d --log-driver=syslog --name cassandra -p 9160:9160 -p 9042:9042 -v "$PWD"cassandra-data:/var/lib/cassandra yep1/usergrid-cassandra
docker run -d --log-driver=syslog --name elasticsearch -v "$PWD"/elasticsearch-data:/data yep1/usergrid-elasticsearch
docker run -d --log-driver=syslog --name usergrid --env ADMIN_PASS=${ADMIN_PASS} --env ORG_NAME=${ORG_NAME} --env APP_NAME=${APP_NAME} --link elasticsearch:elasticsearch --link cassandra:cassandra -p 8080:8080 -t yep1/usergrid
docker run -d --log-driver=syslog --name portal --env USERGRID_HOST=${USERGRID_HOST} -p 80:80 yep1/usergrid-portal

In this file I set password to "891152'
servies run well,but admin can't login and get error below:
