Still facing issue...

User is successfully created, /etc/elasticsearch/shield/users is modified:  
cat /etc/elasticsearch/shield/users  
lmcnise:$2a$10$OhPJkrrlu4RlV4F7/sAUOeFRxEIEcjRUbDoS/C31Y7ITeWZ.74K52

But:

> [2016-03-31 12:05:22,862][DEBUG][shield.authc.esnative] [datastorage] user not found in cache, proceeding with normal authentication  
> [2016-03-31 12:05:22,868][DEBUG][shield.authc.esusers] [datastorage] user not found in cache, proceeding with normal authentication
