[Vijayakumar Ramdoss]

Hi All,We are recently start leveraging the Solr 5.5 version in the Cloud mode. 
Even enabling the security in the SolrCloud. Its not working looking your 
advice to debug the issue. 

cat security.json{"authentication":{   "class":"solr.BasicAuthPlugin",   
"blockUnknown": true,   
"credentials":{"solr":"IV0EHq1OnNrj6gvRCwvFwTrZ1+z1oBbnQdiVC3otuq0= 
Ndd7LKvVBAaZIF0QAVi1ekCfAJXr1GGfLtRUXhgrF8c="}},"authorization":{   
"class":"solr.RuleBasedAuthorizationPlugin",   
"permissions":[{"name":"security-edit",      "role":"admin"}]   
"user-role":{"solr":"admin"}}}

ThanksVijay
