Phil Zampino commented on KNOX-1214:
------------------------------------
Since we've started actually parsing the XML from referenced provider
configurations, the attribute-style parameters are no longer supported. (At the
time of the demo, there was no parsing/validation of XML provider
configurations).
Only the element-style parameter specification is supported for XML. Also,
please note that JSON and YAML formats are now supported for describing
provider configurations.
e.g., JSON
{code:java}
{
"providers": [
{
"role": "authentication",
"name": "ShiroProvider",
"enabled": "true",
"params": {
"sessionTimeout": "30",
"main.ldapRealm": "org.apache.knox.gateway.shirorealm.KnoxLdapRealm",
"main.ldapContextFactory":
"org.apache.knox.gateway.shirorealm.KnoxLdapContextFactory",

"main.ldapRealm.userDnTemplate":

"urls./**": "authcBasic"
