the response format for AuthRequest should be:

{
"Header":{
"context":{
"change":{
"token":4956
},
"_jsns":"urn:zimbra"
}
},
"Body":{
"AuthResponse":{
"authToken":{
"_content":""
},
"lifetime":172800000,
"skin":[
{
"_content":"serenity"
}
],
"_jsns":"urn:zimbraAccount"
}
},
"_jsns":"urn:zimbraSoap"
}

according to xml structure. but when i receive the response,the authToken element contains value as List item rather than simple value.
{
"Header":{
"context":{
"change":{
"token":4956
},
"_jsns":"urn:zimbra"
}
},
"Body":{
"AuthResponse":{
"authToken":[
{
"_content":""
}
]
,
"lifetime":172800000,
"skin":[
{
"_content":"serenity"
}
],
"_jsns":"urn:zimbraAccount"
}
},
"_jsns":"urn:zimbraSoap"
}


the response is included as "authToken":[ { "_content":" ]} instead of "authToken":{ "_content":" "}. is it a bug or something?
