Searches fail for users who are members of groups where the authorityName contains double quotes

The ACS REST API and also the AuthorityService allows for the creation of groups where the group id (authorityName) can contain double quotes. When a user is assigned to groups where the authorityName contains double quotes all searches performed against the Search Services by that user fail.

Environment:
ACS 6.1
Search Services 1.3.0

Actions Performed:
Created a group using the Public REST API for the creation of where the id contains a double quote
“…/alfresco/versions/1/groups”

{ "id": "mytest\"group", "displayName": "mytestgroup", "isRoot": true }

Assigned a user (testyone) as member of ‘mytest"group’

Executed the following search as the testyone user
“../search/versions/1/search”
{
"query":

{ "query": "Alfresco*" }

}

Expected Result:
The search returns the expected results

Actual Result:
An error is returned
error":

Notes:
When the testyone user logs into Share a blank page is displayed
When the testyone user logs into the Digital Workspace searches fail
The following error looks to be generated in the solr.log when executing queries by the testyone user:
