While connecting to a specific tenant if Plugin registration tool will give exception

While connecting to a specific tenant if Plugin registration tool will give exception
and at the same time try to access the web services from platform box, if those wo;t work then follow the below

#1 check the three groups(PrivReportingGroup{....},ReportingGroup {...},SQLAccessGroup{...}) with id in {...} from the security -> login of database
#2 make all the three groups to be available in MSCRM_config as well as the tenant_MSCRM tables by giving the following "Roles"
PrivReportingGroup{....} : CRMReaderRole
ReportingGroup {...} : none
SQLAccessGroup{...} : db_owner

#3 if possible restart the app pool in each application and platform servers

this happens sometimes if we are just importing the tenants, so it will have unnecessary groups from the earlier server.
All these things need to be deleted.
