Unable to access XS Administration Tool URL

Hi,

We have MDC for HANA.When I am trying to open XS Administration Tool i.e the URL (http://hostname-TenantDB:8000/sap/hana/xs/wdisp/admin/) itself I am getting below error.

403 Access denied

You do not have the permissions to access this resource

I checked there are some modification rule is in place.Are they responsible for this.If Yes then how to fix this?Simply commenting out the rule will resolve this?

Hostname:/usr/sap/<SID>/HDB00/hostname/tmp> more default_mod_rules_admin_ui

#These are the default modification rules used for restricting accessto the Admin UI to SingleDb and SystemDb users only!

if %{SID} != ---

RegIForbiddenUrl ^/sap/hana/xs/wdisp/admin/(.*) - [break]

Hostname:/usr/sap/<SID>/HDB00/hostname/tmp>

Thanks,
