The **csm\_cmdb\_model.customer\_visible\_flag** system property is an additional access control to the CMDB model. If **csm\_cmdb\_model.customer\_visible\_flag** is not set to the recommended value of **true**, then any user with the sn\_esm\_user role and out of the box ACLs will have permissions to the CMDB model. Note that this role tends to be granted to external users. Ensure that the property **csm\_cmdb\_model.customer\_visible\_flag** is set to **true**. ## More information
