If you have multiple VSEs assigned to one Registry, Is there a way using DevTest portal to only view the VSE you are working on through access control?
Have you had the chance to look at Resource Groups?
Resource Groups - DevTest Solutions - 10.3 - CA Technologies Documentation
Resource groups are one or more DevTest Servers or VSEs. Define resource groups to determine the resources that a user or a project can access.
There is also a document regarding DevTest Using Resource Groups with LDAP/LDAPs - CA Knowledge
Hope it helps.
Thanks this worked
