User/Group created during an unsuccessful virtual server creation is not deleted

Due to a configuration problem, a virtual server was not successfully created. However, the creation process did created a User and Group before being halted.

After resolving the configuration problem and on re-creating a virtual server, I got this error:

"Failed to create virtual server : A unix user called mydomain.com or group called mydomain.com already exists"

Shouldn't VMpro automatically undo any steps executed after an unsuccessful virtual server creation?
