I already posted this question in https://www.virtualmin.com/node/10659, but not as an issue, so probably it slipped your attention:
Let's clarify... My users and groups are in an LDAP directory. Using virtualmin I already created a virtual server on machine A with user X. So user X is already in the LDAP directory. Now I want to create a virtual server on machine B for user X (because the load on server A reaches its limit). Is there any option to prevent re-creation of this user. If not, is it possible to implement this option. What I really want is the full virtual server setup without the creation of a user and group (because it is already there).
