Extra Admins - no Webmin User being created

Virtualmin 3.52 Pro Webmin 1.401 Centos5

I addead an extra admin user to one domain and it seems to work fine. Than I tried adding a second one. The process seems to work, but no webmin user is created, so the user is not allowed to login.

I have tried different domains with no luck. I even tried it on a second server with mostly the same config, still not happening.
