Only one user can be logged in / created

Hi,
Pulsar manager is quite helpful in administering the cluster, but it has one disadvantage.

It is not possible to add more than one user - there can only be one administrator.
This might not be a big problem except that this user can only be used by one person at a time.
When we work in a team, we interrupt each other all the time. When I am working with pulsar manager and another person opens it, I get logged out immediately.

I tried using two PM instances, however the effect is the same :(

Is there any solution?
