EMC Atmos 2.0 - Failed to initialize tenant

Hi there,

I installed and configured the evaluation copy of EMC Atmos 2.0. Everything seems working and I can access the web interface on MYSERVER/mgmt_login. When I logged in successfully I try to create a new tenant.

I go to "Create Tenant", choose "Authentication Source: Local", "Tenant Name: Test" and "UID Shared Secret Store Provider: LockBox". When I hit submit I got the message:

Error: Failed to initialize tenant.

Can someone give me a hint what is going wrong here or where to start to investigate the problem? Maybe some kind of logfile I could take a look into?

Thanks alot,

best regards.
