I've got a problem since I upgrade in 3.3.8906.0.
The "Domainless Username" option is activate for all web interface types but on first login after IIS reset, I have this error message : The account name is invalid. It is expected to be formatted either as 'DOMAIN\user' or 'user@domain'.
If I log in with 'DOMAIN\user' once then close my browser with cleaning cache, I'm able to log in only with my username.
But if I reset IIS again, I'll have to log in for the first time with 'DOMAIN\user' for each WebUI.
Can you help ?
