We've had an issue for a while that we've just identified what looks like the cause.
When logging in to the console with MYDOMAIN\UserName, it takes exactly 50 seconds (+/-2) from pressing enter to being logged in. The 50 seconds is reproducible every time.
Looking at the OrionWeb.log (from C:\ProgramData\SolarWinds\Logs\Orion\), I see the following occurs every time someone tries to log in:
WARN SolarWinds.Orion.Web.Authentication.Windows.DirectoryServices - (null) Can't connect to domain 'OTHER-DOMAIN-WE-TRUST.com': System.Runtime.InteropServices.COMException (0x8007203A): The server is not operational.
As soon as this warning appears in the log file, the user is then logged in straight away.
The domain OTHER-DOMAIN-WE-TRUST.com is a domain of a partner organisation that my organisation's domain trusts, as a one-way trust.
Why is it trying to authenticate against that domain first, instead of using the MYDOMAIN in the login field?
