Error Configuring ADFS in AD Connect - IndexOutOfRangeException

Question

I am configuring ADFS in AD Connect and receive an IndexOutOfRangeException when transitioning from the Credentials page to the Service Account page. Below is the relevant info from the log. Any idea how to correct this?

[13:35:12.097] [ 28] [INFO ] Page transition from "Credentials" [ConfigFederationServerCredentialsPageViewModel] to "Service account" [ConfigServiceAccountPageViewModel]

Hi Vijisankar,

Unfortunately, this didn't solve the issue. The exception that I see in the log is different than the one shown in the solution. What I see in the log is for the page transition from Credentials to Service Account:

[13:48:25.828] [ 11] [INFO ] Page transition from "Credentials" [ConfigFederationServerCredentialsPageViewModel] to "Service account" [ConfigServiceAccountPageViewModel]
[13:48:25.877] [ 11] [ERROR] RootWizardPageViewModel: An unhandled exception occurred during a page load.
Exception Data (Raw): System.IndexOutOfRangeException: Index was outside the bounds of the array.

Answer 3

Hi,

Could you please check if the ADFS service account is in the format of [e-mail] instead of “domain\username” (on the ADFS server itself via services.msc)?

Vijisankar 

Answer 4

I have the same issue and when I looked yesterday the AD FS service account is account@domain name 

Your question does not state how it should be or if it should be changed Can you confirm the exact format required ?

Here is the error condition

 Page transition from "Credentials" [ConfigFederationServerCredentialsPageViewModel] to "Service account" [ConfigServiceAccountPageViewModel]
[12:53:18.447] [ 26] [ERROR] RootWizardPageViewModel: An unhandled exception occurred during a page load.
Exception Data (Raw): System.IndexOutOfRangeException: Index was outside the bounds of the array.
   at Microsoft.Online.Deployment.Framework.MVVM.Validation.ValidateUsernameFormatAttribute.Format(String username, UsernameFormat desiredFormat)
   at Microsoft.Online.Deployment.OneADWizard.UI.Controls.Credentials.InputCredentialsViewModel.set_Username(String value)
   at Microsoft.Online.Deployment.OneADWizard.UI.WizardPages.ConfigServiceAccountPageViewModel.OnLoad(NavigateDirection direction)
   at Microsoft.Online.Deployment.Framework.UI.WizardPages.RootWizardPageViewModel.ActivatePage(IWizardPage page, NavigateDirection direction)
[12:53:18.565] [  2] [ERROR] A terminating unhandled exception occurred.

Answer 5

So here’s what you need to do:

1. Log into the ADFS servers
2. Open services.msc
3. Locate the ADFS service, right-click, properties
4. Go to the Log On tab
5. Change the format of the service account from [e-mail] to domain\name (keep the same account, do not change it)
6. Restart the ADFS service

Then AAD Connect won’t have this problem.
