To force the use of HTML form-based authentication, use the solution below.
Cause
The window is shown due to the automatic NTLM-based authentication method introduced in v9.
Solution
For 9.5 update 4 and later form-based authentication can be disabled solely by changing value of the following parameter in web.config file ( default location C:\Program Files\Veeam\Backup and Replication\Enterprise Manager\WebApp) to false:
<add key="useWindowsAuth" value="true"></add>
For earlier versions:
<add key="useWindowsAuth" value="true"></add>
For earlier versions:
- Open the Internet Information Services (IIS) Manager console on your Enterprise Manager server.
- Locate the VeeamBackup site.
- In the Default Document options, add Login.aspx to the top of the list.
- In the Authentication options, disable Forms Authentication method.
- In the Modules, remove the MixedAuthenticationModule2 module.
- Open the following files using notepad and replace "<a href="/">Home</a>" with "<a href="/default.aspx">Home</a>" :
%programfiles%\Veeam\Backup and Replication\Enterprise Manager\WebApp\js\veeam-configuration.js
%programfiles%\Veeam\Backup and Replication\Enterprise Manager\WebApp\js\release\app.min.js - Restart the VeeamBackup website using IIS and clear the cache of your Internet browser.
