VBO Exchange On-Prem Authentication

[Cia91]

Hello, we are trying to add an on-prem exchange to the Organization we backup via VBO.

I've managed to enable the remote powershell, in fact i can correctly connect from the VBO server with:

Code: Select all

$Session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://exchange.domain.com/powershell/ -Credential $LiveCred -SessionOption $SessionOpt -Authentication Basic

But i'm not able to connect via Veeam. The thing i'm not understanding is what type of authentication Veeam want or support. I see that it tries to use Kerberos, but it then should failback to something else i suppose, or is only Kerberos supported? Is there a way to force Veeam to try with Basic auth or Digest?

Hi Cia91

We support both protocols:
- Basic Authentification
or
- SPN (Service Principal Name) and Kerberos authentication

I suggest to contact our customer support team. A support engineer can investigate your logs and provide you with a solution based on your environment. Unfortunately we cannot do so over a forum post.

May I ask why Kerberos is no option for you?

Best,
Fabian

Hello, Kerberos is not an option because the VBO server is not domain joined.

We are working on opening a case support, i opened this forum post because the documentation is quite lacking and maybe it will be helpfull for other, so Veeam support various mode, but you can't choose them i suppose it work in a failback mode where it tries for kerberos, then it failback to some other and so on...

NTLM is not supported?

Can you please share the case number with me?
The missing information in the documentation is something I'm currently discussing internally.

Best,
Fabian
