Once you have logged in, youcould execute some commands to configure the connection to Office 365: 

  • Register-PSRepository -Default: registers a PowerShell repository
  • Get-MsolDomain: displays the registered domains in Azure Active Directory.
  • GetMsolDomainFederationSettings: get the settings for a federated domain
  • Set-Msoldomain -Name <YOUR_DOMAIN> -isdefault: set as default one domain
  •  

  • Set-MsolDomainAuthentication  -DomainName <YOUR_DOMAIN>  -Authentication federated: set as federated a specific domain.

In order to connect Office 365, one can use the following script:

$dom = "<Your demain>"
$BrandName = "<Your company>"
$LogOnUrl = "https://<Your Soffid IdP>/profile/SAML2/POST/SSO"
$LogOffUrl = "https://<Your Soffid IdP>/profile/SAML2/POST/SLO"
$ecpUrl = "https://<Your Soffid IdP>/SAML2/POST/PAOS"
$MyURI = "<Your Soffid IdP>"
$MySigningCert = "<Your certificate in Base64>";
# "MIIGaDCCBVCgAwIBAgIQAWdkq9pxzP/bK+Mlym5y5zANBgkqhkiG9w0BAQsFADBeMQswCQY....
$Protocol = "SAMLP"
 
# To enable
Set-MsolDomainAuthentication -DomainName $dom -FederationBrandName $BrandName -Authentication Federated -PassiveLogOnUri $LogOnUrl -SigningCertificate $MySigningCert -IssuerUri $MyURI -LogOffUri $LogOffUrl -PreferredAuthenticationProtocol $Protocol
 
# To disable
# Set-MsolDomainAuthentication -DomainName $dom -Authentication Managed
