Hi Khaled,
Yes. To convert the Single Sign-On (SSO) authentication to standard cloud-based authentication, we need to convert the federated domain to a standard domain.
For detailed information, you can refer to the following steps:
1. On the ADFS server, connect the Windows Azure AD using Windows PowerShell to the Office 365 tenant.
2. Run the cmdlet Convert-MsolDomainToStandard to convert the current federated domain back to a standard domain. Here is an example:
Convert-MsolDomainToStandard -DomainName domain.com -SkipUserConversion $false -PasswordFile C:\temppassword.txt
3. Then, the previous federate users (use SSO to access Office 365 services) need to sign in to the Office 365 portal and type in the temporary password got from the txt file generated in the cmdlet above. Then, they will change a new password for accessing Office 365 services in the future.
Thanks,
Claud
