Configuring Azure AD for authenticating on vCenter Server 8.0 U2 will be able to authenticate through the vCenter GUI but not PowerCLI. The following error appears when authenticating using the PowerCLI cmdlet New-OAuthSecurityContext:
Authorized party is not valid
vCenter Server 8.0 U2 or higher
This is issue is caused by a limitation in internal APIs. It is currently not possible for client applications other than the vCenter GUI to authenticate using Azure AD.
The fix will be available in the upcoming release of vCenter version. There is no workaround for this issue.
