Prehistory is the following:
We use cloud SAP SuccessFactors app. We publish it for our users via Azure enterprise apps with SAML SSO configured with SAP support. And till last week everything worked good.
But this week we faced with the problem. SSO stopped working and started to redirect to old test link. We used SAML debugger add-in in chrome and we see this wrong redirection.
I struggled with Azure PowerShell and finally found that old link among others in SPN addresses list.
I used this command
(Get-MsolServicePrincipal -ObjectId "_our app objectid_").Addresses
BUT
I can not correct this list. If I try to create an array of such objects and then
Set-MsolServicePrincipal - Addresses $array
I get an invalid syntax error.
Maybe some PowerShell guru is watching and can guide or paste some idea I would be so much appreciated.
MS support in India says NO. Impossible to change Addresses for gallery apps. SAP support say just delete this app and create from scratch.
