My company has purchased multiple domains on Slack.com
EX:
https://mycompany-admin.slack.com
https://mycompany-hr.slack.com
https://mycompany-incidents.slack.com
We want to configure SSO with Azure to each of these domains.
I'm able to configure azure enterprise application Slack to link to one domain and set up SSO with slack- all peachy-keen.
The problem is that I cannot reuse the entity ID (https://slack.com) for more SSO's. So, I have https://mycompany-admin.slack.com configured properly, but when trying to create a SSO for https://mycompany-hr.slack.com, I cannot re-use https://slack.com as entity ID.
Does anyone know a workaround? Multiple domains on one app, can't point at each domain, and can't create multiple SSO configurations due to Identity ID reuse.
Appreciate your time and also thank you for sharing your findings here. Could you please accept above your answer which might be beneficial to other community members reading this thread and let us know if you have any further question.
Disregard- found answer. Can use domains as unique ID's as long as I configure target app to broadcast the domain as the unique ID as well

I have 2 SAAS apps on Azure where both with the same entity ID, could you please guide me how do we set that unique ID for an app on Azure.
Any manifest code change or how if you could please guide
Unfortunately you cannot use the same entity ID for 2 different Enterprise Applications in Azure- but if your app creates a unique domain, you can point each SAML authentication at that separate unique ID.
EXAMPLE:
Entity ID: https://slack.com
Can also be: https://uniquedomain1.slack.com
Note in this example you'll have to configure the app itself to send it's SAML response FROM https://uniquedomain1.slack.com. Not all apps can do this.
So with this method, we can have separate enterprise applications for Slack- Slack1 and Slack2, where Slack1 points at https://uniquedomain1.slack.com. The other points at https://uniquedomain2.slack.com. Unfortunately, they cannot both point at https://slack.com. A unique domain is required.
