Login option is shown after uninstalling the Microsoft Azure Active Directory Single Sign-On (SSO) (Pro)

After uninstalling the Microsoft Azure Active Directory Single Sign-On (SSO) (Pro) this is how the login looks:

When looking at the Global Administration > Extensions > Licenses table, we can see Configuration Pages for Microsoft Azure Active Directory Single Sign-On (SSO) (Pro).

After uninstalling it this is how the login page looks:

Checking again the Licenses table, we can see Identity OAuth (Pro) and Microsoft Azure Active Directory Single Sign-On (SSO) (pro) API .

After uninstalling Microsoft Azure Active Directory Single Sign-On (SSO) (pro) API this is how the login looks:

After uninstalling Identity OAuth (Pro) the AzureAD login option has disappeared.

However, after a while, when going on the login page there is a warning shown again:

There is one more dependency extension listed - Identity OAuth Integration (API) - in the Licenses table.

When trying to login with the XWiki credentials, I am redirected to another login page with the URL https://tryazureadapp.demo.xwiki.com/xwiki/bin/loginsubmit/XWiki/XWikiLogin

Even if I enter my XWiki credentials, the login is not done. I needed to restart the instance to have again access to the wiki.

After the restart, here is how the login page looks, with a Broken Azure AD option:

Now, I'm able to login using the XWiki account credentials.

Going on the Global administration > Extensions > Licenses, I see that the Microsoft Azure Active Directory Single Sign-On (SSO) (Pro) appears again in the table:

Thus, I need to restart the uninstall process of the AzureAD app, plus all its' four dependencies.

So then, all four dependency extensions seem to need to be uninstalled for a complete removal: Configuration Pages for Microsoft Azure Active Directory Single Sign-On (SSO) (Pro), Identity OAuth (Pro), Microsoft Azure Active Directory Single Sign-On (SSO) (pro) API and Identity OAuth Integration (API).

In the meantime, I have updated the installation page on the app store with the need to uninstall these four dependencies when wanting to uninstall the Azure AD application. https://store.xwiki.com/xwiki/bin/view/Extension/MicrosoftAzureSSO/#installation

These problems are caused by an Identity OAuth issue xwikisas/identity-oauth#12
So after the fix is applied, it should be enough to only uninstall the Microsoft Azure Active Directory Single Sign-On (SSO) (Pro) for the login to work properly.

Note that when you uninstall Microsoft Azure Active Directory Single Sign-On (SSO) (Pro), the AzureAD.AzureADConfig page is not marked by default to be deleted (since it was modified when Azure account information was added) and should be manually checked . See the screenshot below

In case the application was uninstalled and you forgot to check for the AzureAD.AzureADConfig page to be deleted, you can still delete it manually for the uninstall to be complete.
