And since you have to have AD/Azure AD for Windows logins if you want single-password (not necessarily SSO) your source of truth is now an LDAP server.
I don't love this state of affairs as I'd rather just use my password manager for everything (and it's particularly bad when you have a mix of on-prem stuff that does AD and then other cloud stuff that doesn't), but I suppose it probably works well for shops that use exclusively cloud services.
That’s fine when you’re a sole developer or a small team but the moment your organisation grows you need SSO.

Most cloud services do support AD (eg via SAML) but hide that option behind an enterprise subscription.
