Impossible to login with microsoft business account

Describe the bug
Impossible to login with microsoft business account

To Reproduce
When we use the following function OIDAuthorizationService.discoverConfiguration(forIssuer: url) using as url "https://login.live.com", everything goes right. Since the url "https://login.live.com" is not working with business account, we wish to use the following url "https://login.microsoftonline.com" or "https://login.microsoftonline.com/common/v2.0/", but the function OIDAuthorizationService.discoverConfiguration reply with the following error

Error Domain=org.openid.appauth.general Code=-5 "JSON error parsing document at 'https://login.microsoftonline.com/common/v2.0/.well-known/openid-configuration': Invalid URL: issuer" UserInfo={NSLocalizedDescription=JSON error parsing document at 'https://login.microsoftonline.com/common/v2.0/.well-known/openid-configuration': Invalid URL: issuer, NSUnderlyingError=0x600000a0f360 {Error Domain=org.openid.appauth.general Code=-2 "Invalid URL: issuer" UserInfo={NSLocalizedDescription=Invalid URL: issuer}}}

so for us it's impossible to login with microsoft business account. The url provided is correct, since the same url works well on android.

Expected behavior
The function OIDAuthorizationService.discoverConfiguration should complete without error.

Environment

• Device: All iOS devices
• OS: All iOS version, starting from iOS 10.

Start by tracing OIDAuthorizationService.discoverConfiguration(forIssuer:) and the response from the Microsoft common v2.0 .well-known/openid-configuration endpoint. Compare its issuer value with the URL passed to discovery and review the existing discovery-related tests, if present. Done means business-account discovery completes without the reported invalid-issuer error and existing providers continue to work.
