BYOIDP - Mendix Cloud SSO - not using email for username
Going through the configuration steps of Single Sign On with Mendix Cloud and our company IDP, I ran into a question on step 4. Step 4 is configure claim mapping. Mendix automatically selects email for the user name mapping, however I want to use something else. My question is if I use something else what happens to the accounts that have already been setup using their email? From the documentation Set Up an SSO (BYOIDP) | Mendix Documentation – “The user’s email address is used to associate a user’s existing account within Mendix with the user’s account at your IdP. This means that any existing Mendix account is linked to their IdP account for authentication, rather than a new Mendix account being created for them.” That sounds all good in theory, but when I decided to use the test link they provide It would force me to create a new account. I didn’t complete this new account creation process for fear of messing up my account and then trying to figure out how to fix.
if you use 'something else' and the Mendix platform cannot find an existing account for the value that was received - it assumes it's a sign-on for a yet non-existing account and indeed redirects the process into a platform signup.
I'm not sure how you would envision a different kind of logic?
