Converting OpenID to SAML

Hi,
We’ve set up our Mattermost to be bound with OpenID to google; we now want to switch this to SAML2.0. How will this impact existing users? does every user need adjust this since their usernames are not their emails?

Found out that to do this, the admin will have to convert each user account from openID to email and then from email to SAML2.0; manually one by one by each user. Oh well, this is gonna take awhile

Sorry to hear about the extra work required there, stan - but we do appreciate you following up to share the solution!
