signed inn this morning after my upgrade and saw this warning
Jamf Pro detected one or more accounts using the same email address. Jamf Pro will start blocking SSO access for accounts using duplicated emails when Jamf Pro is configured to use email as Jamf Pro User Mapping. To ensure all accounts can sign in, check that no accounts are using the same email address in User accounts and groups
not sure i like this at ALL
Monday
I have received this error also and couldn't find any duplicates, there are a couple accounts that don't have emails assigned to them and I'm wondering if that what's triggering this error.
