The issue you are facing:
When I connect through ENTRA SAML, it create a new user with mail address as home but there is already a profile with UID as home.
Is it possible to map existing users?
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Login with LDAP, it create a user if it not already exists
- Logout then Login with SAML auth and it will create a new user
