We are using this extension. We have 12 websites and we set Customer Sharing as "Global". We also have option "Create user if not exist" set to "Yes"
Issue is we can not login with same customer on another website. It show me an error:
The auto-provisioning process failed: Customer email already exist
Can you let me know what we need to do to make it works? We need to set Customer Sharing as "Global"
Thank you
Right now the extension is able to provision an user that does not exists previously in any other store, but not to link an existed user on the specific store.
Take in mind that each websites is consider as unique Service Provider able to be connected with a Identity Provider. It seems that in your scenario, you are connecting all the stores to the same IdP (not the common use)
I can implement the ability of link an existed user to the specific store, but I will need to add an extra option on the settings to enable it because in other scenarios, where you connect with different IdPs, this can provoke a security issue.
P.S Do you have license for all those sites?
