SCIM: Sync question

I’ve successfully set-up SCIM Bridge with our Google Workspace instance.

However, I have a couple of users that were already set-up 1password with a different e-mail (same domain).

This email does not exist anymore in our GW directory as a primary account, but IS set as an Alias to the ‘correct’ E-mail.

as an example:

current email in 1password before sync: j.smith@domain.com

correct email in GW: john.smith@domain.com

j.smith is in the group ‘all users’ to be synced with gw

j.smith is also in another group called ‘office’ in 1password

john.smith is in a group called ‘office’ in GW.

The result is that the scim bridge did ‘sync’ de account so that it now is manageable via idp (GW), but it did NOT add it to the office group. In fact, it actually removes it from that group. That kinda makes sense because the email doesn’t match; j.smith doesn’t exist in GW as a primary email (only as an alias). 

so now I have 2 questions.

1. How come the account was ‘taken’ by the scim bridge/1password while the primary email didn’t match?
2. How do i fix this, so that I don’t have to temper with the GW account (aka the result is that the j.smith account changes to john.smith)

Anyone able to make sense out this?
