for Google Workspace / for Microsoft 365
I'm trying to synchronize the accounts between Active Directory and HENNGE Access Control, but I've received an error.
And I'm wondering if the reason is because the first name and last name (givenName/given_name) of user attributes are left blank?
Yes, your understanding is correct.
The first name and last name fields must contain more than 1 character for the account synchronization to run properly.
