LDAP multiple email parsing error

Description:

LDAP entries of user with multiple email addresses fail to parse rendering them unable to login.

Steps to reproduce:

Try to login or sync data of a user with multiple email LDAP entries.

Expected behavior:

The first email that has been found should be used as the users email address.

Actual behavior:

Login and data sync fails for users with multiple email addresses.

Server Setup Information:

• Deployment Method: docker-compose
• Number of Running Instances: 1

Additional context

This is similar to a previous issue #2642 that has supposedly been fixed. I'm using FreeIPA as the LDAP provider.
