Email verification is reset at every login with ldap

Description:

In my setup "E-Mail verification" is globally disabled.
Every time a ldap user logs in to Rocket.Chat the email verified state is set to "false".
No notifying mails are send because the user has no verified mail address.

If i create a local user everything works as expected.

Steps to reproduce:

1. Create an LDAP connection
2. Disable email verification
3. set User mail address to "verified"
4. login with this user account

Expected behavior:

User has a verified mail address and gets mail notifications.

Actual behavior:

User has a valid mail address.

Kind regards

Start with the LDAPHandler login flow and the LDAPSync user-data synchronization shown in the logs, reproducing the issue with email verification disabled and a pre-verified LDAP user. Done means the user's email remains verified after login and notification emails are not suppressed because synchronization resets the verification state.
