Do I understand correctly that if you use LDAP authentication, you still need to manually create all the users in Zabbix frontend? But it’s usually used to not set each user separately ... The only advantage is the use of the same password?

Can you make the automatic addition of an LDAP user? Or how to do it?

"Note that a user must exist in Zabbix as well, however its Zabbix password will not be used."
