Steps to reproduce:

1. Fresh Zabbix 6 install
2. Enable LDAP auth
3. Would like to disable auto-login as each login should use LDAP.

Result:
User can change their profile to enable auto-login and the auto-login tickbox is ticked by default. the risk associated with this is that an LDAP account is removed from the LDAP server, yet a user can still login for 30 days with their cookie.
Expected:
When using external auth methods, no cookies should be used for subsequent sessions. Parameters like auto-login and auto-logout should be set system-wide, and not per account.
