Hi,
I have these:

[zimbra@ldapmsg ~]$ zmlocalconfig -s |grep password
antispam_mysql_password =
antispam_mysql_root_password =
ldap_amavis_password = abc123
ldap_bes_searcher_password = abc123
ldap_nginx_password = abc123
ldap_postfix_password = abc123
ldap_replication_password = abc123
ldap_root_password = abc123
mailboxd_keystore_base_password = zimbra
mailboxd_keystore_password = qS5zKMcZ
mailboxd_truststore_password = changeit
mysql_root_password = Au93LYSvP19WRZ4yhyuU7H1wEGV.gjx
zimbra_ldap_password = k_Tf1Xqpcz
zimbra_mysql_password = pXJb4glh5PbDT9cszBGKof6Q4
zimbra_vami_password = vmware

1) what's the difference between ldap_root_password and zimbra_ldap_password ?

2) how do I change mysql_root_password, zimbra_ldap_password and zimbra_mysql_password ?

TIA
