Why does ldap_bind fail if the password is in Cyrillic?

Question

PHP

Users are authorized through LDAP and everything works fine, except for those who have a password in Cyrillic. The ldap_bind function returns false. Maybe someone came across.

Answer 1

ldap_set_option($ldap, LDAP_OPT_PROTOCOL_VERSION, 3);
ldap_set_option($ldap, LDAP_OPT_REFERRALS, 0);
