I manually tested that to make sure - yes, it's the empty string in the cur=
rent implementation, not null.=0A=
=0A=
    if (zend_parse_parameters(ZEND_NUM_ARGS(), "r|sssssss", &link, &binddn,=
 &dn_len, ...) !=3D SUCCESS) {=0A=
        RETURN_THROWS();=0A=
    }=0A=
    fprintf(stderr, "binddn=3D%llx binddn_len=3D%d\n", (long long)binddn, b=
inddn ? (int) strlen(binddn) : 0);=0A=
=0A=
Outputs `binddn=3D23ddbd8 binddn_len=3D0` when the second argument is null.=
=0A=
So yes, it's currently an empty string, but only if null is passed.=0A=
=0A=
Named parameters cannot be used to skip passing those UNKNOWN parameters ri=
ght now.=0A=
`ArgumentCountError: ldap_sasl_bind(): Argument #2 ($binddn) must be passed=
 explicitly, because the default value is not known`=0A=
is the output for `ldap_sasl_bind($resource, props: $props)`=0A=
