Hello Quanah,

indeed there is no ITS for this issue so far.
I was not sure, if I should make an ITS, because this SYNTAX shouldn't be used any longer (see http://www.openldap.org/lists/openldap-devel/200902/msg00067.html) , but as I stated before for downward campatibility I am also of the opinion that this is a bug.

And if you also think this is a bug (and it will be fixed), every other question is obsolete, since then there is no need for me to migrate the attributes.

Hi Frank,

A couple of things:

a) I don't see any ITS filed for this issue.  Generally that means if this
is a real bug, nothing will/can be fixed, since it hasn't been reported as
a problem.

b) I still see that this syntax is part of inetorgperson.schema and in

static slap_syntax_defs_rec syntax_defs[] = {
       {"( DESC 'Binary' "
               X_NOT_H_R ")",
               SLAP_SYNTAX_BER, NULL, berValidate, NULL},

so it appears to me that it still exists as a valid syntax, using
