Diego,

You and I have the same issue. UID and CN are not in the schema they
are compiled into LDAP some how, so there is no way to apply an
ordering rule. I can not find if this is possible, or what is involved
in making it happen.

I'm currently testing a quick and dirty hack that I made to servers/slapd/schema_prep.c:

By making these changes I've been able to get around my current problem, but it might not be as stable as you expect.

You can find these attributes defined in the code in servers/slapd.

However, I will note, the definitions of these attributes are RFC defined. They have no ORDERING rule on purpose.

Thanks for the input Quanah, but the problem is we have some legacy applications that used a really old LDAP server where this was allowed. I'm trying to migrate the server (that's a fedora directory from fedora 6) to a new openldap-based one. I must, however, maintain compatibility with the existing applications.

Is there any problem (despite not being RFC-compliant) on enabling ordering on these attributes?�
