>= (greater or equal) and <= (lower or equal) operators in search filter

according to RFC 2254, one can use >= and <= operators in a search filter.
When I try it on an attribute like uid and cn, with openldap ver 2.1.22 it does not return an error but a 0 results and in logs I can see filter="(?=undefined)".
Is that because
- openldap ver 2.1.22 does not implement that part of RFC 2254. In this case, does newer version do this (and which one) ? (although http://www.openldap.org/lists/openldap-software/200208/msg00598.html seems to tell it's already implemented).
- uid and cn have no ordering ? In this case, what shall I add to the schema to make use of these operators on an attribute ?
