odd substring search behavior in 2.0.14...

[Iain Moffat <ipm@ufl.edu>]

I am in this process of testing openldap 2.0.14 in preparation for a
migration from 1.2.11.  Environment is AIX 4.3.3 with gdbm 1.8.0 and as
stated above openldap 2.0.14.

When doing a substring search for cn=*ipm* the query takes forever and
causes high cpu load due to the query. 

On openldap 1.2.11 the query reponds with 14 entries in less than a
second.

As per the slapd.conf

index           cn,sn                   pres,eq,sub

the substring index should be present and in fact seems to work for longer
queries (4 characters or greater) such as cn=*ulme*.

Is there a substring index length difference between openldap 2.x and
1.2?  Can this be adjusted? Any help is appreciated!
