how to search for custom attribute-types

["Nick Laqua" <Nick.Laqua@newtron.net>]

Hi all,

We set up an openldap-server (2.0.23) on solaris using an oracle sql backend. We are using some custom object classes containing custom attribute types.
When issuing search statements like the one below, we are told that we are using a bad filter (logfile):

filter=(&(objectClass=*)(smartiSupplier=10))

output (logfile):

  0000:  30 00                                              0.
    attrs:
conn=0 op=7 SRCH base="dc=webedi,dc=newtron,dc=net" scope=2 filter="(&(objectCla
ss=*)(badfilter))"




As soon as we are using well-known attributes like cn or mail, or  change the original filter like below, everything works fine:

filter=(&(objectclass=*)(smartiSupplier=*))

In the last case, obviously a PRESENT Filter (LDAP_FILTER_PRESENT) is used instead of an EQUALITY Filter (LDAP_FILTER_EQUALITY) and then it works although the same custom attribute is used (smartiSupplier).

any idea ?
