Security Software

We are using Oracle 8.1.7 and Oracle Internet Directory
products. Our system uses DBMS_LDAP package to update the OID
with the changes to the database through triggers.

I have an object class which a few mandatory attributes and two
optional attributes. Both the optional attributes are single
valued and indexed.
However if I try to add an entry for the object class without
the optional attributes, it comes with the error:
ORA-31202: DBMS_LDAP: LDAP client/server error: Type or value
exists.

I cannot figure out why it is giving me this error as the
attributes I am not sending are optional. Surprisingly, if I
provide one of the values, the operation goes through. Can
someone tell me what is it I am doing wrong? and what can I do
to correct or work around this problem?


Thanks,
