612771 - RHDS 8.1/389 v1.2.5 accepts 2 identical entries with
different DN formats
https://bugzilla.redhat.com/show_bug.cgi?id=612771
Fix Description:
This patch fixes the upgradednformat utility to eliminate the
duplicated DNs found in the upgrading period. Assuming DN:
attr0=value0,attr1=value1,...,attrn=valuen exists in the DB
and another identical DN is found, the second DN is renamed to
nsuniqueid=<uuid>+attr0=value0,attr1=value1,...,attrn=valuen
, where the <uuid> is the unique id assigned to the entry when
the entry is added to the server. The modification is logged
in the error log.
In addition, there was a bug to handle multi-valued RDNs in
slapi_dn_normalize_ext. In case multi-valued RDN appears with
DN value (e.g., nsuniqueid=<uuid>+cn=uid\=<uid>\,o\=<org>,dc=<dc>),
it was not normalized properly. Introduced second rdn_av_stack
(subinitial_rdn_av_stack) for the nested DN value.
