Subject: [PATCH 164/225] Ticket #47692 single valued attribute replicated ADD
does not work
https://fedorahosted.org/389/ticket/47692
Reviewed by: nhosoi,lkrispenz (Thanks!)
Branch: 389-ds-base-1.2.11
Fix Description: Add special corner case handling for the case where
- attr is deleted with vdcsn and adcsn CSN1
- attr vucsn is NULL
- incoming mod/add has CSN2 where CSN2 > CSN1
in this case, just keep the new mod/add value as the present value.
Platforms tested: RHEL6 x86_64
Flag Day: no
Doc impact: no
