Hi Bryan, Thanks for the quick response. Hopefully we can get this incorporated for OpenLDAP 2.5 series, and I'm interested in playing with it against 2.4 to see how things change when used with Mac.

ITS#5944 configure options --program-prefix and --program-suffix
by hyc＠symas.com 11 Nov '09

11 Nov '09

The OpenLDAP configure script and Makefiles don't do anything with these options. Sounds like you're looking at a RedHat-specific issue.

(ITS#6373) syncrepl subentry support
by hyc＠OpenLDAP.org 11 Nov '09

11 Nov '09

Full_Name: Howard Chu Version: 2.4/HEAD OS: Linux URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (76.91.220.157) Submitted by: hyc As discussed in this email thread http://www.openldap.org/lists/openldap-software/200910/msg00059.html in some situations it's necessary to store the syncrepl contextCSNs in a subentry of the database, instead of the context entry. Syncrepl in 2.2 used to do this but most of that code was removed in 2.3. It needs to be resurrected and usable as an option.
