Dear Folks,

1. Can I use the unique overlay with the dynamic cn=config

configuration?

Yes

...

2. If so, what is the LDIF syntax for the configuration?

Use slaptest to convert a slapd.conf to cn=config and see?

Okay, with OpenLDAP 2.4.21, a directory cn=config/olcDatabase={1}bdb was created containing a file olcOverlay={0}unique.ldif

whose contents include: objectClass: olcOverlayConfig objectClass: olcUniqueConfig olcOverlay: {0}unique olcUniqueBase: [suffix DN] olcUniqueAttribute: [attribute to be made unique] structuralObjectClass: olcUniqueConfig

...

3. Would this work with OpenLDAP 2.3.43?

No idea,

Attempts to use slaptest: # slaptest -f slapd.conf-unique-test -F slapd.d-unique-test WARNING: No dynamic config support for overlay unique.

WARNING: The converted cn=config directory is incomplete and may not work.

config file testing succeeded

but 2.3.43 is deprecated. Use a current release.

CentOS 5.5 provides 2.3.43. RHEL 6 will provide OpenLDAP 2.4.x. We want to avoid the overhead of maintaining our own packages of OpenLDAP. I'll only deploy my code on systems that don't use the unique overlay before RHEL 6 is available.

Thank you again for your helpful reply.

Then rely on someone else's (Like the one's Buchan pointed out). But don't rely on RHEL's, and expect to upgrade much more often than RHEL upgrades theirs.
