What:
Description: Upgrade LDAP master and slaves to OpenLDAP 2.4
Deliverables:
All LDAP servers running OpenLDAP 2.4
See the final report.
Why:
Customer: All
Case statement:
Our SL5 LDAP servers are running OpenLDAP 2.3 (2.3.43 on the slaves,
2.3.38 on the master). This is no longer being actively developed or
supported by the openldap community. 2.4.x has reached 2.4.23 and
appears stable and reliable so we should upgrade our servers
accordingly when we move them to SL6. We are already running 2.4 on SL6 clients.

How:
Proposal:
Resources: 1-2 weeks of CO time.
Plan:
- Test syncrepl replication using 2.4 (for slaves)
- Test slaprepl (standard client) replication against 2.4 server (from
both 2.3 and 2.4 clients) - Test prometheus and any other tools against 2.4.
- Upgrade slaves
- Upgrade master
